I have bought this RM5 mkII preamp which arrived to me DOA.
Apparently the HT secondary winding is interrupted.
As I leave in Italy, sending it to Ramlabs will cost me a fortune so I was thinking to have a new transformer custom made with the advantage of a 230 volts primary. Problem is I don't have any idea of what the voltage out of the ht secondary would be. Could not find any official schematics; the seller willing to make this unfortunate purchase right has written to Ramlabs but got no answer.
I'd really appreciate any useful information on the transformer specs.

I havw seen a diagram with a secondary at 160 vac for Hv and 9 vac for filaments
And it is reasonable for 6922 with regulation
