Harman Kardon FM only receiver ??

I picked up this HK in "non working" condition. Replaced a fuse and both channels work well. It has FM tuning only. The unit sounds great, but not much power. Any one have info on this? It is an Eight Twenty.
The research I did came up with nothing. None of the knobs are original.
Thanks

Rob

The Seven Twenty, 15 wpc and the Eight Twenty, are lesser known and forgotten models in the h/k line. There is virtually nothing on them available on the web. Even the h/k website does not list any info on them. They do not seem to command a high price on resale.

PS, Rob, should you ever consider selling it, pls consider letting me know. I would like to add it to my collection of 60s and 70s h/k receivers.

Thanks for the info Joe. I guessed it to be about 18 WPC. I will be letting this one go, as I just wanted to repair it and see how it sounded. The dial lamps work but thats it. No others work. Some of the lamp leads are broken. The knobs are not original nor are the feet. I will contact you reguarding a sale. I may have the original feet. Unit looks nice for its age.

Thanks again
