Hi All, Well I got my hands full with a 1938 Westinghouse model 1038 floor model from Canada. Been working on the cabinet because the radio does work, so I figured I'd start on the cabinet which has several structure problems on the curved front sides. Hadn't been able to due much to it due to the heat it has been over 110 in the shade for a couple of weeks now and I have to work outside under a tarp.
But anyway I started on the chassis the other night and I got to say those Canadians didn't make it easy to replace the caps on such a big chassis.LOL
The thing that I'm writing about is on the schematic the electrolytics are called wet. I'm thinking the new style electrolytics should work fine in there place. What are your feelings on this? Thanks Again,
George T.

The new style capacitors replace the wet ones perfect.

George:

The old style wet electrolytics actually were wet, In other words they were filled with an oil that would evaporate over time. If you look closely at the ones you have you may see little holes in the top of the electrolytic cans. These allowed the units to breath but also let the electrolyte evaporate.

What I usually do with these is disconnect them but leave them on the chassis to avoid a gaping hole or holes where they were mounted. Then I wire in replacements under chassis.

In some cases I open the cans and remove the innards, leaving the post on the bottom available to wire on the replacements under chassis.

NEVER try to reuse the wet units. They will ALWAYS be bad and may even short and cause more havoc as is.

There never was any oil in electrolytic capacitors. It is a water-based paste. The new ones still contain a paste, but with much less moisture. New caps will swell or burst if overheated.Here is some further info:

Thanks Rich

I stand corrected. In any case the old units dry up after awhile and become useless. Thanks for the article - a nice read.

Thank You All Again !! This was the first schematic out of a couple hundred that said Wet Electrolytic and being the radio was from Canada I thought I missed something along the way. Yeah who ever worked on it in the past removed the cans and left those big gapping holes in the chassis. Luckly I had a couple duds lying around to fill the holes. They had smashed in the dial scale, it was in a thousand pieces. I contacted Radio Daze and John in the graphics deptartment was able to make a replacement dial from scratch and it came out GREAT it really couldn't have came out any nicer. I have yet to even find a picture of the radio online, I don't know how he did it but he went above and beyond. Once again Thank You All So Much, George T
