Having to find things on our own helps fight Altsheimer's. For many of us, old farts, it is a useful brain exercise. Now that troublehooting (I am leaving that typo uncorrected, like it) has become familiar routine and no longer poses enough challenge.

Acked, but there are so many people out there who do not want to search on their own (and I do not necessarily count myself among that number).
I therefore try to be a good host.

Thanks Ron for those links.
I'm not one for tooting my own horn.
I continue on in Part 3 removing the large condenser can.
I like to use humor in my videos, as this country needs all it can get nowadays.

Hi Buzz
Saw your videos and had a couple of comments. Your set has no electrolytic condensers in it power supply or elsewhere. All of the condensers are paper or mica.The filters in the P/S are paper and as paper condenser are they are non polarized. Do not replace them with electrolytics as they can't take the high ripple current and will short after awhile (like a month or 2 with daily usage. Ask my model 87.
You mention that the label is riveted to one of the IF cans. Cant happen. Your set is a TRF set not a superhetrodyne. Superhets have IF's TRF's don't. The TRF sets use a number of RF amp stages, a detector, and then a power audio amp. No frequency conversion like a superhet.
On removing the filter condensers in the metal can you could have saved your self a lot of time and construction of the terminal board that mounts on the bottom. By placing the filter can once removed from the chassis in the oven in a pan under it. Heat it to 175-200 degrees for about 30-45 mins. This is enough to soften the tar. Gently lift the terminal board just enough and cut off the wires that hold it on. Carefully pry and use a cork screw or an Ihook to remove the remaining parts in the can. Replace the original caps with 630V paper (mylar) units.
Pls not miss understand my post. Just wanted to clear up a few bits of info in your videos. I'm not trying to degrade or discredit your restoration. Just want the newbies to get the proper info.
GL with your project. Looks like a fun one!
Terry

Hi Terry.
I know its a TRF radio. I just misspoke IF instead of RF
The boiling was done for comic effect .( hoped you enjoyed that bit)
As for the caps, you are right...another viewer commented on it. I will address that in part 4.
I like to throw in a bit of humor and silliness into these videos.
Thanks for watching...

nice series Buzz!
Thank you for being a gracious Host, Ron.. I do a lot of searching... most of the answers I'm looking for are in the archives but I try and strike a balance between lurking and participating. sometimes that means asking a question you know you'll find the answer to eventually.

I can't comment on the potential ESR and ripple issues with using electrolytic caps in these sets, but one thing they will not have is the longevity of poly film capacitors no matter how good the electrolytics are. Most of the filtering is handled by the choke and speaker field coils in these sets which removes the AC ripple current very well. The reason why later sets went to electrolytic capacitors was due to cost, they could produce capacitors with a high value that were compact and inexpensive, especially in relation to filter chokes, that brought the same results and allowed the manufacturers to make the sets cheaper and sell them cheaper.

Arran
