I'll keep you informed and a video to follow...

Beautiful fan! I did not knew they could still have the small bell canopy as late as 1981.
I have a Casablanca Zephyr from 1980 that was converted to 3-speed pull chain from the genuine Casablanca 3-speed converter and I consider it original. As Dan said the variable speeds are known to failure at the point that Casablanca offered a kit to convert these fans to make them work again.
The very pale blades are real Casablanca blades but much newer. They are just way too pale to look good on an antique brass fan. The blades on my 2008 Panama II have those little sticker near the bracket tips of the blades.

This is turned into a project.. The transistor in the heat sink is most likely bad, and it's burning out the pots.. I've took reference photos.. The PC board looks fine, hopefully the caps and resistors are too.. It's gonna be a few weeks at least until I get the problem resolved..

I figured as much, if one thing goes out multiple things go out. The board does thankfully look to be in good shape, at least not burned up beyond salvage like the one in my AB Vic is.

I know, I kinda figured there is multiple problems.. I searched the RCA part number and I do get alot of results.. I don't know if I want to go with the same part or another one... From the research I've done, the transistor is faulty.. I was doing a video with the new pot switch describing what I've been doing and up in smoke it goes.. I'll have to put that in the video once the Vari-Quiet restoration is done..

I'm trying to stop you from sinking more money into it.
For some reason, with these, when you replace one component, another goes bad. If you replace the pot the transistor goes. If you replace the transistor, the board goes up in flames. It makes no sense on paper, but that's what has happened to me multiple times, and it has happened to every other collector I've known who's worked on them. All the specs are sound and on paper it SHOULD work but it doesnt. I once sent an entire fan to high end electronics engineer who sent it back to me saying "there's absolutely no reason why this shouldnt work. But it doesnt work".
You can try replacing the transistor. If you can manage to find a similar one with a higher current rating, even better. I think it will end the same. If you happen upon a solution I am sure everyone else will be interested.
The quote was from Home Movies. I thought it was funny.

I never saw that movie.. Thanks for your input.. I'm still going to see if there is a solution, I also have a friend that helps with my antique TVs, who use to be a TV repairman back in the 60s and 70s, so he may be able help a little also.. I'm going to look into the Transistor next and see what I can get.. It took alot of looking to even find a 5k or 10k pot that is rated at 5watts.. At least there is a source for those, though will take some modifying like you were saying about the shaft.... Seems like there are not many companies that make these, that are turn once..

I replaced the transistor with an NTE 162 in a Vari Quiet board I rebuilt, hope that helps

Thanks for the info John.. I'll have to order up a few of those..

Hmmm... how reliable is Fasco's equivalent variable-speed system compared to Slumber-Quiet? If it's any better, has anyone considered transferring the system from a donor Fasco motor to a Casablanca?

From my experience, the Fasco Vari-Low is more reliable. I don't think I've ever run across on that had a bad Vari-Low system.. As far as one being transplanted into a Casablanca, I would imagine it could be done, though probably with a little rigging up.. Would I do something like that. Probably not..

I dont have any donor Fasco motors. If I did, I'd make them into Fasco. I hope others would too.
Fasco and Emerson systems, I've never seen one fail, but the Emerson system is noisy, and the Fasco doesnt go slow enough for me.
The Lasko ones fail. Who else had 'em?
I cant think of one of these "heat sink systems" that I actually like. The Casablanca one is best WHEN IT WORKS. When it starts to fail, just scrap it and start over.

I wasn't aware that the Lasko system was prone to failure. I've had one for years without any problems.

All the Lasko's I've found have the transistor shorted. I dont think I have any that function.
