PYE LV 30 RF section
Hi all I have just started work on a Pye LV 30 and the first thing I have noticed apart from a naff Brimistor and a o/c dropper, is quite a few split caps and a couple of burnt ones on the R/F section, they are those awfull Hunts miniture mould things there are 29 of them !!!! 0.001 uf 350 v there is so little room,I think I can remove the whole section from the chassis which should help a bit, can anyone suggest what I replace them with this is going to be a nasty fiddly job

Re: PYE LV 30 RF section
Hi Danny many thanks for that idea I had not thought of using disks, I will order some tomorrow from RS, I have got the r/f pannel out now so I will have a bit more room to play with, there does not seem very much in this little set but its fiddly, I had hoped with a few choice waxys replaced and a temp dropper assy to fire it up and see if I had any life but all these Hunts have put paid to that now , this is the console set, when I come to do the table model I will have a bit more experience but still loads of problems

Re: PYE LV 30 RF section
I have both the console and tabletop versions of this set. When I got mine I was rather horrified with these little Hunts horrors. I ordered a supply of 1000pf @ 450V from Maplins and then got down to each set. I found a number of these in very awkward places and very well hidden, it's very easy to miss one, I also believe there were one or two outside of the RF assembly if memory serves me correctly.
I noticed that most of them went to chassis on one side (you need to verify this with each one), so I carefully went through and replaced every one, but I didn't do the chassis connections until I had got every replacement condenser in place. Once I had done this I then carefully connected them to chassis, sometimes sharing a common connection with a number of the condensers. This did make it much easier. When completed both sets worked well and are still giving a good reliable service. I hope this may be of a little help. Peter. |

Re: PYE LV 30 RF section
Good morning,
are you talking about these? I think the RF strip is the same in the FV1. Kind regards Darius |

Re: PYE LV 30 RF section
Hello Darius,
Very similar to the FV1 but the LV30 is TRF. The FV1 was PYE's first five channel superhet [FIVE VISION ONE] and continued with the FV2 and FV4 series. Great sets that give superb pictures. Alas all HUNTS horrors! Regards.JOHN. |

Re: PYE LV 30 RF section
When restoring my LV30, I , like Den, removed the RF chassis to give better access. After changing the caps etc. I powered the chassis using a variac for the heaters and a bench HT supply. This meant that I could prove my work before re-installing it in the main chassis and made alignment very easy. This also worked very well with a Pye B16T (My bench is fitted with an isolating transformer so there was no risk using the variac)!
Cheers Brian |

Re: PYE LV 30 RF section
Hi all thanks for your input on this, I have been held up on this set waiting for some more caps to arrive, I now have them, there was also nasty 600v ac wax cap on the main tagboard, I finished the r/f chassis ok it was a bit tight in places !!! but not as bad as I had thought it would be, in the end I managed to get some 100pf 650v Vishay miniture caps !!! the same size as the ones I was replacing,I have made a temp mains dropper up and I am now replacing caps in the frame timebase ect, enough to try and fire the set up without causing damage.
