Thank you so much!

Amazon has the first version of the RP600M on sale right now, they work great with this amp!

Thanks for the update!

Wow, thanks!

Great tips. I hope to put an info page on the website this week.

yeah, 7025 works well too.

I've got all the parts to build one here :)

@@SkunkieDesignsElectronics Hope that this 2A3 amp is your next YT project and comes out right after the new BOM and updates for this amp over the 6SQ7 version.

Yeah, it's a GREAT sounding tube!!

12AT7 maybe? I like vintage Tele, fwiw.

Dave Hartwick take a look at the plate characteristic curves. A 12AT7 is very linear. Try 12AY7 instead. See the 12AT7 tube data sheet.

That's why I went with the Edcor.

Not sure yet. I need to get the chassis work outsourced to be able to do that, too much hand labor to just put that much work into a kit.

Of course!

If you dont mind me asking Steph, u mentioned 600v solid wire, where can we get this? I struggle to find it at normal prices. Also what model edcores are they, assuming 5k or 3.5k.

15W 5K Edcor and yeah I had to buy 100ft spools to get this 600V rated wire.

Sorry, as of right now I don't ship outside the US.

@@SkunkieDesignsElectronics oh no 😢

And honestly, if someone expects a hand made in USA amp, that are individually burned in and tested, both on an analyzer and listened to before they are shipped, using high quality hand picked parts, for the same price as a poorly engineered mass produced China amp off Amazon, they aren't my target market.

Not yet, I have a pair of Chorus II speakers but honestly my room is too small for them to sound good. You'd probably want to do something like triode strap the EL34's and run no feedback with those speakers?

My listening room is only 20' x 25 ' which is probably why the amps driving those Cornwalls is critical. Hard to believe, but I use an old set of ADCOM pre and power amps (250 W per channel) and those sound very good, but they are getting tired and show signs of needing recap (left channel getting weak). I'm an engineer, but not electrical engineer so I only understand the basics of electrical voodoo. A friend (electrical technician) has measured the wattage of normal and MAX LOUD listening levels and those go between 0.5W to 5W max (at 5W I need to straighten all the pictures on the walls afterwards). Experimenting with the location of the Chorus II, you might find them really good, but they are not like the old-school Klipsch stuff. Anyway, shopping for a new power source for those old speakers and it sounds like you care, which is increasingly rare now days.

@@herbieschwartz9246 They might be the last of the old-school Klipsch stuff. I have a pair - always wanted KHorns but see no good reason to buy anything else.

I honestly think this amp wired as triode with zero FB might sound really good with those speakers.

7W, best used under 4W to allow some headroom for transients.

Easy, JJ EL34L. These new Horizon tubes from Psvane are also very good.

US only for now, sorry. And the price for the "basic amp" is $1950 USD

Probably the worst possible match for this amp. "The Quad ESL-57 is no easy task for an amplifier. Firstly, it is woefully inefficient: the speaker has a sensitivity of 83 dB at 2.83 volts"

@@SkunkieDesignsElectronics Thanks. I get the 34 and 84 mixed up. 7 watts, no way of course, but nice work and engineering.

Absolutely. It easily drives a pair of RP600M.

@@SkunkieDesignsElectronics Steve Decart of DECWARE is only a couple of hours from me.

He makes good stuff.

Their signal and their EL34L output tubes are reliable and sound great. If you notice I am using a Sovtek 5AR4, the JJ rectifier tubes are horrible!

Nope, and CE is a joke❗

CE Bages? We don't need no stinking CE Badges! Sorry, I couldn't help myself.

Sorry, no. If you need that I would use a pre-amp that has that function.

More dynamic is how I would describe it. The 300B has a unique sound, maybe more musical? Hard to describe, they both sound very good.

Not right now, a SE 6L6 would be pretty low powered.

Yamaha Kart racing engine from the early 1980's.

@@SkunkieDesignsElectronics COOL! 😎 Shifter Kart? Looks big.

Nah, 100cc open class, ran on methanol power range was between 10,000-15000RPM. Won lots of races with it.

The output transformers limit the use to 60ma current tubes. Any of the 25W 8 pin tubes can be used.

@@SkunkieDesignsElectronicsOh ok, thank you. Can we do a single ended version? 15 to 18 watts? 🤞

Look up my videos on KT120 monoblocks.

@@SkunkieDesignsElectronicsNew to your channel and really enjoy your videos. The TS KT-120 you went through has really surprised me. What junk! My last batch of KT-150, eight of them for my Mike Sanders V4 mono blocks, lasted 6+ yrs till the highs started to become dull. Even though they still held rock steady bias. I never knew tubes were such a crapshoot. Mike was known for his tube testing , guess he certainly proved it to me. Anyway I hope our tube situation finally resolves itself. The Russians I don’t trust either, but the Chinese if paid enough can produce better, only if we will pay?

A push pull amp has MUCH lower bias point, so these issues I ran into don't show up.

Right, I've learned a little bit of second order harmonics is nothing to worry about.

Cathode bias which some folks also call "auto bias"

Patience :) of course I will show all this.

Huh? I'm pretty sure you are the only one laughing at your comment...
