"For sale: Fisher model 50A (Z) monoblock tube power amplifier. Made in 1954. Output is rated at 50 watts RMS/continuous. Includes original Z-matic control. It sounds good and works great! You won't find many of these Fisher amps in such good condition.Note that the nameplate says 50A, but it's actually a 50AZ. The tube complement is (2) 5U4, (2) 6L6, (2) 6CL6, and (3) 12AU7. The pictures show bottle-style tubes, but I can substitute those for more modern GT-style tubes.
The transformers have been re-painted, and it's been serviced and thoroughly tested. Some off-value resistors were replaced, the input pot was cleaned, and the tube sockets were reconditioned. Two minor issues: The Z-matic pot/switch should be replaced or bypassed; and a couple of tube sockets are chipped, but they don't affect performance. Shipping weight is approximately 60 pounds (U.S.). Price: $750.00 includes an extra set of 6CL6 tubes."
