Hello James,
The boards in my Thaedra are numbered as follows:
Head Amp: 324C
Phono 2 : 523
Line : 522
Mode/Fil: 327D
Tape Sw : 325C
Power : 321C
Since it would appear that the boards have
gone through revisions, are these boards the
latest boards? It it possible to assemble
a "best of" Thaedra from other Thaedras?
Is it possible that boards from Thaedra II have
been mixed with your original Thaedra? Hopefully
mine is not "mixed"!
Best regards,
Paul Bigelow
