multiple Reverberocket 2s picking up radio noise!!!

[doctorock78]

Hi all!
This is my first post here and I am stoked to have joined. My bandmate has an amazing GS12R from 1965 that picks up radio stations. I bought the same model (1967 version) and it does the same thing!! I was wondering if this is common to these and whether there is a known fix. My Fender amps are dead quiet in the same situations (we did compare). If they are quiet there HAS to be a way to get these Ampegs to behave similarly (the GS12R, I dare say, sound better to me for recording than my Fender amps..). Thanks in advance for any insight !!

I'm actually working the same problem with a first generation Reverbrocket. I'll let you know what I find, but I have a business trip next week so you might not have a solution from me very soon. Maybe someone else here already has a fix.

It would help if you would give a few more details, though. Does it happen with a guitar plugged in? Without a guitar plugged in? Do any of the knobs affect the radio volume? Do the amps have 3-prong power cords? Typically these things are related to shielding...

OK. I had some free time this evening and decided to look into this further. As I mentioned above: shielding. What I found when I took the back panel off can be seen in the attached image. in particular, the shielding on the back panel extended to cover only about two thirds of the actual chassis.

I added aluminum tape to cover the entire area covering the chassis. When done, the radio signal coming out of the speaker was *almost* gone. I actually thought it was gone entirely, but with a little straining, I could still hear it. But anyway, pretty good.

Take a look at your amps and report back?

Great info, will check soon. Amps are currently at the techs for tune-up. I do know that alot of the Reverberocket 2s have a full enclosure chassis, so not sure the aluminum tape would add benefit. Worth a look though! Our tech says he thinks he has a trick that may work. Will report back
