Hi Gents, in most instance's a valve type with differing prefix letter will always use the same heater power (V*A), so it is quite easy to make a small auto transformer to act as a "voltage shifter".
As the power is low quite small transformers can be fitted under the chassis. They would also have a low turns count as the voltage is low.
