Don't think there is a blow by blow description on the net. The front end is pretty much the same as the 37-116 and 37-675. The '38 model are similar but have a different trimmer layout. Try searching these models. The general consensus is to remove the dial assy to get it out of the way, remove screws holding the sub chassis, unsolder wires holding in till it comes out while photographing and marking where they went. Reverse to reinstall.

Sounds pretty straightforward; I'll have a go at it some time this fall. Thank you; I'll probably take pix to either (a) show future techs how to do it or (more likely) show them what not to do Icon_smile

Very excited to break into this radio. It's quite dirty and looks like it's been stored for many, many years. Crazy thing about it is it has not been touched, period. Not even the electrolytics have been touched. A quick test showed all power transformers, chokes interstage transformer field coils, etc., good. A nice bonus is the 6B4s appear very strong.
Will be an interesting project, you can do the blow by blow!
With a good robust set of 6B4's I may be able to hear in down here near phily!

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

Give the tuner a good wash in Dawn and hot water. Then set tuner in a plastic container and cover with vinegar let soak ...David — 12:53 PM

If you have rust between the vanes, I wonder how you get the NJ in between, and how you then wipe it off.morzh — 12:02 PM

If the noise is still there, the OPT might just be OK. Or so we hope.morzh — 12:01 PM

You would probably be replacing the OPT.RodB — 10:54 AM

Thanks guys. I think I'll give the Naval Jelly a try since I can better control where it goes.dconant — 09:23 AM

Just forget this number, it is useless anyway. Simply proceed with your project.morzh — 10:08 PM

My $0.02 is that it is a misprint. I tried to look up the value for the similar 84 and 37-84, and ther is no resistance...MrFixr55 — 09:51 PM
