Need 10 amps variable to 6 volts? Here is the equipment for you. A fine bit of vintage test equipment.
This power supply provides DC power high enough for vintage car radios which use vacuum tubes. The power supply is variable, but not regulated.
This piece of equipment was needed to complete some of the projects I am working on, and I stopped working on Part 1 of the 1953 Chevrolet vacuum tube radio
At the end of the Chevy Part 1, we reach the end of the capabilities of my bench power supply in terms of power output. That radio requires 6VDC at 5.5 amps and my current supply tops out at 3 amps. I would rather use a variable supply rather than a battery so that I can have better voltage and current control. I will need to get this piece of bench equipment to continue.
When this piece of equipment is ready, this series of videos on the Chevy vacuum tube radio will continue. Please check out the Playlist for that radio for those videos after they are published.
See the checklist which appears when status changes, for tracking what is discovered that needs addressing in Red, followed by Green when resolved.
NOTE: This is not instruction, it is for entertainment for people like me who enjoy watching projects and the experiences gained. If you attempt to do any of the things in this video you are at your own risk. I am using special tech-bench safety equipment not detailed here so don't take for granted you can just plug these old items in safely without them being checked and repaired correctly. Check out the link below to Mr Carlson's Lab video below.

Thanks to shango066 for championing the approach of "fix it first", before mass re-capping. See shango066 for many examples of that approach.
