If you've been looking at used gear and might be concerned about servicing or repairing it, you might be interested in this person I discovered.
As a Xmas gift to my son, he asked me to find a place that would re-build his vintage Model 173 receiver. It's a very nice sounding 1970's model that was beginning to act up. It took me over a year to find someone willing to do it at a reasonable price. I did a nation wide search and came up empty-handed most of the time. A place in Washington reluctantly quoted a price of $1500 minimum - ridiculous! I originally bought this unit for myself about 8 years ago for $15 on ebay and eventually gave it to my son.
I finally found a guy who agreed to do a total restoraton for $285 and my son is very pleased with the result. His name is Todd Loenhorst, and he has a website called timerider.net. He's in California.
His email is [email protected]
This is the work he performed for $285.
• Fully disassembled and clean. Inputs/outputs cleaned.
• All switches cleaned (pulled, if possible) and lubricated internally.
• All capacitors on all boards replaced, including main filter capacitors
(Audio-quality and/or stacked film capacitors in tuner, pre-amp,
amplifier, protection, power and tone stages (WIMA, Kemet, Nichicon
and/or Panasonic capacitors).
• All Zener and Schottky diodes replaced.
• All trouble-prone or hot-running transistors replaced with modern, low noise units.
• Output transistors pulled, cleaned and re-set with new thermal pads
and thermal grease.
• Heavy-duty regulator transistors on power supply board.
• New power regulator resistors on power supply board.
• New rectifier diodes x4 on power supply board.
• Adjust amp circuit with new Bourns trim-pots.
• Adjusted Bias to factory spec.
• New lamps.
• New snubber circuit on power switch.
• Circuit boards inspected for any cracking, burning, etc. Any cracked
solder joints re-flowed, especially in high-heat areas.
• Bench tested for 12 hours under an 8 ohm load.
