Hi, I'm in the way of building a Tubelab SE, my first problem is with the power supply.
Probably I as wrong ordering a Hammond 373HX who put out 350-0-350 , it is 700V ct

This would give me far more than the 400V I was intented to drive the 300b

Now what can I do before buying another transformer?

I have a choke to substitute R4, it is a 7H 200mA that may help, but I think is not enough.

Any suggestion of how to drop out the excess of voltage?
The bad choice was the -bigger is better idea.

Another thing, I cannot find the parts list page for the SE, anyone has it?


Thanks for your help
