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….

Overloaded 1931 Transformer [Fried Electronics]
I’m working on a 1930/31 Westinghouse WR-8 Columnaire clock-radio which had a bad transformer. The filter capacitors failed and shorted the high-voltage secondary, burning it open and causing a lot of heat and melting. The replacement is a General … Continue reading

Bad Capacitors Strike Again
I’m working on another Bose 901 Series 1 equalizer. It looks to be the same manufacturing run as the first one I wrote up last July, uses the same components, and those components look like they’ve had the same failure … Continue reading

Westinghouse LCD Repair
After seeing the repair I made on the Samsung LCD monitor, a friend gave me a few-years-old Westinghouse LCD/TV that had quit working – it wouldn’t power on anymore. It’s a Westinghouse SK-19H210S, 19″ LCD accepting VGA or HDMI up … Continue reading

Adventures in Dumpster Diving: Samsung 225BW LCD Repair
I found a Samsung 225BW LCD sitting on top of my apartment’s dumpster, and figured I’d drag it upstairs. It’s a few year old model but it’s better than the current older Dell LCD that I’ve been using (1680×1050 versus 1440×900). … Continue reading

Cost Engineering in 2011

Cost Engineering in the 1930s
It looks like cost engineering was already happening back in the 1930s: In the foreground, the destroyed original power transformer from the 1939 Zenith 7-S-363 radio; the rear, an equivalently rated replacement built in October 2010 by Edcor Transformer. In order … Continue reading
