Tube Amp Archive

Thanks for the help!! I am probably just going to find a nice clean silverface AB165 locally that I know exactly what has been done to it and go from there.

Peace

This amp will be a potential purchase and i dont have access to it so i am trying to gather as much info to make an educated decision on whether to buy it or not. The seller had modded it to aa864 specs on the normal channel and replaced any faulty components in the process. He rattled off that he p...

In the my previous post the owner described it as hissing and popping noises, if the board is the culprit, would isolating the circuit board from the mounting bolts (standoffs maybe??) be a possible solution?

*If so how common is this

Has anyone ever actually seen a fender circuit board collect moisture and become conductive be the problem of hissing and popping noises, or is it "almost" always a different problem. Has anyone not solved a background noise problem by doing everything imaginable, then changed the board out and it w...

Thats really what i was trying to get a feel for, if someone just told the seller that this was the problem, because i had never heard of it (which isnt saying much) and he went along with it, or if it was more likely a component issue. The amp was gone through when the mod was done, but who knows i...

assuming all components test good.

Ive been watching craigslist and ebay and unfortunately the prices on these are rising. $450 wouldnt be a steal but probably just a fair price, considering my original plan was to get an AB165 and do a similar mod. I dont have a lot of experience working on tube amps, but have decent soldering skill...

I could probably get this one for $450, and would like to put as little work into it as possible.

So I would need a new board and all new components to eliminate this?

I am thinking of buying a silverface Bassman AB165 that has been modded to AA864 specs on the normal channel and a JTM style circuit on the bass channel. Unfortunately I am not able to play this thing before I purchase it. The seller says it has some popping and hissing noises due to moisture absorp...

I guess I wasnt very clear. I am really looking for a description of how the amp sounds if you dial the internal gain trim pot up a little, give it substaintial overdrive and engage the boost. I am just curious as to how this sounds. It is not something I intend to use the amp for on a regular basis...

New to the forum, cant say enough about how great of a resource it is. Thanks for all the information. I am considering building a Ceriatone OTS or OTS HRM (among many others) and am wondering if anyone has really pushed this amp. Almost all of the sound clips and descriptions are displaying how swe...
