Hadley 621 preamp at a bargain

This is one of the great unknown preamps from the 60s and 70s, with RGR and Sumo being a couple more examples. The Hadley is one of the best examples of how to copy a Marantz 7t, and at the same time clean it up and make maintenance as simple as possible. Hadley worked off and on at Marantz, and back in the day made his name for improving the 7t and the 8B with his design efforts. Not mine - I wouldn't be selling it.

hey. I used to own one (same one twice actually)...Its a great unit..ran it with a Hadley 622 amp...cool stuff.
 
1963 seems really late to still have an FM-AM simulcast position on the selector dial.

Seems to be a very impressive early solid-state unit, though.
 
Whatever it was, you may have to add a few $ for current value since it was 8 years ago.
Inflation and all...
