Apex 435 mod project

[niva]

Hi there!

Just bought an Ampex 435 microphone with a defective capsule for 25$. Check the pic attached.

So, I want it to be my first mike mod project.

I read a lot fo good things about the JLI Electronics capsules and I was wondering which one you recommend to replace the dead one? TSC-1 or JLI RK-47? Other? I am also tempted by the Aliexpress stuff but I know it is hit or miss...

So here is the schematic of the 435 mike (original) and another version with the components in red upgraded.

What do you think of the mods proposed?







Thanks!

and another version with the components in red upgraded.

"Upgraded", in what sense?

"Upgraded", in what sense?

Values changed according to the original schematics if indicated and replaced with better quality components (Muse caps, polystyrene caps, etc.)
