You guys probably noticed I'm messing with VariMu variations a lot lately. I am really in love with these tube comps for years, and I just got back to DIY, so I am excited and starting lots of new experiments on breadboard... I mean, breadpoint...
So, is there a reason why I've never see a common cathode resistor for both plus and minus sides in a balanced varimu compressor circuit like this?
This is an example circuit. one could use small trimmers on the plates for balancing operantion.
cathodes tied together would easy CMRR of thumps and noise, and save on a big capacitor for AC coupling the cathodes like Ive seen on some compressors.
Also, not sure, but impedance would be lower on plates, wouldn't it?
So, is there anything wrong or bad about getting the cathodes on a compression stage tied together like this?
Thanks for any inputs!
