How much is my 20/20 worth?

[Steveda]

Hi everyone. I bought a like new Mesa Boogie 20/20 poweramp at a garage sale thinking I was going to use it for my Pod XT live. As it turns out, I think I might have a bad tube or two. One side works great, but the other side I get a ton of feedback when I turn up the presence control. Anyway, I since then have purchased a new Dual Rec and love it, so I need to sell the poweramp. What do you think its worth? I see prices on Ebay, but the one I have seems to have an issue on one side? Let me know your thoughts? Could it be a tube problem?

Thanks for all your help.

Steve.

if its a tube problem you might want to get new tubes and just test it out. but if it isnt i would get it fixed if it is affordable because you can get much more for it obv. if it works totally correctly. its prolly a tube problem.

I think a tube too.
take out all the input cables and leave only the 20/20 loaded with the cabinet, so then increase the volume, could you hear a perfect oscilate tone???? if you could there aren´t the tubes and you have an oscillate that requires tech service
