I have looked everywhere and I can’t find this schematic.
The actual radio tag is GE M53 but I have searched and found that this [WR35] is the exact same radio
I can find photos of it on the internet , but no schematics
somebody please help me .

Does this info help maybe? https://radioatticarchives.com/radio.htm?radio=6785April 7, 2020 at 6:34 pm #13712Alistair ThomsonCVRS Member
I found this:
but I know nothing about these guys or how reliable they are.April 8, 2020 at 12:43 am #13719
Some GE radios were made by RCA . The k-53 was made by RCA and this rca 110 should be the same pending the K and M models are the same,

Sterling has hit the nail on the head, and explained a confusion I encountered when trying to find the K-35 yesterday. I found what was billed as a link to the schematic of the Westinghouse, but it turned out to be the schematic of the RCA 110, 111, 115, 100 and 101. So I didn’t respond to this thread with that, assuming the usual regarding internet links :).
I have attached the image I found, but Sterling’s link is more comprehensive.

About a month ago I recapped a Victor [RCA ] model 115, and I thought that this GE M 53 would be the same,configuration.
They are not the same.
Here are some photos showing the model 115 [the recapped one ]
and the GE model M53.
If I could read the values on the caps I could do it , but they look like pieces of tar wrapped in paper.
The transformer on the one that is recapped is 25/60 [larger one]
As you can see, some of the parts look the same but with the resistor board, they are quite different.
The recapped radio is the Victor model 115
I have tried everything I can think of the get a schematic, and I have seen photos of the WR 35 and it is the same as the radio I have , but I can’t find the schematics.

They look close to me other than resistor board. In doing my research I came across a ARF discussion that a guy said they were the same . Does the caps on both radios connect to same locations?April 8, 2020 at 12:33 pm #13733
Sterling , I agree with you in that they look the same, but I have looked at various parts comparing both radios and I don’t see some parts as being the same.For example I have a couple of resistors in the 115 radio which are not in the other one.
the original; model 115 had a large 4 MF cap in it and the other on does not,
I am trying to compare schematics of the model 115 with the other radio ,but it is very hard to see where some of the wires go, especially under the resistor board.
I might have to remove the resistor board. Someone has put in a couple of large caps in there so I don’t know exactly what they should be.
I presume that no one can find the schematics for this and the post will just fade away.
I hope not , but I feel like I am up against a brick wall on this one.
Thanks for looking and if you find any more information let me know

I will keep looking. Did you post on ARF? Also could you post a picture of tag.April 8, 2020 at 5:38 pm #13735
Also I found out Beitman 1926-1938 page 179 info shows this same rca chassis under there listing for Westinghouse wr-35 .April 8, 2020 at 9:16 pm #13736
Sterling, I have the riders books but not Beitman. Maybe you can tell me where I might find this information.
Thanks for digging around. I did post on ARF and tomorrow I will post a photo of the tag on the radio.
I took off the resistor board and did find one totally broken 14 k 3 watt resistor.
I think I am making some headway , but with the proper schematic ,it would be a lot easier, especially with my limited knowledge.

Here is the link to the link , the index in the front shows the Westinghouse wr-35 on page 179 and also I think the majestic r-131 chassis might be there also .

Thank you Sterling;
It does not surprise me that the page 179 shows the models 110, 111 and 115.
It is surprising that the listing tells you the model WR 35 is on that page , but when you look at that page, you don’t see any reference to
the WR 35, only the victor models 111, 110 and 115
It does look like the model WR 35 is the same, but the components are arranged quite different
I have the model 115 and it is different, but maybe they just changed the components around, adding a resistor board .
Now I see I will have to go through every component and check every part of the schematic on the 115 and see if the same components are there [but in different locations].
It is possible that someone had added a resistor or two, but I will stick to the schematics.
For example, there are three caps rated at 10mf in the radio and the schematics for the 115 call for 4 mf, but someone had added these later.
I guess some people just put in any cap they have lying around, even if it is three times as large
Here is a photo of the tag on the radio.
Well I have a lot of time at home so I guess I will learn something mode about these radios.
I will keep plugging along.

I hope i was of some help . Is there a chassis number somewhere? I think it was made by rca and components are just rearranged.April 9, 2020 at 10:48 am #13742Les DicksonCVRS Member
Hi Dan. In the Manual of Most Often Needed Radio Diagrams 1926-1938 it lists the Westinghouse WR-35 in the index and indicates that it’s on page 179. On page 179 it shows the schematics for RCA Victor 110, 111,115 and RCA models R-100, 101.
The quality of the page isn’t good for the RCA Victor 100, 111, 115 but it looks like the tube line up is 58 2A7 57 2A5 80
For the RCA R-100, 101 the tube line up is 6A7 6F7 41 1V
If either of these seem good, there are schematics available at radiomuseum.org.
