Need help with broken amp!!!!!

I got an old fender bassman amp from a buddy yesterday. It sat in a basement for a good number of years, and i have no clue how to even approach fixing it.
I can turn it on and get power and i hear a slight hum from the speaker but thats about it

The first thing you always check on a tube amp is the tubes. Make sure they're all lighting up first.

Re: Need help with broken amp!!!!!

well if it was stored in damp environment there could be corrosion on the internal parts which could short or give cold solder joints. Also capacitors do have a self life and are sort of like batteries in that they need to be used and can go bad after setting inactive for so long.

crack open the amp and look for obvious issues like burn marks from damaged parts, or rust/build up, look for loose connections and anything out of the ordinary.


be extremely careful some capacitors can and do store large amounts of electricity at more than enough amperage to kill/seriously injure you. As long as your just looking and not poking around you will be fine.

if you dont see anything wrong you'll have to find and invest in a good amp tech. Then just go from there.

Re: Need help with broken amp!!!!!

Why someone who stated he doesn't have a clue how to fix an amp will open an amp and look at its parts?
And even if he saw something he thinks is wrong still he doesn't know how to fix it.
What a waste of time and sometimes money having to pay for medical treatment after touched something he shouldn't.
Take it to a tech, don't open, don't touch it

A SS Bassman is not even worth taking to the tech. They are worth maybe $200 o a good day, you'll spend more than that on bench fees, junk it and be done with it. I would however salvage knobs and the like off of it first.
