Both are identical in restoration. I installed some very nice amperex/Japan. All level and 90% plus. Clear top rca 12ua7 tubes. Cords have been replaced with new.Rca were still clean so opted not to replace. You will not be disappointed.
These have very little noise. I ran this with the Conrad premier ten.
I also wanted to point out the gain pots are on the front. The item "Pair of Vintage Ampex Tube Monoblock Amplifiers 30watt Restored! El34 Rare" is in sale since Monday, June 28, 2021.
