Hi Rob, having been truly inspired by watching your work on Retro Electro Workshop I am pleased to now be subscribed to your channel. I find your work absolutely fascinating, it is great to see the expertise of yesteryear still going strong. I'm an electrician by trade, but would love to learn more about tv and radio repairs. Keep up the great work, I shall look forward to watching more of it.
So glad I have just found your channel. I have watched everything on the US TV repair channels. As a teenager I spent many hours messing around with these old TVs and I recognise so much of what I see in the bush and Murphy sets. I hope there is a lot more content here, and please keep creating. I like your presentation style.
Thanks Eric. I'm glad you like the content. I'll try to post some more videos soon, but I'm so busy with customers repairs that I struggle with time. I love doing the videos, so keep watching.....and I'll keep making them, eventually. 🙂👍
Fascinating video, many thanks for posting it. I'm just really surprised more people haven't found your excellent channel. It just underlines my thoughts that you have to build up a following by posting many videos on a regular basis. Not always possible for busy working people as you clearly are. Keep up the good work.
Yes wrong oil it will get to hot an cook the transformer or at least the plastic around the wires and will go off as mentioned below ..you need a oil that works at high temperatures so will not get to hot motor oil ....These old tvs were never designed well i had one set that the EHT case looked like a black oven in side a wonder it didn't set the thing on fire they didn't test well in the old days ! But every thing said you got it going !
Thank you so much for your hard work. You and all who carry out these restorations are keeping history alive for future generations to come. Well done!
great video...hope there will be more......... veg oil dries out , gets goopy and smells horrible after some time....mineral oil should be the way to go...also for sealing and glueing on High voltage you can and should use non acidic rtv silicone...withstands massive amounts of temperature and is the best insulator for high voltage. just go to a car parts store and buy some sort of "sensor safe" rtv silicone...or any rtv silicone that doesnt smell acidic....most modern ones are not acidic...
Good work, apart from one major error! Should never ever use veggy oil for a transformer of any kind. Reason is, it does contain moisture but more deadly to thin overwind coils is the fact its acidic. As it gets older, it gets more acidic to copper. They use copper in the copper strip corrosion test for veg (and other) oil acidity. Use ask any biodieseler about FFA, free fatty acid. Let's hope the original oil is still soaked into the windings..... Surprised you didn't use a light mineral hydraulic oil, or even proper transformer oil, it ain't expensive!
Great video just wondering why you used vegetable oil, instead of Transformer oil or mineral oil? I think you'll find out the vegetable oil will go Rancid and your telly May smell like an old Fish and Chips shop
It was twofold really. I did look into it quite a bit and various forums suggested vegi oil. It would seem quite a few others have been refilled with it, with success. I was also concerned that traditional mineral oil would cause issues with the rubber seals used in the transformer. As an aside, it would appear that modern, high voltage transformers, seem to be turning to vegetable oil as a greener alternative to more traditional oils. I do have concerns that it might start smelling like a dodgy old cafe, but time will tell.

Excellent repair work. Congratulations on the successful rebuild of the high voltage can.

Sadly I've only just found your channel, Excellent video. Hope you find the time to make many more of them & look forward to watching them.

i wonder if it might be a good idea to pull a vacuum on the chamber to remove all the air gaps and get the oil to impregnate the core.
Vegetable oil will dry and go sticky. What you need is ISOVOLTINE
