Re: My first telly TV22
So got it back on the bench
Looks like the line output stage has died - No line whistle no EY51 heater.
I have checked the voltage at the grid of the PL81 and get -10v wrt chassis - so I take it this means I have line drive - interestingly when I apply my DMM to the grid I seem to get a line whistle coming back (I think) nothing on the screen though - and I can probe and check the EY51 for life at the same time.
I have checked the windings of the LOPT for resistance and they seem somewhere near right though I know this proves nothing much as there coud be a shorted turn.
Any ideas what I can check to prove health of LOPT?
I have a NOS PL81 arrived just this morning.
