Hi all,
Update; was connecting up to my variac and removed rectifier which is indeed a British 4 pin standard jobby & I got my eye on the output bottle which is shown as a pentode on the drawing I have. However on pulling it out it is a 4 pin British base triode ACO44 The audiphools PX4 .
I have bunged it on the avo valve tester and it shows 95% emission so that valve on its own is worth many times what I paid for the radio. I shall not be splitting it from the set though as I am not a supporter of such vandalism.
Back to the variac. All AC voltages from the transformer check out ok and the unusual dial lamp which also illuminates the tuning meter is still working.
That's me finished for the day. Off for my tea and leave the rest for another day.
Paul.
