Re: Harman-Kardon F500 FM Tuner Restoration

tune in

Dave, that tuner appears to be manufactured for the Japanese market and  most likely runs on 100 volts AC.  Check the information on the back of the tuner.  You will need a step up or down transformer for most countries outside of Japan and will only be able to access the lower end of the FM band (to 91mhz).

Do we know if more of the boards for the LM4500 will become available?

I'll let you know, I may try a new supplier, should be a month or two most. The one I used was closed until things got better.
