1920s RCA UZ-4083-A (4-A-1) Condenser Mic Capsule S/N:3486 - MINT&WORKING!

CVPA is selling its mint 1920s RCA UZ-4083-A (4-A-1) Condenser Mic Capsule S/N:3486 - in perfect working condition!

Note: This is the capsule only and will need a mic head amp for operation.

Check out the YouTube demo (scroll to the end of the pics) of this actual capsule in use!

This capsule would be great for a vintage mic collector or DIY vintage audio enthusiast: you can use this capsule with virtually ANY single-diaphragm condenser mic circuit (the audio test was using a simple AKG P170 mic body wired with a shielded cable to the capsule - took about 5 minutes to setup!). The common/original RCA amp for this was the AA-4088 - a 3-stage mic head amp utilizing UX-864 tubes (NOT INCLUDED). There are schematics available online for this amp.

Capsule mounts with standard 4-40 screws around the perimeter.

Note: This sale is for the mic capsule only, NOT for free comprehensive tech support for your personal DIY project - though I'm known to give a few helpful DIY hints to paying customers who are friendly and patient (in my spare time on weekends).

Condition:
Outer capsule surface has small scratches and/or tiny dents throughout - still mint condition for a near 100 year old capsule.

Diaphragm has small dust particles and felt fibers from the packaging felt - no dents or scratches that I can see - for its age I'd say its mint condition and it sounds amazing!

Vintage tin capsule container may or may not be original to the unit; appears to have "RCA UZ-4083-" with the "B" scratched out. Could have been a capsule installed into a 4-A-1 mic from the factory and then placed in a newer RCA UZ-4083-B container when they removed it later.
