Hi I founded the Vrat community in 2011, since then it has grown into so much more. We have a Facebook Group and YouTube channel. I hope you enjoy your time with us and check out our other social media presence. Personally I collect and repair early colour television mainly between 1967 - 1977. My other interests include early VCR repair and obsolete media formats such as VCR, VHS,Betamax, V2000, CED and laserDisc. I also collect 1970's audio.

RE: 1974 20" Ferguson 3C03; Thorn 4000 ; Super Rare

Posted by: @irob2345 I think the one you have chosen should do the job. Hi Ian, Phew, that's a relief, I'd bought ten of them for stock, not that I guess I will need them all.

RE: 3D Printing Service

Jamie, that is superb 👍 Even more so when, as you rightly point out, you had to build all that in CAD first, not a quick or simple task. I know I've had a play, just doing a cog, relatively si...

RE: 1974 20" Ferguson 3C03; Thorn 4000 ; Super Rare

Looking at the thick film it looks just like a fancy pot, the wiper is free flowing, meaning no click positions. How important is the Make-before-break in its operation? The reason I ask is, I had a m...

RE: 1974 20" Ferguson 3C03; Thorn 4000 ; Super Rare

My next problem is TF403, this is another thick-film unit used for vertical shift. This unit consists of high-wattage resistor elements that are selected by a make-before-break switch. They have to be...

Did a dry fit on my Matrix board, mainly to find out if I had all in stock that is required, for the main Vertical Def PCB. I've everything, bar three components, C417 75pF @ 500V 5%. All I've got is ...

RE: 1974 20" Ferguson 3C03; Thorn 4000 ; Super Rare

The Vertical Deflection PCB mount/heat-sink, coil and 2-pin plug have finally turned up Jim, many thanks, I reckon RM don't like snow and wind. 👍 So here we have it, I've all the rare bits nee...

Need to use UPS Jim, I'm happy to pay whatever they charge. RM are not fit for purpose and have not been for quite some time. If they've lost the vertical deflection cradle, coil and plug and it's not...

Hi Lloyd, yes it's TF303, I've been trying to fathom what components are in it and its function. I can see TF303 on the cct, however, unlike the vertical deflection TF's which are detailed, there does...

RE: 1974 HMV 2726 Coloumaster; Thorn 4000

Think the HMV might date to 9th September 1975. There is a date stamp on the inside, also Vic Hallam. After a bit of research it would appear this would be the cabinetmaker, they did all sorts of word...
