Pilot SM-254A recapped w/spare NOS output tubes

Pilot SM-245A Integrated amplifier.  Its been professionally rebuilt and all tubes are strong...ALL inputs work, all functions work quietly with no scratchiness or pops.
The only negative is a bit of imbalance at lower volumes...Left is a tad lower, which I fix by using the balance knob.  
The unit sounds tremendous and is extremely quiet with no music playing.  ALL tubes are old stock including Mullard EL84’s.
The cabinet was made by the previous owner and its the strongest cab I ever had...The faceplate is attached to it (It was a console pull originally). 
Tube complement: It has Mullard EL84s and 12AX7s in the amp stage, GE 12AX7s in the preamp, and Sylvania 12AX7s in the phono stage. 
I will also include a quad of Edicron NOS output tubes...8 volt filament tubes that should last forever.

Important:
Regarding the balance, itsusually age of the volume pot. In vintage gear you usually live with the issue with an original part until it gets out of hand. In my Fisher 500-C I have an ALPS pot once the volume knob was beyond help. I am listening to the Pilot now, and it sounds great as is.
