Title: Sony C37A
Post by: argibbo on June 29, 2011, 05:30:06 AM

Hello

Can anyone help me with the correct HT voltage for the Sony C37A microphone please. I am in the process of constructing a power supply for it and the HT (B+) voltage is not given. I'm going to build the original thermionic rectifier version (which will sound better) if that's any help.

Many thanks in advance

Andy Gibbons
