If it's only when you hit a note then I don't think it's tubes or caps.  The issue is probably incorrect (insufficient) voltage to one or more of the tubes. Similar thing happenned to me and my tech also missed it, I don't recall if I made a thread here or not... yeah - see my posts in this thread:,134.msg35654.html#msg35654

Basically it could be a voltage drop resistor in the power section (doubt it; but seen that issue in a lot of fenders, and once in a Solarus 6550) or the screen resistors intermittently opening  like my issue in that linked thread.  A bump could do that; the screen resistors are carbon (vs wirewound like plate etc in these amps) because in a UL amp like this they act as a safety fuse.  Trouble is between the heat and age, they get cooked and brittle, so a drop could crack it luike mine.  The leads are rather thick (they don;t make em like dat no mo) and act like a spring to force the 2 haves together making contact, but hitting a norte creates a momentary open as they vibrate.

Note also that the circuit boards and terminal strips are rivetted to the chasis.  These rivets work themselves loose over time so any ground connection relying on that chassis contact becomes unreliable.  I have found this to create some noise as well (makesw the trem act weird - it starts modulating the background noise not the signal.  The bad grounds are easy to check for and fix;  if you find one, drill out the rivet and replace with a screw lock washer and nut (locktite recomended).

You can check with Conrad Sundholm and see if he still has some. If he doesn't then it is probably gone.

2-3 years ago I bough big piece of Sunn tolex from Fender dealer, but it's no longer produced and stored by them. Angela Instruments doesn't have it too. Do you have any idea where can I get it? I need any piece still exists!  :-D

Only when notes are being played. Ordered all new tubes and caps. Just waiting on them to arrive and when they're installed, go through everything that's been suggested on this site and the gear page.

Is the weird noise all the time (e.g. when you're not playing) or only when you strum a note?

I have a couple of questions for you on this amazing find on Amazon. I know that it's asking a super lot of you, but would you be willing to email me some gut shots of the wiring inside the footswitch enclosure and at the plug, or draw a quick sketch of the wiring and plug pin assignments? I have a friend that has been looking to footswitch for years. I'd love to surprise her on her birthday with a brand new custom (built with love by me of course) footswitch.
