Thanks Shaun! Really appreciate it, have a great day!!

Thanks Franck, you are welcome, all the best!

Thanks Flubutur, really appreciate you tuning back in, I've MIA ha ha.

Thanks so much SK, hope you are having a great new year my friend and thanks for stopping by again. Take care!

Thanks so much, Phillipp. Thank you for stopping by again, have a great day!

Thats great, real good profession to get into, hope to pass on some tips and hopefully some of this info might come in handy. All the best!

Thanks so much KG, really appreciate it!

Thanks Funk!!

@@elams1894 Took the time to read your blog on electricity. @ least someone out there is thinking & working stuff out for themselves. Instead of parroting off whatever BS the web excretes into the vacant lot of peoples "minds" Will @ some point purchase your entire plan suite. Bought an Epiphone valve jr as a tone improvement learning platform. Once that no longer sounds marginal (1/2 way there already & its my first). Your plans are next. Don't stop. Quality work is a rare & precious commodity. Cheers

@@elams1894 Thankyou 😃 !

Thanks FS, massively late reply but much appreciated, beautiful city brother! Take care..

Thanks Shim! I agree about the resistors. Carbon films are fantastic. I'm not a fan of carbon comps myself. metal film, or carbon film preferably when I have a very nice build to look fwd to. All the best with the pedals, cheers!

Thanks Jo Jo! Sorry for late reply, cheers

@@elams1894 Mate, you have to support this channel kzfaq.info/get/bejne/d6-CmbimxJilZps.html please support haha i won the bingo

That's awesome Chris! Well done. Especially regarding you using second hand parts. That's what its all about. It is a challenging layout, especially with the wee switch and sorry about the layout diagram colours, I can imagine that would be difficult. I have since overhauled the layout diagram in which I have replaced the colour terminations with actual leads. I have also made a Series 2 circuit which retains the clean/crunch switch, the channels of which have their corresponding cathode caps with no additional switching. As I like the cathode caps in their designated channels, I have removed the 2P3T switch in the Series 2 circuit. This does a couple of things, makes it a bit simpler and takes away more noise. Although that switch is a cool thing, I believe it may not be entirely necessary. Also, I have designed a GT circuit for this same WISC preamp, which has a very nice tone stack. I have completed the layout diagram for this also. If you would like these reworked circuits please give me a PM or drop me an email and I will be happy to share them with you. Cheers

Matt! Thanks so much for tuning in after iv been MIA all this time. Hope you are doing well and having a great new year. Real nice to hear from you, cheers.

elams1894 that's OK I do that too, sometimes I dissappear from channels or social media for a while so I can understand, thanks 🎸☺

Hi Chris! Super sorry for late reply. Not sure how I missed your comment. So glad to hear of your builds and upgrades. Also wonderful to hear that you got alot our of the amp despite the size. I completely agree about the versatility, one can get generate alot of tones. Thanks for letting me know your feedback, much appreciated!

@@elams1894 Awesome lookign series. Im in Australia, before I buy the plans, what is the rough cost estimate for the build?

@@scottcooper6644 Thanks Scott, I'm not exactly sure what the cost is at present due to covid. It all depends what you can source from Oz. I use transformers from old NZ Bell Colt radios that cost me about 20$ a piece. Decent switches can be obtained from old radiograms and projectors that people throw out, so I grab those too. Those are real cost savers. However if you are buying new, I would estimate that thick end if 500$. If you are resourceful, you can do it a lot cheaper, depending what you have lying around. Hope you guys are doing good over the ditch, crazy times.. Cheers

@@elams1894 thanks elam! I'm finding out pretty quickly that this is an expensive hobby haha.

Thanks! Indeed very good points. I'm not actualy sure why I've not mentioned cap foil orientation. Thanks for highlighting the subject. I'll include it in the next video which is not far away. Have a great day!!

Thanks Kofi, really appreciate the kind words. I don't have any spare amps at the moment as they go quickly, but will be building a few soon. I mainly build my amps with 230V connection so if any need to be built with 120V connections, they will have to be pre ordered. On RCA's... are you planning HiFi outputs? If so, they will need quite a bit of modification as the guitar input is low whereas HiFi is quite a bit more powerful, so input level needs to be factored in to your design. I have designed a HiFi amp circuit, email me on elams1894@gmail.com and I will send you the circuit so you can get ideas on the input. Thanks agin Kofi!

Greg! Thanks so much for checking back in, thought most subscribers would have probably lost the faith by now ha. I got swamped at my previous job and had an addition to the family so spare time did not exist for me. I've since been let go from my employment hence some much needed free time. I am using mostly a Macro Takumar 50mm f4 (1:1 preset version) for this video, in addition to a Takumar 50mm f1.4. I will be also using my SMC Takumar 85mm f1.8. All are M42. They are wonderful lenses, especially the macro. If you ever come across Macro Tak preset, they are wonderful, grab it with both hands. Perhaps my best lens. Skyscraper guitars, cool, I look fwd to following the crimson guitar build, glad to see your still making vids and well done on the products and website, I saw Woodeso had a few, great stuff! Have a great day!

That's the beauty of YT... If you have to set it aside for awhile, it will be here when you come back! I'll check into those lenses. I am a bit of a photo bug!!!

Certainly is possible, that would be a grunty little amp, Fender Champ style. Cheers TG!

Thanks heaps! It is certainly 1$ for the whole plans pack. Don't worry about the other options. The whole plans pack for 1$ includes all the others. I made it one buck as an introductory offer. Thanks again!

thank you.

Hi Thijs, thanks for checking out the vids. Indeed tube amps are a fantastic journey albeit a long and windy road, but there is light at the end of the tunnel. First off, solid core cable is just solid copper, no strands. It is easier to bend, stays in place, however will break if bent too much. Use solid core for areas like filaments, or hook up wire that is intended to stay in one place. Use stranded for shielded cable, or any cable that may need bending often during construction. Use any components and/or materials that meet specification and/or take your fancy. I like using as much vintage, old stock, recycled first and foremost, and then any part or component that is at least partially decent, i.e., anything made in Japan, USA, Europe. I stay clear of cheap stuff and the mega expensive. Buy what you can, when you can, I guess, as long as it is up to correct spec. Hammond transformers are good quality, nothing at all wrong with them. I use second hand, vintage transformers that meet spec, as I can source them here in New Zealand for cheap and they are very high quality, even 50 years old. I deconstruct old tube radios when I can get them cheap, but they are becoming more and more expensive now. As for an understanding of what is going on in tube amps, that is an epic journey, and one that is entirely up to you as nothing is set in stone. You can go down the quantum mechanics path and delve into particle, electron, physics... or, like me, if that makes zero sense to you, you can go down magnetic field theory, which, IMO provides significantly more understanding. However, it is an arduous journey and perhaps be prepared to un-learn everything you think you know about electricity. Drop me aline at elams1894@gmail.com if you have any questions, by all means.

Hi Allen, yeah had a website just to get some amp designs out there. I've got three or four more designs completed but just haven't got the spare time at the moment. Thanks for checking in again, cheers

@@elams1894 Great web site, love the photos. I also followed on Instagram and Flickr, if you care to look at my Instagram,(I have about 30 or 40 photos posted) it is "guitarwoody". Will probably order the amp plans next time I get paid.

@@allenwoody5909 Following! Great shots of the train over the bridge. Some beautiful texture images too. Love the contrasty atmosphere of the imagery. I'm pretty keen on photography myself, just waiting to pull the trigger on a new camera, maybe the Canon R6, if i can somehow find the funds. Message me on instagram and I'll send you the plans. I have overhauled this amp somewhat, simplified the switching, and have upgraded the layout diagram. I'll send the new stuff through to you, its quite wee beast of an amp.

Hi Chris. Thanks for the message, yes the error in layout drawing slipped out, however it's now been corrected, thanks for that. I have had no trouble with the 1/2 watt resistor in the R22 position but certainly to be on the safe side a 2 watt resistor would be a good idea. Cheers

Thanks bart, and cheers for instagram message!

Yes their values can drift which, I guess, can give rise to unique tones over time.

Thank you! This amp costs around $500 USD to build. Cheers

Hi Jol. You can use any transformer you like really, as long as it's around 530V - 550V centre tapped. I use transformers sourced from a vintage tube radio. If the primary transformer from a vintage radio can power at least 4 tubes, and its in the voltage ball park, you should be fine. Which part of the world are you from?

If you want to message me on Instagram, I can give you more info like email address. I have just completed the plans for the Mark 2 version of this amp which I'm about to put on my website. Same circuit, just simplified switching for more stable output. The diagrams are far superior too. Let me know if interested.

Hi Petar. The ideal transformer used for this amp is one that can handle up to five tubes small tubes. For example, the ones that you find in small vintage tube radios. The ideal secondary voltage is around 540 volts under no load, 270v - 0 - 270v centre tapped. Also the transformer should have an additional 6.3v winding, centre tapped is ideal but you can get away with a 6.3v winding that is not tapped (just let me know as there is a separate schematic for that) An ideal transformer is one manufactured by ClassicTone in the USA, model number 40- 18085. This is a great, grunty little power transformer and will work just fine too. Cheers

Yes. Use a TRS jack with a stereo cable to foot pedal with the potentiometer from the amp. I would highly recommend using fully shielded cable.

bassmann446 thanks..I just thought how cool would it be if you could control knobs on your amp with an foot pedal for those moments you want a little more from it; whether your gain or volume.

Cheers David, yes I had a new addition to the family and I was working full time and studying full time so had no spare time at all. Ive since lost my job, which is a good thing TBH, and enjoying some much needed time off and family time. Take care and happy new year!

Not really. They are limited in high end response and tend towards heavy distortion. If you want to get into hi-fi amps I would suggest looking at dcgillespie's threads on the audioasylum board. He has some nice simple designs.

Auckland, kiwi indeed, yourself? Cheers

Nice! New Plymouth for me. Good to see some good home-grown electronics vids!! Rock On, bro!

+Matt Tucker Yes they are PRP resistors, US manufacturer.

I use either Jupiter Vintage Tones or Sozo yellow caps, both are mustard replicas. They sound outstanding to my ears. Thanks

The red 1% resistors ?

They are red Astron replicas.they are pretty pricey and I used them as I was interested in their tone. I would say that they would be great for sparkly clean amps, however, the yellow mustards are perfect for crunch tones as they have fantastic note separation.

Hate to keep bothering you, however at 9:22 into the video you talk about Red colored resistors. You like them because they are red . Am I missing something ? Not caps.

Sorry mate, I was thinking this was a different video for so.e reason. The red things are indeed resistors, PRP brand resistors. They are metal film and look great in red. Not sure they are any better than similar brand metal films however they have long leads which I really like, cheers

Like a buck is going to break the bank.
