Hi,guys! I need your help as usually: I pick up nice on e-bay nice radio Airline AM/FM and radio works fine, but FM only, it has very low sensitivity on AM band. I could not find any info related this radio. Please have a look at the pictures below and help me if you can.

Hey Vlad, nice pickup.

Looks to be a good half dozen E-Caps, including some with double values, so I would commence changing them out, as the first order of business.

Odds are that that, by itself, would increase the set's performance to near new standards.

That is a nice radio. Were you looking for a schematic??
If so, can you post the model number? - That would help.

I'd do the usual as Fifties has noted. New electrolytic caps all around.
Should perk up to new performance again. Quite possibly the electrolytic
capacitor tied to the AGC has failed and is giving poor sensitivity.
I'd probably leave the IF cans alone since they're still factory sealed.

Wouldn't hurt to clean the AM/FM switch with a little isopropanol alcohol.

Is there a model number? It will start with GEN followed by a 4-digit number.

Hi,guys! Thanks a lot for your friendly support! It was first step only, I did not yet dismantle this radio, may be it has chassis # on PCB backside. Unfortunately, there is no exact model #, the rest you saw at the pictures already. Recapping will be done, of course!

Looks like a GEN-1427A. The schematic is in TSM-79.
Unfortunately, I don't have that copy. :(

Almost five years later this project was successfully completed. It was not required total caps replacement. two caps was replaced as showen red colour at the schematic fragment below.
Airline Gen-1427 works fine now: https://youtu.be/2hvX0AR5DIk
Thanks again for your help colleagues!
