RE: Marantz 8B with Bob Hovland Mods?

Posted by jonsan on June 12, 2020 at 09:15:11:
Many years ago I had a pair of 8Bs modified by Bob. They were wired for mono and triode operation. The input tubes were 6HK5 and had 5687 for the phase splitter. I'm sure he replaced the selenium rectifier but as far as I know the power supply was otherwise stock. Of course the coupling caps were Hovlands. So basically his circuit using the 8B chassis and transformers.They sounded great.

In a fit of temporary insanity I sold them but no doubt most of us have similar stories. I have no definitive information on resale value but as in most things stock generally brings more $$.

In person Bob is the most gracious, unassuming, down to earth person you will ever meet.
