Krell KRS-2 with KRSP-2 power supply. External transformer needed..

[gebi]

Just got from an auction this beautiful Krell KRS-2 with KRSP-2 power supply. BUT the external box with the transformer is missing.
From what I see in the first pic: 4 transformers for 2 voltages and 2 channels.
Should be not difficult to build a box with these.

Question: Does somebody know about the needed transform secondary voltages / ratings?

PS: The cable from the KRSP-2 to the KRS-2 with the Lemo connector I do have.

Thanks
