Hi,
I recently bought one interesting WSW preamp(K.Nr.811602).I have pictures of it.It's something like line driver used in radio.The unit works, but when not speaking on the mic the noise raises and then again when making sounds on the microphone the noise disapiers???I'm wondering is there a chance this pre to have build in compressor or something like that?I can't find nothing in the network about this device.It uses 2x 4.5 V batteries(it's some kind of portable device)I have pictures!! Sounds really good next to my GAP 73 MKII. It has more character and interesting mids.It's germanium and has beutiful transformers! Can't find schematic.What can be the reason for this noise?Can I fix it?( I have some skills)

Can you guys tell me where is the gain potentiometer in this schematic( pls see my other posts in this topic!) I suspect this "A, B, C, section next to R10 and Rx(can't see the number of it) Here 's the schematic once again:
