Schoeps CMC3u/CMC5 Amplifier Cleaning

This is an upgraded Duran amplifier.

The interior condition of that CMC is pretty crazy.  The XLR leads, RF bypass caps, both electrolytics replaced with japanese units, also probably the FET, and 1 gig resistor have all been replaced. The circular connector has been removed and replaced with nuts and bolts.  The whole amplifier structure seems to have been stripped and replaced, including the transistors, which should be closely matched and have a mininum current gain of 450, typically 500, and they should have an RF bead on the base lead.

That is one scary looking CMC.  Was that a repair job or someone's attempt at a hot-rod?  That thing is so Frankesteined that I don't think you can really call it a Schoeps any more...  Do you know the history of that unit?  Was it water-damaged or?

[tourtelot]

No need to take a peek at the inside of Pete's re-works.  They are spotless. :):)

 

Oh, and Dalton  Great idea for near-field mic testing.  Would have never thought of that.

 

D.

 

PS.  If anyone has any CMC4s for $250 each, I'll buy them all.

So much history. I cannot say for sure this was the exact mic used, I won't speculate.  

 

It is the real deal. No hotrod. 

 

@pverrando I have a 12T Power Schoeps with your name on it as soon as I get some extra cash. I've only heard positive things.
