Default Re: Can somebody please repair My TV22

Hmm, I wouldnt use this for TV servicing.

How about using a crystal earpiece - stick a 1000v cap on the centre pin of the earphone plug, and probe the oscillator grid to listen for a buzz.... - you will not need it in your ear, as it will be quite loud.....

Time to get a cheap valved scope me thinks

Cheers
Sean
