Paragon System-E PS schematic needed

[BigE]

Does anyone have a schematic for this power supply?

Failing that, can someone fill me in on the specs of this capacitor:

Sprague 36DX 540-450 WVDC 7452L

google reveals only that it is discontinued, but no specs ie, I have no clue of it's value.

Similarly, there is a quad cap in the unit that is unmarked.

The general layout of the power supply appears to be a CRCRC filter. (C1, R1, C2, R2, C3), with the two C2 R2 C3 sections attached to the initial CR in parallel.

C1 is the Sprague, the quad cap holds the other 4 caps used in the parallel CRC sections.

Each of the of the C2R2C3 sections powers one channel.

The voltages are approx. V(c1) 420, V(c2) 380, v(c3) 290.

the transformer is a 300V AC, with full wave bridge.

The PS powers a total of 6 12ax7's, 3 per channel. According to the sylvania sheet, the Plate resistance of a 12ax7 at 250V is 62.5K Ohms. If memory serves, R1 looks like 30K, R2 6.8K.

Problem is, I can't model this using the duncan amp simulator due to the parallel CRC section.

Any idea on what the quad is or better yet, SHOULD be?

Thanks for any help...
