Thank you, I know this web but can not see the R-Core or Z11 Laminated wit proper voltage & power required and don't want order a custom made because is very expensive, I search 240 or 260VAC & for filaments 8.5 or 9VAC.

I've used these in the past, mostly for prototyping. Does the job and not too pricey.

Valve Transformer VT342

Why 8.5V heaters? 6922 is a 6.3V heater unless you're planning on DC heater supply.
