I own a ’60 Harvard in museum quality (1 owner very rarely played and stored away for 47 years). It runs perfect. Great recording amp or even for small club venues. Puts out 14.2 Watts (measured with NOS tubes). Absolutely loving it!
would love to see pics:)
I have a 59 in pretty great shape …
The tweed and brown Harvards were very different amps. The 5F10 with its three inputs feeding a 6AT6 was an oddball circuit, shared IIRC only with the tweed Vibrolux. The 6G10 was essentially the tweed-Princeton 5F2-A with hotter transformers and somewhat higher voltages.
Great info. I’ve got a rebuilt Harvard,,, no cabinet. I can find vintage 10″ jensen thought about rebuilding cabinet,,,???
