Re: A Cogging Pye V110
Oh dear. Just about to box the set up and I heard a horrible sizzling noise with bad line-tearing. Now no picture and no EHT. Plenty HT, good -ve pulses to the g1 and plenty screen grid voltage to the PL81. No other obvious faults measured so far. I'm pussy-footing round the lopty and I still have a few things to check but I fear the worst might have happened.
If the overwind has died then perhaps an overwind-ectomy combined with a doubler / tripler circuit may be required.

Re: A Cogging Pye V110
What a and it was such a good picture. Hope the sizzling is something that can be fixed such as EHT wire breaking down and not the LOPTX.

Re: A Cogging Pye V110
Looks like an exact repeat of what happened to mine. Mike rewound it, very good job and it has worked well since over a long period. Very frustrating when you have spent so long on the chassis. J.

Re: A Cogging Pye V110
I had this happen my v510. Used a thorn 1400 trippler in place of the over wind, only for the primary to fail 6 weeks later. Best of luck with it.

Re: A Cogging Pye V110
Thanks for the replies Frank, John and John.
I think I may well get the trannie sent down to Mike. I think it's probably worth getting going again after all the hassle with that cogging issue. Thanks all. Kind regards. From Mike.
