Hallicrafters S-38 E Final

The radio she is finished...

I decided to paint the cabinet since it had a few rusty spots inside and out. The grey Hammer-tone is a little darker than the original. I masked off the control panel to keep from having to re-do all the control knob lettering, and logo. Some time in the future I will get the hang of water-slide decals and do a proper job. The front glass was cleaned with denatured alcohol. I cut new rubbers for the bottom side of the glass out off out heat shrink tubing. ( gives the glass to metal a little cushion) The old ones were dry rotted. The S-38 series  radios were made between 1957- 1961.

The speaker needed serious help. It was very dry, dusty and I could see light through the cone! I did a little trick one of my Elmers showed me once. I sprayed the cone with clear enamel spray. 3 light coats and  it stiffens the cone up and makes it a little stronger.

This is the same original speaker. They make a commercial speaker cone paint (like with a brush). I like this cheaper method, fast and easy.

That's it for this old radio. I am on the lookout for a better knob set. If you really want to go first class you can buy or make your own bottom and back covers. Labels, you can get a copy of those too. Stain them with a teabag and it will look like the original labels! This radio is going to my night stand. I have an antenna already there for a short wave set.

A couple of videos showing the S-38E.

This one is AM band playing.

S-38E on 40 meters.  I decided to go ahead and paint the chassis since I have grey Hammertone paint. More to come...

Hallicrafters S38E

I picked up a nice little Hallicrafters S38E over the week end. This is one of those "it lights up but it hums" radios... I always ask what was it humming? ( I usually get a go to you know where look) :)

Here it is out of the chassis, mostly dusty.

There are 5 miniature tubes in this receiver. The dial string is in excellent condition so it will stay put.

 A look under the hood. A few black beauties to replace not too hard to get to either.

Interesting mod done this this receiver. I am guessing the 25 MF section went bad so they cut the blue wire and added it externally.  Probably would have been safer to use tape or heat shrink tubing on it rather that just let it float around bare.... The orange cap was substituted for one of the black capacitors.

All the caps are now replaced with the proper caps and heat shrink tubing applied where needed. Total time one and a half hours.

If you can not receive CW on your S38E, here is the fix. The grey pointer is on what is called a "gimmick". This one is formed when the brown heavy wire is twisted with one and a half turns of wire one end is on the IF CAN and the other is on the IF tube pin one. The brown wire snakes through the IF CAN and into a metal tie down. Remove the tie down, unsolder the short wire connecting these points and add one long enough to make 1 and a half turns around it. Keep the brown "BFO" wire in the IF CAN area and make it come as close as possible to the IF tube socket.

When you need just a couple PF of capacitance twist two wires together, for every inch or so you get a couple PF of capacitance.

This is what the brown wire "BFO" should look like on this end.

Between the next IF CAN and tube socket you will see a green wire. This one is long enough to unsolder and wrap around the heavy brown wire. Look back at the under chassis picture above  and you will see that it was wrapped onto and back under the brown wire. No good, it needs to go one and a half times around your "BFO" wire ......would this be a FAUX  BFO??    :) Sorry.....
