These actually sound very nice. The tone vontrol box was not tested though. I don't have the other plug needed for parallel power.
The amplifiers both work well. No overheating or funny noises. The amplifiers are slightly different in model, and cosmetically.
I believe one is an earlier model. The face panels are the same, the only difference I noticed on the front panel was the L. The rear panel also look very similar. The main cosmetic difference is the top/side cover.The specs should be the same, but I'm 100% sure. I WILL SEPARATE THEM FOR THE RIGHT PRICE IF NO ONE TAKES IT AS A WHOLE.
