There will be changes to the circuit as it will not have a very high HT probably be around the 220 Volt range to match the HT rail of the TV I will also be reducing the Ia down from the 36mA spec to about 15 to 20mA. When I had an external amp on the TV it was only about 200mW.
It will be a get the spec sheets and figure a bit out, then stick it in my DC valve tester and confirm any operating points, it my way of learning a bit more.
