Hi all. My first post on the new forum.
OK, I've just purchased a UA 1108 preamp off eBay from the States. I need a little help deciphering the schematic so I can wire it up.
Does anyone here know anything about this particular model? Any useful wiring diagrams or so on.
The only schematic I have found on the 'net is this one:
http://www.waltzingbear.com/Schematics/Urei/UA_1108.pdf
It doesn't have any clear, idiot proof labels on where I shove my audio signal or where to put my +24 V if this is indeed what it requires.
Thanks in advance. Will :O)

Hi Rob,
Thanks for the response. I've actually had some luck finding some information:

The only trouble is finding the Gain Trim nibnob which appears to be a mystery part noted only in drawing #10733.
Anyone happen to have this one?

just connect pin 6 to pin F and connect to groung as per the notes. This control if installed allows the unit to have a crude limiter. I reckon the Input trim control is just a pot, say 500R would probably do it. Some experimentation required!
