Nady TCM 1050 output transformer in the power supply.

Добро пожаловать.
Конденсатор ц8 и выходной трансформатор хочу перевести на питание микрофона. Может ли это как-то ухудшить звук?
Возможно, резистор р8 тоже надо перенести на блок питания?

Because....?

Because....?

I didn't quite understand..

Just curious why you would want to do that.

It's been done:
https://www.filmsoundsweden.se/backspegel/sela2.htmlAt least it could enable building smaller tube mics for TV studios, doesn't help with TCM1050 though.

Plate resistor used with the 6AK5 (EF95/5654/6096) is only 15k, cathode biased via 200 ohms resistor.

First, I changed the capsule to the 47th type.
Removed capacitors C6, C9, C10.
The sound changed, but I didn't really like it.

I tried plate load circuit with native transformer, the sound is very bad.

Then I returned to the original circuit, but with an E88CC tube.
I liked the sound more than with 12AT7 ..
It was already much better.

Next, I brought the wire out from the C8 capacitor and used an external transformer from the tube preamplifier (large size with an iron core).
I connected it on weight, next to the microphone.
The result is a powerful bass, but there is a lack of high frequencies, moreover, this is a dim 47-type capsule..
I tried other transformers, the sound changes significantly.

For this reason, I decided to move the output transformer to the power supply. It will be much more difficult to place it inside the case.

Perhaps there is a limitation on the length of the cable, interference from the power transformer in the power supply. which will affect the sound or noise, background ?
