I haven't taken on many projects lately. I was pretty depressed after my storage unit was burglarized a little over a year ago. I lost all of my vintage amps, conversions, and kits. It was hard to work on anything without dwelling upon my treasured equipment that was gone forever. It's difficult to type this 15 months later, but I'm getting tired of my Vibro Champ SX that was the only working amplifier that I had left. Maybe that was the inspiration I needed.
At the time I was robbed, I had on my bench a Silvertone 1482 that I was in the process of rebuilding, and in queue a Bogen CHB10A PA amp that I planned to convert. I've knocked the year plus layer of dust from them, and dug back in.
I've got the 1482 running after replacing the filter capacitors in the power supply, and changing out cathode capacitors. It was kind of a mess. At some time someone had moved the inputs to the front of the amp. I guess they didn't like plugging into the back. I didn't like the look of it, so I moved everything back to the original locations. It's as quiet as a church mouse, and sounds pretty good, but I'll wait to do any other modifications until I get the speaker cabinet completed. I've got a vintage P12R that I plan to use, and want to optimize for it.
I've just started on the Bogen, and haven't done much yet besides gutting the things that won't be needed. I tested the amp initially. It was working, but noisy, and after a few minutes it burned out R14 in the power supply. Today I plan to replace the filter caps, the bad resistor and change the input to something like a champ amp. It's cold here today, and the propane heater has been warming up the shop for the last hour. I'm going in...
I'm not over it, but it's fun to get back into the amps.
