Rich,
Thanks for the response. What are you doing to "sweeten" it up? Are you doing anything that would liven up the bass? I need to replace the lamps on mine as one is white and the other has a yellow tint. Any suggestions on adjusting the volume increments? Seems to me they are spread too far apart. I'll try Rick for a manual.

Sweetening Process:
1. Repair any functional issues (general repair, if needed).
2. DeOxit all controls
3. Make any adjustments, specified in the service manual.
3. Correct any cosmetic issues (if correctable).
If resulting condition and value warrants the extra expense/effort, I may do 1 or more of the following:
4. Replace all electrolytic caps, except large power supply caps (unless required by measured value deviation, leakage, swelling, etc.). In this case I use low ESR, low tan-theta, higher temp and longevity parts, if possible/available.
5. Incandescent lamps replaced by LEDs
6. Replace fake veneer with real walnut veneer (receivers could get something more exotic than walnut).
7. If any parts are replaced that would have an effect on the adjustments specified in the manual, I re-perform those adjustments.
That's it in a nutshell. As for the volume increments, those are physical detents in the controls. The model we are talking about uses a detented volume pot. Volume control via rotary switches, switching discrete components, is not implemented till you get to significantly more expensive models. I try not to second-think the designers in this area.
I hope I answered at least a couple of your questions...
