stepped attenuator

Hi Bob:
I'm wondering where the installation info you originally posted for the stepped attenuator went to? I saw the 2 pages briefly on the this site then you said it was moved but I can't find it again. Was it removed or am I looking in the wrong place. I have a 100K 40 step attenuator I got for another amp that may work in there but I want to look at how it is done on the board to make sure I get it right. I tried it for size and it will fit into my base externally mounted so it doesn't have to go inside the chassis.

Hi Baddog,

The stepped attenuator instructions to install the attenuator into a stock ST-70 are below ..

Thanks Bob looks like a piece of cake.

hi Bob:
I forgot to mention that I have an ST-120 with the VTA board and need to know how the ground wire connects.
The diagram for the stock board doesn't explain the following: Does the ground wire from the attenuator go to the lug on the RCA jack or the board? and how does the ground return to the board if it does? Are there two wires on the lug?

Thanks Bob:
I'm clear on the connections appreciate the help.
How is the KT-120 project coming? Are you still playing around with that project?
I bought a set of them and tried them for a while but will keep them for a spare quad in case I need them. They sound the same as the KT-88's to me.
