CCS is your friend!

[Gordy]

I know that this thread is quite old, but the following caught my eye...

The full quote from rdf:

Would it be possible to combine a balance pot with a CCS? Something along the lines perhaps of a small value pot, wiper to the top of the CCS and cathodes on either end with safety resistors to cover failure? The potential is appealing because I've regularly seen 3rd and higher go 100 dB+ down (<0.001%) in SE with CCS plate loading and current trimming into reasonable loads, leaving only second. A means of nulling that in PP mode holds the promise of crazy performance.

The part of interest:

The potential is appealing because I've regularly seen 3rd and higher go 100 dB+ down (<0.001%) in SE with CCS plate loading and current trimming into reasonable loads, leaving only second.

Can you please post an example schematic showing this type of 'SE with CCS plate loading and current trimming' stage, so that I can learn?

Thank you.
