6922 Loading Question

dtm1962 · 14th November 2010, 01:15 AM

I have a heavily modified Lite 60 (Monarchy NM22 without the preamp) and I was wondering what is an acceptable load (Preamp) to allow the 6922 output tubes not to be overloaded.

I have a NAD S-300 (built by Gryphon in Denmark) that has a passive preamp (no active components prior to the potentiometer) and a 10K potentiometer. I believe this load is too much for the Lite 60 6922 tube based output.

I sense a little distortion in regards to overload....

I wanted to replace the 10K Blue Velvet Alps with a 50-100K potentiometer to lighten the load for the 6922's.

What are the consequences in regards to changing the pot from 10K to 100K?

Any help would be appreciated.

Thanks,

Less distortion, more noise. How noticeable this would be depends on signal levels.
