Admiral 24A12 Restoration - part 5 / recapping tutorial

I'm knee-deep into restoring my Admiral 24A12 and I need some parts. Maybe some of my other sets are similar? So, I take a look at some of my other Admiral sets.

Now, I've got my caps and it's time to put them to use. Here are a few pointers on putting them to good use.

These types of capacitors don't contain PCBs so no need to worry. It's old oil filled caps that you need to avoid. Like the big caps on AC motors. Here's a great guide on the subject: http://www.environment.gov.au/settlements/publications/chemicals/scheduled-wa...

those skinny caps look like Nichicon PW series.. long life, high ripple.. great choice for this. i could be mistaken though.. camera shakes all over the place so you cant read the series printing even when paused.. (blurry)

@Knaeckebrotsaege I believe I used PZ series caps. I sometimes use PT series too.

I've been pretty lucky so far and haven't been "bitten" by a CRT.

I thik the worst for me was while working on a Predicta Princess set. I slipped and shorted out the main B+ supply with a probe tip. There was a huge crack and the tip was blow right off! It was a while before I could use a meter without my hands shaking :P

Almost forgot, when I was younger I got shocked off an anode lead in a TV I was working on, and broke the back of the CRT off with my elbow. I was ok, but the TV was a parts chassis after that... At least it was just a cheap plastic modern TV.

What do you think is one of the worst things you've had happen during a repair job?

Yikes! I'm glad you're OK. I've had a small wax/paper cap blow up in my face too. Scared the crap out of me. Luckily, I only had a small cut from a metal lead that grazed me.

Luckily I haven't had any bad experiences with the large oil caps such as the big oval shaped motor caps, but I did have a small oil cap explode on me once. It was a ceramic cased cap that was used as the "across the AC line" filter cap in a TV. I was ducked inside the back of the set making adjustments, when the thing blew up in my face and shot nasty hot oil all over me... It was a nasty green oil too. Good thing I wear glasses, or I probably would be blind :-)

LOl - good point, but don't worry - electrolytics don't contain PCBs. It's old oiled filled caps you need to avoid. Like those used on AC motors. I updated the desription of this video to include a link to a great guide on the subject.

That's pretty cool, though I was never brave enough to open any filter caps... Too afraid of finding PCB's by mistake :-)

And I agree, Orange Drops are the best. I use them whenever I can.

Thanks!
