I have no idea what I am talking about,
but what the hell.

could it be either the output or pick up transducer jobers that send the signal thru the spring?

Just replace the "thing-a-ma-jig" on the "osfrigalator" and you'll be fine...........
If that doesn't do it. Grab the biggest hammer you can find and beat the sh#t out of it.
Reverb tanks used to be kind of special to have, but now there like cell phones. Everybody's got one.

That's the key question. If it's an old one and you've eliminated just about everyother possibility (in particular the tubes and the pan), a cap job may be in order. If it's a new one (or the old one too for that matter), try hooking up a pan from another amp. You don't even have to remove either of the pans. Just connect the cables from the combo over to the reverb unit. See if that helps isolate the problem.

Hi Danny,

Sorry to hear about your tank troubles. This is not likely to help any but I’ll throw it out on the off chance that it does… I bought a new reissue tank. And it only worked intermittently. Sometimes it would put sound through to the amp and sometimes not. I checked the cables and such but they were fine. When sound did come out, it was sometimes pretty well distorted. Like using an overdrive or distortion pedal. The distortion was most pronounced when I would hit the strings pretty heavily. Really grind into the strings and it would distort.

My guess was a bad solder joint. Or perhaps even a bad tube. But it was new and I wasn’t about to start taking it apart and resoldering things. In the end, I sent it back and got a replacement tank. Best of luck with yours.

Eh, who cares what everyone else is doing? Tanks sound great and people know when you’ve got a good sound going. My gal doesn’t know much about my tank- she just refers to it as “the box.” And whenever she hears me playing without the tank, unplugged or straight into the amp, I hear her say “Hey, why aren’t you using the box?”

it's been at the tech's about 9 months ago and supposedly all the caps and resisters were checked

Checked or replaced? It might be worth double checking the work that was done. From what I can tell, you gig a lot and probably use that tank quite a bit. If the filter caps (or other electrolytics) are still original and "checked out okay" when your tech looked at it last, they might be getting tired...even in just 9 months. At any rate, I'm sure it's something simple.

Easily 90% of the repair work I see are for vintage amps which still have their original electrolytics or original tubes or both. "It was playing great and then I got this weird sound...or...the amp just sounds weak to me...or...I get these funny "accidental overtones"...or...there's this really bad smell...or...the fuse just blew." Any of those issues could be due to caps and tubes.

Thanks for your help PhatTele, he replaced a few caps and resisters. All the major electrolytics were replaced a 3 or 4 years back. He's very thorough, but you are correct that I gig a lot and things just go wrong on vintage gear. I'll be giving it the wooden dowel test for bad connections and double check the cables, and if I don't find any back it goes.

OK mystery solved (sort of). Both the pans I was using were distorting. When I plugged in a third pan it worked fine. It's definitely some kind of electro-mechanical problem as it seemed to occur in the springs, when I shook the pans they got worse. Perhaps I should try switching out springs? In the meanwhile I have a good pan and I'm happy. Thanks again for all your help people!

Yep, I learned a lesson. I was so focused on drip I didn't listen for purity of tone. It's a subtle distortion and I didn't notice them at first. I'm still not giving up on these, there must be a reason they're buzzing like that.

thanks DP,
I remember people talking about those going out back on cowabunga.
and it seemed to be a possible culprit.

not that I know anything about how a tank works.
but just ringing a bell in my head.

Jeff(bigtikidude)

could it be pan orientation? in other words, is the pan intended for vertical mount in the Reverb box...or is it a horizontal pan?
