Awesome looking DC power supply.
I'm guessing it was manufactured somewhere between 1930 and 1950?
oldest tube(s) in your system
Please let us know what they are running in too. Thank you for your attention to this matter...ha!

The system keeps getting older! Replaced the 1958 Western Electric D-getter JW 2C51 with 1957 NOS+ testing General Electric 5-Star (white) 3-mica 5670...but then replaced those with 1951 NOS/NIB Heintz and Kaufman labeled General Electric 3-mica 5670. These, and their factory mates, will be the last and only tubes run in our modified Dodd Battery Powered Preamp (by me anyway) as they've been the most positively transformative tubes I've ever heard. Just Wow! |
@electricboyo Regulated Power Supply 25 by Lambda Electronics Corp. Circa 1955 according to Radio Museum. Smells like a battleship. If you know, you know! |
