Default Re: Can somebody please repair My TV22

Hi Andi,

The diode trick is a quick and dirty way of getting an A1 supply, but may well be loading the circuit too hard - if the metrosil is producing a voltage then it is probably working.

My first order of business on the sets I have done (5 now) is to get a line whistle - even if it is croaky and weak it does prove that volts are where they should be.

I really do not subscribe to the wholesale replacement of caps untill I have seen the item showing signs of life - HV caps are expensive to throw away on a set until you are sure that you are replacing the right parts.

As others have said, if the EY51 heater is glowing then the lopti is doing something.

Cheers
Sean
