Bose 901 Series I Active Equalizer #41550 Repair
This Bose 901 Series I Active Equalizer, serial #41550, came into my shop in need of an overhaul after being stored somewhere sticky for many years. After a rebuild and thorough control cleaning with high powered solvents, this equalizer performs good as new! All new capacitors, resistors, transistors and neon bulb will last for a long time to come.

Bose 901 Series II Equalizer #58189 Repair
This Bose 901 Series II equalizer came into my shop recently. It had one good channel, but the second channel was experiencing a large amount of distortion. No wonder why, the unit was mostly original, although it had some evidence of being serviced before.
Inside, about half the capacitors…

1937 Detrola 139E Vintage Radio Repair
I just finished a new project over at Rain City Audio – 1937 Detrola 139E Vintage Radio Repair
This Detrola 139E chassis was on my bench recently while the cabinet was being refinished. It’s a striking 1937 radio with an art deco stationized dial with a very large tuning area, and even though it only has 5 radio tubes, it’s a great performer. I replaced the rectifier tube and rebuilt the electronics of the radio followed by testing and an alignment; now it’s very selective and will be a safe and reliable appliance for someone’s home.

1958 Sony TR-610 Transistor Radio Repair
I just finished a new project over at Rain City Audio – 1958 Sony TR-610 Transistor Radio Repair
This Sony TR-610 came through the shop to have its electrolytic capacitors replaced. It was a quick service and this iconic 1958 transistor radio came back to life just in time, only having missed a few Mariners games! With up-rated replacement capacitors and a new battery, it will last for a very long time.

1934 RCA Victor 119 Antique Radio Repair
I just finished a new project over at Rain City Audio – 1934 RCA Victor 119 Antique Radio Repair
An example of the 1939 RCA Model 119 radio made its way through my shop recently. I like RCA’s engineering – they were pioneers of radio and even their entry level models like this set had great performance. The styling is classic mid ’30s, too – great in almost any home….

Oregon Electronic Model A3 Variable Voltage Regulated Power Supply
Here’s another project I just finished at Rain City Audio:
This vacuum tube power supply from an engineer’s test bench can replace a radio or test circuit’s power supply to help with troubleshooting or experiments, with up to 400V for B+ and 6.3V 5A for the heaters. It needed some new capacitors, then fired right up and works perfectly! Continue reading

1940 Philco 40-185XF Antique Radio Restoration
I had the privilege of working on a very well preserved Philco 40-185XF recently. These are top performing pre-war sets featuring 8 tubes, an RF amplifier front-end and push-pull audio output into a 12″ speaker. Definitely worth fixing up! This … Continue reading
