D&R compressor/limiter: question

[The Niz]

Dear,

I've got 2 D&R mono compressor/limiters (see pic) manufactured in 1976 which I wan't to check out (before buying them). One problem: I don't know what power supply to connect them to: I'm pretty sure it is AC, but how much Volts?

I'm waiting for an answer from tech support of D&R, but meanwhile I'd thought I'd try this forum. Does anyone has one of these?
Any thoughts on other old D&R outboard?

All info welcome.

Greetz,
The Niz

Which is either very bad or very good

They are definitly going to use DC. You are missing the main power supply. The main supply converts AC to several DC voltages (like +15,-15 etc.). You must find out from either the manufacturer or look at the PC boards closely. They might be labelled somewhere.
