If a 2622 type transformer is used:

"Use 1000pf for decoupling before the 2622 primaries.  One on the Hi side and one on the Lo side.

Primaries should be in parallel as previously noted, 1:7 Ratio. Recommended

Zobel is 220pf and 10K R. The load R after the Zobel should be 150K.

This will pretty much get you where you want to be.

Best, Jeff"
