Thanks John. I ran the set in darkness and could see a blue discharge from the end of the white disconnected wire to the primary and could hear a faint hight voltage 'tearing' noise from the speaker. The PL81 looks rather impressive with a slight blue glow. I switched off and got a bright but not intensely bright spot from the screen which is encouraging as the tube could be OK
.
I did look for any arcs or sparks from the scan coils which are very loud! What sort of resistances should I get for each?
The disc caps don't test S/C and nor does the .5 cap which I lashed together with 5 0.1 X caps. I shall carry on checks tomorrow.
