Replaced the 200R in shunt position to RC55y 604R and now were are cooking. Listening to Santana and the level is about where I would normally listen (casually). That corresponds to between steps 12 & 13 with 10K in series. 200R was between steps 9 and 10. I will try a CD with more level and see if it is too much.

Where is that 6 pole switch you were going wire. It may end up that is all you need.

I am looking at it right now.
Les W gave me it last time I went over.
Working out the lower volume and upper volume resistor values is going to be a doddle with one source but when I get the turntable and phono1 going the upper resistor value may need to be higher.
Suck it and see, I can always change them later when the vinyl source is up and running properly.

Ok will treat it as temporary.
Yes you are probably right, it will never be finished. It would be good to take it home though. But then i would have to build a system to keep at work
I just love building things, learning and discovering stuff.
