Re: The very much non-definitive EAR 834P Modification Guide

Posted by PeterK on February 14, 2002 at 10:01:07:

Copyright issues?! After Tim's ripped the circuit off the old Marantz 7c? Lets give credit where credit is due. Other than that it's a really great design and my own spinoffs (of the 7C naturally) were not far off Thorsten's. Two chasis, 4psu, valve rectified of course and a battery at the second valve grid for bias. Why it plays music the way it does, taking into account cathode followers, NFB etc will be a great mystery for me.
Oh, and being slightly allergic to ecc83 i also made one with 6SL7/6SN7 but of course gain needed to be lowered.

best regards
