Audio Research or Luxman?

That was a nice suggestion, rwwear2. Unfortunately, the issues with the   volume/balance pots on the Luxman continued to present themselves through the Chase. Balance drift and volume on/off issues persisted. I have boxed the Chase and will be sending it back to the seller.

The Chase volume does start LOW, 2 red lights out of 5 lit. It's volume change is very many small steps, click click click ..., 3rd light, click, click  click ... 4th light  up to 5 lights then a few more clicks.. It ought to get pretty loud when 4 lights are lit.

Try it on a different amp. If volume (all features) does not work, then the Chase is defective, you should return it. You bought on eBay, so even if seller does not take returns, IF it is not what the seller said (working), PayPal will refund the money to you, then they go for a refund from the seller themselves.

Long Shot: One option is to try both outputs, try the rear, perhaps rear is working but the front outputs are dead. They are identical signal, early quad era, not a different rear.

There is nothing inside except a few printed circuit boards and a small transformer, no moving parts, so I don't know how some functions work and not others. 

I had one arrive dead. Transformer Connection broken, evidently UPS played football with it. Seller gave me a refund. Never had any issue with 3 of mine.

do the red lights change when you try up or down?

where do you live? I’m in Plainfield, Central NJ. If close enough, you can borrow one of my working units, I have a spare, and we can definitively prove yours does or does not work.

IOW, perhaps that Luxman has other problems, perhaps erratic.

Elliot,

Yes, the red lights change when I press volume up/down, and I kept the volume button pressed for a long time. When the lights changed it had no effect on the volume level.

I live in Wisconsin, leaving soon for Arizona.

I appreciate all your help, but I'm afraid my Luxman is simply not cooperating with the Chase.  

Jerry.

You will probably need to remove the Luxman volume control from the circuit to get the Chase or any other VC to work.
