Plug for Hi-Tech Audio Carver Repair

[thsmith]

I bought a TFM-55X on ebay a couple of monthes ago. Was in rough shape and was sold as non-working or for repair.

The seller was right, the cabinet was rough, lettering worn off, lamps not working and the right channel had a distorted sound and output was weak. Left channel was fine and sounded good running my center channel.

I figured I would take a chance at $150. I sent it to Rolland at Hi-Tech and had a fast turnaround. I have had it back for 4 days running my mains where the TFM-45 normally lives.

Rolland replaced/repaired the following at $299 (minus shipping):
Replaced driver stages, pre-driver stages, protect stages and updated 20-volt display regulation circuit.

Replaced power supply capacitors in all stages including 15 volt supply for front-end regulation.

Touched up paint on chassis.

Set bias to factory specifications checked supply rail voltages.

Touched up poor solder on the input card.

Replaced the following parts:
(4) 2SC3467 (2) 1N4745
(4) 2SA1370 (2) 12V 90MA Lamp
(2) 6K8UF 35V (4) 47UF 50V
(2) 3K9UF 63V (2) 10KUF100V


I am very please with the outcome. IF you don't count shipping which I never do right or wrong. I have $450 in this AMP that should last for a while.

MY TFM-45 was serviced in 2005 but I am thinking of sending it to Rolland and have him give a once over and install an IEC power plug so I can upgrade the power cable as the 45 is my main amp. The 55X will be center channel AMP and back up.
