Harmon-Kardon radio??

[mhardy6647]

Just an old hk tuner. Nothin' special; probably sounds decent when/if it's in good working order. Probably needs some attention at this late date "for best results".

You can probably find the manual at:
www.harmankardon.com

EDIT: yeppers, here it is: http://manuals.harman.com/HK/Owner%2...ual/A200om.pdf


EDIT^2: looks like this tuner uses a half-wave selenium rectifier. That should really be replaced with a modern silicon diode (assuming it hasn't been already). This will require a little power-supply modification (extra dropping resistor) to allow for the more-efficient silicon rectifier.

Thanks for the info!
I don't have any real expectations given the item description but I thought it might be interesting.
