Hey Folks,
Some of you might already seen the topic of toroidal transformers for ribbon microphones in the 'White Market' section. Finally, I found a nice toroidal core for the condenser microphones. It is annealed 80% Ni tape wound core, with the size small enough to fit in MOST of the microphone bodies and could be used even as a direct drop-in in the MXL2001/67G mics. I have already worked out 6.5:1 (ratio of BV8, good for EF86, 6AK5, 5840 and many other tubes), 8:1, 10:1, and 12:1 ratios, but can make any ratio. The pri DCR is well under 100 Ohm (while most of the EI or DU cores are in kOhm range), the transformers are very low loss, distortions, and phase shift.
The main problem is the cores are outrageously expensive in small quantities, so I will need to order at least 50 pieces to make it worth. So the main questions are
1) if people interested in those transformers at all, and
2) how many people would buy them?
Best, M
P.S. Not sure if it belongs to "Brewery", so moderators feel free to move it there.
