Cary SLP-05 Trim Pots

To be honest, I don't really know but I run an SLP-98. Most tube preamps do not need a bias adjustment, unlike a lot of amps with power tubes. Let me look for a manual. Yup, the manual is online at Cary. 

Thanks I looked in the manual too. I didn't see anything. It has two trim pot inside the top or where the 8 6SN7 are located. The 2 pots seem to adjust the 4 in a cluster. The other 2 on the same IC board look like they are for the XLR (balanced) side, but no trim pots.

I'm wondering if anyone knows what they are for? Cary won't give up a schematic on a current production amp. They don't look to complicated.  From what I can see this is stock. There are NO modifications. No fancy caps or added capacitance to the power supply. Stock I think.

I know the pots reduce what ever is going on by turning them CCW with the units OFF and unplugged. They are trim pot according to a DMM.

Without a service manual, you are working blind. You can call Cary and ask but don't expect an answer you can use.

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

Try posting the same question on AudioAsylum in their tube section.

Thanks, someone somewhere is bound to know.
