Hey-Hey!!!,
I got my old CItation II up and running after completing a PS rebuild. I also replaced all the old carbon comp resistors when I got into it and replaced all the capacitors. The original WW resistors stayed.It sounds good, and is not lacking in power.
The meter is not serviceable, so I am going to put in a jack and keep the switch provided by H-K. The old dual bias pots also left, replaced by sealed individuals of 10k each.
My first impression is that this amp is something special. More time listening will be needed, but that's a job I can do.
cheers,
Douglas
