I just copied and pasted my post from TGP. Maybe one of you dudes have some suggestions?
I purchased two identical Soldano-designed Yamaha T50C 50 watt combos. The amps are pristine in and out and havent seen any road/heavy use in their life. These amps still had the original tubes in them as well. Basically I started with one of the amps and swapped some of the preamp tubes out until I got it sounding awesome.
I then moved on to the next one. It seemed to be really tired sounding on the clean channel and when you switch to the drive channel you get a slight hum and hardly any volume. I did what seemed logical and swapped all the tubes from the one I had up and running really well, but to my surprise the issue remained even with all known good tubes. One other very interesting thing is that on the clean channel the more you crank the reverb the louder the amp gets and the verb get SUPER wet as well.
I have visually inspected all the caps inside and they all look fine (no bulging or leaking). I also didnt see anything else that looked odd to me.
Check this video I just shot of the issue. The volume I have the amp set at should blow my face off, but as you hear it doesnt. Also notice the verb gain thats added. The other amp doesnt act like this whatsoever as verb is turned up.

Any tips fellas?
