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.

Engineers make things work and have spare bits when finished
