Does any one know the values of these capacitors? I do not have diagram of radio and need to know values or close to. The numbers on them are 38107,30121 and the last one has two numbers 3511 and 58111 any help would be great help.

Thanks Mike

Hey Mike - 38107 is .25 at 200 volt 38121 ? is .10 at 400 volt - the other numbers are unfamiliar to me. Give me the chassis number and trace the connection back to another component or two and I'll see if I can figure it out.

Thanks for the info. Is there a chart of info where you can find the cross refernce to these numbers?

Not that I've ever found! This brings back memories of tracing every component in a set when I was in my early twenties when I was still in college - some of my first sets were Deforest Crosley's - all I had were photocopies of RCC's from the library - and the only markings on the caps were the Autolite numbers - the schematics only gave the value. There were no layout diagrams. The only way to figure out the value of the cap in the radio was to identify each one by tracing out the circuit - looking back it was probably the best thing for me - since I started from scratch - I had noone to teach me - I learned to identify all of the components and how to trace out a circuit - and since a lot of the radios had altered wiring - it made it even more interesting - but it was great - lessons hard learned are not easily forgotten !

- I've pieced my info together from servicing a lot of Rogers ,Deforest Crosley and Majestic radios over the years. Unlike the RCC schematics - the Original Rogers service manual has parts lists that show the part numbers - Ed Kraushar has scanned Rogers volume 3 and its available by purchasing his CD's - along with a lot of other good information. (volume 3 covers 1937 to 1942 - if you have a 6m531 or 6d531 etc. its from 1936 - but the later years used Autolite caps too - and you can find the values by looking at the parts lists in that manual - sometimes you might have to check the schematic as well - for instance the parts list might say c22 38107 - but no value - then you have to find c22 on the schematic - and beside the c22 it will give the value - say .25 - no voltage in that case - but if in doubt use a 630 volt - they're not that much more expensive these days.

Thanks for the info. I am going to go though some other diagrams and see if I can make up a list of some of the other values. If I can put anything together I will try and post. I know what you mean I had another radio I had to trace the wires to figure out values. I was just hoping for an easier way.
