Here is an original, unrestored Harman Kardon HK250 Stereo power amp. Known by some as the poorman's Duece.
This one is ready to be serviced, polished and put into daily use as your main amp. I did notice a small bulge on the end of one of the PS caps. It comes with a quad of Chinese made Golden Dragon KT66's and two HK marked 6CG7's.
The flash makes it look a bit nicer in a few pics than it may be. I did a bit of test polishing on it and it appears as though it will clean up nicely.
Asking $300 plus shipping on the HK250.
Thanks for looking
