Been working on this and got it going about two weeks ago.
The send and received switch was broken, i was told that before i brought it.
I order a switch and put it in and now the switch is working like it should.

Now here my problem? The second am band 1.32 - 3.2 makes on sound.
Also the first sw band 3.2 - 5.7 does the same thing nothing.
All the other bands work great.
Went over the band selector contacts 3 times and still nothing on these two bands.
First two time I spray deoxit on them and rotate the selector back and foward.
The third time I used a small brush dip in deoxit and went over all the contacts.
Still nothing on these two band?
I have also clean the tube pins and the sockets without luck.

Any suggestions where to look?

If it were mine, I'd try to see if it responds to an RF signal generator set midrange on both bands. If so, the bands are probably just temporarily "dead" due to the various environmental factors that affect shortwave propagation.

If not, I'd first suspect the antenna and oscillator coils that are switched in for these two bands. An open winding will kill the band. An ohmmeter will tell the story quickly enough. Of course, you'll need a service manual for this specific set in order to get very far.

From my library (BAMA's is in .djvu format):

Mistake on pg. 13: the "60 dB" line on the right should correspond to the "10^3" line on the left.

I agree it's probably something mechanical like the switch. I would encourage you to keep looking; focus more on whatever work you did.

Probably not something like a tube pin. Otherwise the whole radio would be affected, not just one band

Good news, She alive and well.
Thanks lorenz200w for pointing me to the oscillator coils.
I check them with a ohm meter and both was good. But, I trace the wire running from the oscillator to the band selector and noticed that on both of the bands a contact was not making a good connection.
Took a wood rod and push the contact in just a little bit and she came alive on all bands.

One last question? Why did this happen? being 60 years old?















good news

The question is also the answer. Who knows how many owners have been poking around in your
radio's innards since it was new?
