API schematic

[Studio Mollan]

Hi,
I'm looking for a schematic of the VU wiring on an API 2488. Probably the same in the 16 and 32 channel versions.
I'm missing this page in my manual...
Probably a long shot but will be very happy to find one.

It's a distant and foggy memory but weren't the VUs on those boards wired from a spare secondary on the transformer?

Hi! Thanks for your reply,
I don't think so though it's worth looking into. The tape monitor section is not fitted in my desk, the owner before me installed pulled them out and installed a rack shelf............ , and according to the schematics I have the VU-amp is located on those cards. I bought new VU-drivers to hook up to the channel out from the input channels. When i was to install the new drivers i saw that there actually is a stock VU driver circuit inside the VU bay, and they do work. My concern is that they might load the source, channel out, if they in fact have been used together with another VU driver.
The driver in the VU-bay is only one transistor and a trimmer.
