Hi All,

Here's a new project, a Panasonic R-1837, dated by Radiomuseum at 1965.

I saw it on eBay for a fairly low price, the Tuned RF Stage feature along with dual speakers made it worth a minimal bid from me. The typical Panasonic attention to detail shows up in the metal extendable carry handle, with very solid metal snap up arrangement, works like new.

Radio arrived looking quite a bit uglier than the seller photos. I have found that most sets actually arrive prettier than the photos as the cameras tend to accentuate small flaws. This one, not so much. :(

Aside from a lot of paint spatter, there are several areas where the cord plastic melted imprints in the case,

Performance wise, it was a pleasant surprise. The sensitivity is really good as is the full sound from the dual speakers. Nice DXing toy.

The damaged cord needed replacing requiring a splice near the transformer. (Transfoermer housing is riveted to chassis, and will stay that way.)

The dial scale was bent as if the radio got squished in some earlier servicing snafu. Easy fix.

The varicap, triple air type, sits crooked on the chassis due to tension from dial string. Left as-is, not detrimental.

Spent some time removing paint specks, then rubbed out with 000 steel wool, then Armor-All. This removed 95% of the paint and left a presentable appearance. The cord 'melts' are still present but not noticeable.

The dial window cleaned up nicely with Novus 2.

No alignment tweaks were made as the set works pretty well right now and I dont have any documentation.

Overall, I'm very happy with the outcome, much better that my initial impression.

Several photos follow.

Tim

Man, Tim---that turned out great ! Really like the tuned RF-amp stage and the fact they let you know it's there. Looks like it has that "luggage" style---ready to travel. Well worth your effort and saving from the "cabinet" !

Thanks John.

Today I tried connecting my attic wire antenna. It was too much gain for my two daytime stations, anxious to see how the additional antenna works for nighttime DX.

I'm glad I decided to tackle this one, it was a pleasant surprise.

Are you taking a summer break from your radio emergency clinic?

Hey Tim,

Not really a break, just busy replacing the sliding doors on long radio room closet with a set of used French doors (with no frame) that I bought locally on FB Marketplace to make a large closed-in display area. Long story with multiple challenges, so will post this project along with pictures when complete. Just waiting now for paint to dry completely so I can install hardware and move forward...

Neat that the radio has an external antenna connection, curious on how well it will do...

John

A very interesting example of an unusual Panasonic. Congratulations!

Thanks for the nice comments!

Unfortunately, the external antenna hookup only raised the noise level - significantly :x

My attic antenna has been a poor performer, need to get to work on an outdoor random wire. I've got trees, just haven't set aside the time to do the project.
