ARC SP9 Preamp voltages

[topfee]

Dear mates
I got a SP9 preamp from the old days that has a power supply transformer gone.I sent a fax to ARC asking the transformers secontary AC output voltages (it has 3 output voltages) and I got the anser that they can't give me this information (it is a 15 years old unit).
Please anybody has a preamp like this and can help me??

Best regards
Kyriakos

from my schematic the transformer has two primaries
ans two sencondary.

The HV must be 280 Volt, 395 after rectification and the LV must be near 15 Volt, 22,7 after rectification.

Schematic for ARC SP9

Did you get a schematic for the Audio Research SP9? Now I'm in the same situation that I would like to find a schematic also 😀 Because I recently bought a SP9 and I found out that it is slightly modified with two EC92 in each phono stage. The seller said it is for the supply but I'm not convinced.

So does anybod have a schematic so it can be emailed to me?
