Title: Reverb tank on Solarus
Post by: Joe Schorn on May 30, 2001, 12:06:00 pm

The reverb on my solarus head constantly rumbles and crackles. I'm guessing that the tank is just shot.  

Anyone know where I can get a suitable replacement tank? Are these pretty easy to replace? Is it simply a matter of installing the tank and plugging the rca cables back in? Or is this a job for an amp tech?

Thanks. Any help would be much appreciated.

Hi Joe:
Have you tried replacing the cables to the reverb unit. The reverb on my Sceptre became very distorted with boosted high end. Since the connections are RCA at both ends I used a stereo cable to bypass the original cable and the problem went away.

I hope this helps
George

Make sure the 12au7 reverb driver tube is in good shape; if you're in doubt it won't cost too much to replace it...AND...check to see if it is an actual 12au7...sometimes a 12ax7 has been mistakenly used as a replacement, and that tube of course has a higher gain that will overdrive the reverb tank. Take the tank out to check if anything is touching the reverb springs, and if the send/receive cables are OK, use a contact cleaner spray like Deoxit D4 to clean the RCA jacks.

Hello,
I would suggest following the suggestions of the two replies above and try gently blowing out any dust in your reverb tank.
