Jajaja, It's funny to me that when things get difficult and you don't want the disaster to be seen, you forget to turn on the camera... Even so, your contribution is greatly appreciated, it is a pleasure to restore these giants of old radio. Greetings!!
If you're using standard linear ballast florescent light fixtures there they used to make filters that went between the line feed and the ballast. We used them in hospital settings where transmitted line noise would interfere with sensitive medical monitoring equipment. I don't know if they still make them but would imagine that you could find some surplus somewhere. I think that you will find that the new LED fixtures with their switch mode supplies are even worse noise generators than what you have. Good luck and feel better.
Oh man. Thank you for doing this. I just picked one up. Cabinent needs redoing, But everything else looks in pretty good shape. Your video is what gave me the guts to give it a go. Wish I had your test equipment, so I guess my DVM and solder station will have to do. Wish you had a parts list for the capacitors. They look ok but will replace them anyway. Not sure about the 4 in the can, never did a job like that, and Im sure you can't buy a replacement. (Radio will hum if turned on but have NOT checked tubes)
Not sure if you've already got your radio up and going?.....but I do know on eBay they sell a kit for these transoceanic radios that eliminate the selenium rectifier and the 50al tube. I also found a complete capacitor and diode kit made just for the 600 series transoceanic. And the kit is pretty cheap. Plus has great instructions in diagrams that tell you which ones go where! 😉👍
I listen to shortwave broadcasts and have for the last 60 years. I do some basic maintenance on the tube rigs I have. I recommend setting up a row of interior incandescent floodlights over the bench. They don't crank out any RFI unlike fluorescent tubes and ballasts or filthy LED lighting (which is the noisiest, especially with dimmers). Incandescent floods have another plus: the floods throw sharp edges on your work.
Thanks so much. Very useful as I’m about to attempt a restoration on an A600L. Not many ZTOs found their way to the UK - Tnx Dave Shaw G4NOW -Greenwich London
Word from the wise , you should use incandescent bulbs for lighting in the shop. Get some 1 by 6 pine boards and attatch plastic bulb bases every two feet on them and wire them up . Screw them to the ceiling . Then when secure put the bulbs in . Use 60 watt bulbs. You could daisy chain the boards and have one with a long extension cord to go to a wall socket. Nice one day project. Guaranteed noise free radio aligning.
@@oldavguywholovesRCA You could use bathroom fixtures like the ones over a mirrored cabinet but that could be rather expensive and look rather odd with their bright nickel finished rectanglar box on the ceiling.
I have this problem with electrical noise. The only way I can get past it is with an outdoor antenna. Between the lights and the computers in your shop, you are in a tough situation.
hello found your chnl. and i find your videos are very helpful,, i have a Q where or who do you buy your replacemnt part,, any help you can give I thank you thanks for shareing
Ground isn’t ground. It’s B- . You’re starting to look like a tinkerer rather than a repairman. Excuses, excuses. Well,glad to see you’ve recovered from some mistakes, comes with age. Don’t ask.
B- is still a ground. We all make mistakes and I have been in the electronics field for 40+ years. Been burned out several times in my career, and I have a larger background of experiences to draw on so I don't particularly like your statement. If you don't me or my channel then quit following me and take your negative comments with you.
Hello my friend? if you just cut out like 50% of your bla bla bla bull chit you could have a great video! People want to see you repair old radios not listen to 30mins of bull crap i got this i got that bla bla bla! watch glasslinger videos he/she make great video with very little bull crap!!!
