I really like the sound of this most recent suggestion i.e. just the valve base open with the two diodes and the 4 ohm 10 watt load resistor open to view, especially if that will emulate the conditions for the U10. This was after all one of the two primary objectives;
a) Demonstrate the Mullard HT Unit is working.
b) Make sure I don't blow the U10 if and when I pop it in.
If we can therefore agree that this proposal at post #21 achieves this then that's what I'll do first. If there is then a better solution having re-attached the glass balloon to the valve base so the adapted 1821 can be used on an ongoing basis we can agree that too.
Can I please just check that the diodes as shown in the pic at post #13 are now the right way around too?
Thanks
