Just noticed you said there are 3 12ax7 tubes, I would say this has IC reverb driver, this is a whole different layer of troubleshooting that will need to go to an experienced tech.

Gary

For some reason my Hot Rod Deluxe schematic PDF is unavailable so I pulled up a Blues Deville schematic and noticed the drive is an IC so if the hot rod is the same you’re out of luck on the troubleshooting.

best thing to do is pull your preamp tube covers and make sure they’re all lit. small glow at the base of the tube is the heater.
You could switch tubes BUT some may be 12ax7 and a couple 12at7, you do not want to get these mixed up, the amp will still work but the quality of the sound will suffer greatly.

SO until I can find a schematic I would just make sure of the things I told you so far, make sure it’s not the pan.

And if you’re unsure about anything I’ve said just don’t do anything to your amp till you get with someone that knows a thing or two or it can cost you more money when you get it fixed.

I assume you checked the reverb driver tube? Also the pan transducers inside. Are the wires still connected, sometimes they break, (the part that attaches to the springs)

If you have done all this, do you hear the pan “crash” if you shake it, while it’s hooked up? That will tell you the problem is before the pan, if you don’t hear anything suspect the pan or what’s after it.

Thank you for the taking the time to reply to my question, it’s greatly appreciated.

All the best,

Thanks for the comments. I’m just shaking the can to build up pressure inside the can. I’m spraying inside the pots, in most pots in amps there is a little indention (hole) or an opening near the lugs (points where the circuit is connected).

I usually spray the guitar jack (end of the audio cord) with cleaner and work that inside the jack, or you can spray inside the amp input jack and work the guitar plug in and out to clean.

With Funk Out you only need a little squirt. I try to keep it off the circuit board.
It won’t hurt anything, it’s not conductive but sometimes cleaners will leave a filmy residue on the board. I usually turn the amp off while cleaning anyway.

First of all, thank you for posting such great and informative videos, they’ve been extremely helpful! However, I have a question in regards to the Peavey Funk Out you’re using. I was just curious as it’s difficult to notice in the video if you’re shaking the can or spraying it, but are you solely using the spray to clean the pots / inputs, or are spraying the product directly onto the circuit board?

Thanks in advance for any help and thank you again for your useful videos!

All the best,
Michael

Thanks for the kind words. If anyone is interested here is a link to the book, a guy at Groove Tubes turned me on to it:
