Rare Vintage D&R Compressor/Limiter

Jitter · Mar 6, 2018

Hi guys.
I'm a owner of a pair of rare vintage D&R Compressor/Limiter.
I wanna know what is the tipology of this compressor.
I think that it can be a fet compressor, but the bridge diode in the circuit confused me.
Here the manual:

Hello

Fet compressor, T1 and T2 !
Diodes in the SC section of the circuit, wave rectifier.

Ok, thanks for help!

Yes, this is a FET compressor. T1 and T2 are the gain reduction JFETs, and the diodes are part of the level detector that drives the JFET gates to perform gain reduction.
