Cary SLP-05 Trim Pots

I’m new I need help. I have a (new to me) 10 year old Cary SLP-05. There are two (2) trim pot inside the chassis that has the tubes (not the rectifier tube). Are they to BIAS the tubes? It came with tubes but they are not labeled where they go. They are all Sylvania 6SN7-GTB.

I can match the tubes that’s not the issue. I just want to make sure they are BIASed correctly, matched and place to optimize their performance.

I’m new to Cary.

I sure could use some help.

Thanks

Thanks russ69, I called Cary. They told me NO MAP on current production equipment.  I know without a map it's pretty hard to get there from here. Hopefully someone knows something. I guess I could draw a schematic, and look at the way the older preamps are set up and get and idea. It's not rocket science. I guess it would help if I was a rocket scientist. I use to be a pretty good plumber, does that count?

My guess is for adjusting the balance phase when using the xlr's.

Similar in SF line preamps.

petg60 you got me. I'm a handyman at best. It sounds like I need a scope and someone that knows how to use it. :-) I haven't moved anything but I did index the pots just in case they get moved.

Thanks
