Everything you need for a tube amp bench supply:
My reconditioning process:
Specifics about this unit:
$200 plus shipping, or trade for a working high quality bench multimeter or VTVM (+/- cash if necessary)
- 0 to 400 VDC B+ supply, up to 125mA
- 0 to -125V C- (bias) supply
- 6.3 VAC heater supply at 4A
- 12.6VAC heater supply at 2A
- Voltage and current metering on front panel
My reconditioning process:
- Replace all electrolytic capacitors
- Test all other capacitors and replace if necessary
- Test all tubes for shorts, leakage, and emission, and replace if necessary
- Clean all tube sockets, pins, and potentiometers
- Repair or replace any nonfunctional components
- Blow out dust
- Clean exterior
- Replace damaged fasteners
- Test under load
- Calibrate and test output
- Calibrate meters and test for accuracy
- Remove and pack tubes for shipping
Specifics about this unit:
- Used cosmetic condition, stickers and scratches.
- Bias supply adjustment pot is a little "twitchy" in the -16 to -30 volt range. It's steady once it's dialed in. If you want to, it's a simple 50K pot replacement.
- The film capacitors were barely in tolerance, so I replaced all of them as well. There are only 3, if I recall correctly.
- I originally wasn't going to sell this, so I used whatever electrolytics I had on hand. All in spec, of course, just not fancy ones.
- It came to me with 6P3S pass tubes instead of 6L6GC. These run within spec for Vak at any useful B+ voltage, and within dissipation spec unless you're pulling lots of current at very low voltages. I run these in an identical unit without issue.
