Hi again chaps.
I've been building a large capsule condenser mic over the last 4 years. I'm still stuck for the gold sputtered mylar. Any ideas? So far I have the body, valve electronics and the capsule built. I've skinned it with 20 micron aluminium film and have actually had sound from it, though it does sound a bit 'telephonic'.
Hopefully, as part of my university course, they will let me build the power supply as a project. (Going for the Sony C37 PSU, early type, because it has valve rectification) Does anyone know the HT voltage output from that PSU?
Best regards
Andy
