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.
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!!
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
I did simular but cut ring off that pried up so can tack leads to can to hold together makes for quick reopen to replace caps in future just wick leads off side of can and can comes off
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.
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.
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 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.
Your cap must of been an replacement or a production line messup. My cap was not stamped in metal and values where higher then what's on cardboard tube. If have email i can send you the pictures of cap and my modification to make taking can off easier.
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!!!

Good job yours was a challange mine was working on original parts when got it. Just replacing caps not the main can cap.

Glad it helped
Thanks - a great practical approach to this great radio

A good solution but not as clean esoterically as I would like.

@@hestheMaster going to pick up a couple of direct to line led bulbs tomorrow and see how that does.

@@chrissytaylor5690 Yes I did get the kit restored the radio chasis and case. worked great. Sold it after I got an offer I could not refuse.
Consider getting battery powered lamps that run off of car battery. It's what I use when I have to eliminate noise.

it ought to be quiet without all those bumblebees buzzing around in there.
radio techs say those selenium rectifiers stink bad when they go out.
I've had a few go bad on me in the day, back then we had new ones to replace them with.
Would you be interested in repairing one?
Is it in good shape physically?
Always refer to schematic for true values.
Schematics are sometimes wrong, production changes etc, etc. Seen it many times.

I completely agree with you on that. I have been trying to slack off on the yacking some.
