McIntosh MC75 (Pair)

The listing is for a pair (2) of vintage McIntosh MC75 power amplifiers.  
They were originally used in an industrial or lab application.  The volume control had not been wired for consumer audio, and there were some extra "holes" drilled for various wires.  I installed a chrome plated cover cap on the deck of each amp to cover a 1/4" opening.  
Each lacked a volume control knob, so I added one that clearly shows the level (vs. the homely stock knob), and rewired the inputs to standard MC75 factory specs.   I also replaced four resistors on the OPT (to match the original schematic) and added 
Illuminated AC power switches substitute for the power receptacles in the front, which are really convenient.  I checked the caps, resistors, tubes & etc. and replaced electrolytics as needed.   
My intent was to bring the amps to essentially "stock" condition (with slight increases in the values of some of the electrolytic capacitors).    
Each has pairs of tested vintage GE-6550s.  All of the small signal tubes are of US, British, or German manufacture.   
The workmanship is careful and neat, and they sound glorious.
I will package the amps and the tubes separately (3 boxes) for shipment within the CONUS only.  Freight charges will be at actual cost + PayPal fees (I,.e. "out of pocket" reimbursement).  I will ship from my office (either UPS or FedEx) where we have preferential rates.   
Please note my long-term feedback and purchase with confidence.   Thank you!
