You definitely deserve more subscribers. Everything clear and concise. Good job 👍

Damon you always provide great information on old school RF amps

Love watching the Vintage Rockford Fosgate get repaired! :-)

Awesome video. Very helpful, please do more. You explained everything in full detail without rambling on.

Man I love the old school content nobody's doing repair videos of old school repairs like you do looking forward to the PPI,soundstream,kicker etc 👌

Nice video, you are definitely right about "Heat Sink Compound", I think every time I open an amp I .wipe off the current compound and put down new. I also replace the thermal pads with Kapton tape. Ready for the next one.

Here I am using more than one word when only one is needed....Nice! Thanks for the vid. I am starting to repair car amps and from what I see, your videos are going to be very informative and top notch. I think I have found a guru who is on par with they guy who taught me how to refurbish tube audio equipment. I am looking forward to seeing some more of your videos, keep up the good work.

You are an electronic ninja! Thankyou

I have what i thought was a RF Power 301s since 2004, barely today as i was cleaning it realized it is actually a 551s; after 16 years this thing still works and is about to power its 4th set of subs

More old school rockfords pls. And more detail on the output drive circuits and setting bias also 👍🏻

You are the man, thanks for the great video and detailed instructions.

Love your explanation of this ,what a wealth of knowledge

Wow! I have a Punch 360a II! I love old punch amps!!

One thing I’ve noticed is that many of the old DSM/IX/x2 series of amps don’t use thermal compound. They use some sort of material between the transistors and heatsink that looks somewhat like cardboard. And these are amps with intact warranty seals, so it’s DEFINITELY from the factory. Not sure if this is something that deteriorates with time.

i have this amp in my truck right now, its fully working, a friend gave this - after looking for one- I'm younger (I'm 33) and never had an A-class amp, and the stories from the old guys are true, its better sounding than the new ones = and they don't make one that compares to these old ones anymore - sound quality is equal to a PSaudio amp... if you could buy one (good luck) pick it up .. audio-files buyers

ill try to act surprised... hahaha love it. great videos keep them coming. personally I like how you shoot the videos..

I have an old rockford power 500.1bd that has a problem so looking forward to seeing if I find the fix on your vids. It would power up for just a couple seconds then the power light would go off, it did that a couple times then the power led quit coming on all together.

Nice vid. Great info and straight to the point...thanks for the shared Knowledge...it would help a Lil if u said if it applies to most amps in general or the one u working on specifically

Great stuff, I learned something! I didn't know Hickok45 was into diy car audio repair.. 😆

Hi sir I have one like that when I put it on the mosfet started to heat up when I take off the remote wire and put it back on several times then it came on good and working I change the driver ic 494 but same thing

I bought a 301m and the guy had it in his truck and took it out and sold it to me. He didn't have the car running or anything he did it properly, but I've never gotten it to work since.

very helpful, thank you!

You are my new hero! I’m hoarding up some of these and you are doing the exact one I own in this video and just picked up a 500.2 that is untested. Great info thrown here and love that you explained so that a beginner/novice can understand or learn from. I took electronics but was so long ago my Dean was Benjamin Franklin Moving on your next vid before popping the covers on the newest acquired. Do you have the specs for the potentiometer for the punch control by chance? I have one I can take apart if not. Thanks again

You are very knowledgeable and do a great job where you located and do you work on other people's amps

Got a p1000×2 turns on wont play! Was my buddy's don't know what he did but what can I look for?

Would be awesome to see you repair a Rockford 450s. I have one that is blown, mosfet issue. Can't find anything on it. Seems like a rare amp.

I have a few amps I bought that didnt work. I've been wanting to fix them. Thank you for your videos. But if anything how much do you charge to fix one

Thanks for doing this, would be nice to see some old kicker ZR/ZX amps as they have their fair share of problems and are quite common.

“Awesome” !!! I am subscribed and will be viewing everything! Very detailed and informative content! I’ve been a huge car Audio enthusiast for a long time! I’ve recently started looking into rebuilding subwoofers and had a few blown amps laying around. I’ve opened up a punch 500x and found burnt spot on the board! Would appreciate any help with this greatly!

Do you fix these for people punch 45 w/tm on sticker no output but powers on

I have a 401s amp and has the remote broken I was able too open it and stick it back in , i powered it up and the sound it put out sound like cracking and popping

I got 2 bd1500, 1 power 800, 1 power 1000@2 , and a power 601.2 if you can fix 1 or even both bd1500's you can have the rest!!!!

Can you repair my Rockford fostgate bd1001 3000 watt it makes a buzzing noise when powering on and when you turn up the gain it gets distorted

i was wondering if you would possibly consider repairing my old punch 800a2 if so let me know a price and and an address

I love this! Your videos are extremely informative! Can you do a video explaining how does one go about determining where the PNP and NPN fets go without the help of a datasheet and also how to set the bias. I'd really appreciate that bro! Keep em coming!!👍👌

Hi what size resistor did you use to drain the filter caps ??

Good repair documentary I need help trouble shooting my Rockford Punch 800a2 when I connected the rca’s before I hooked up the ground wire and it sparked now I have no audio from channels power light comes on do you think the opamps fried don’t know please and thanks.

I just bought a punch 360.2, 120a2 and a 250a2 that still had end caps, I was going to disassemble them and give the boards a alcohol bath and throw the heat sinks in a parts washer maybe some new paint and reassemble with new compound. Whats the common failure of these late 90's rockford amps?

Thanks for the cool video. What kind of old school Soundstream amps do you have to repair? I have 3 myself that I want to refresh.

Early 2000's power bd1500.1

So if we have something like a US Amps that the fets are along the sides vertically and the thermal paste is easily accessed and is still wet and gets everywhere after you touch it would it be ok to run as is?

hello i have some amps that need repair do you do repairs as a service?

There's cheap scopes out there these days (yes limited options but good enough for this type of work). Go ahead and use one to show the output.

I have a older power 400.4 and when I it plays the sound will go all to the rear right speaker and when I kove the gain knob it will go back to all 4 speakers. Sometimes at least. It has blown a couple of my 6x9's cause of this problem. How do I fix this problem. I love this amp but can't run it now due to its problem. Please help me

On old ppi amps what's your thoughts on replacing the caps?.they have been sitting in original boxes for over 20 years now .

Good day I purchased one of this old amplifier . Work fine but a have a pulse sound coming of the speakers event went the r/c off. Any idea what wrong with the amp? Thanks

I just replaced the thermal paste on my old db 1800,s

Hellow Mr. Shiny Head, (also known as Mr. No Bs./Honest Man) hope you are doing good.. Hey my Old School Mono Amp (A JL/1000.1) produces a like a "Pulsing bass note" at the subs, i can see them cones moving in and out non stop when idling, even if my stereo is all the way down. or Rcas disconnected. what could be causing it? any tips a noviest can do to cure the problem?. thanks

the only thing I hate Rockford Fosgate that they overheat JLAudio is much better instead of shutting off its it goes to lower frequency instead off shutting off .

Do you repair amps as a paid service? I have a couple old Fosgates I'd like serviced & inspected

I have a wierd issue with a rockford fosgate punch 120A2 I was working on, took it apart to clean up noticed it was repaired before anyway I did a quick test with just the board and my desktop power supply seemed fine until I put the board back in the case. Seems that the power supply is shorting out through the heatsink, I can make it work by insulating the heatsink on the power supply side from the case. Can you point me in the right direction to see what might be causing this? I did replace all the mosfets on the power supply side cuz it looked like a crappy repair maybe I have a bad one I dont know.

I have a Rockford Fosgate Punch X250.2 that powers up but no sound. I tested the amp and found a channel that had blown mosfets. I replaced them but still no sound...any ideas why?

What is the link on those remote turn on switches or how can I purchase one ? Mine broke off 😢

Do you do repair amp from out of town repair??

😮

It looks like this amp

How much you charge to repair an amplifier

I'm sorry. I didn't get the volt part. Can you repeat the entire video again?

Could you repair or replace the caps on these old girls ? If so please send me your information and we can get together soon and send them to ya

I need a badge for this amp
