Old Zenith 5S-29 tube radio. First turn-on after repair and reception quality testing. Demonstration of the operation of the budget 5-tube Zenith 5S-29 radio with the famous unique round "Zenith" super-functional scale of one of the leaders of the radio industry, the American radio corporation Zenith.
This is only the first test turn-on, a full review with an analysis of the design features will be soon.

Good radio.
I bet there was a lot of veneer fixing.

[RadioSvit]

Yes, Michael. But strangely enough, I managed to keep the original veneer. I must admit that I don't really like it, so as soon as the weather permits, I plan to either tint it a different shade or replace it altogether.

A little bit of positivity in our feed... My new video about old radios...
Old tube radio Hallicrafters TM600C. First tests after repair.
This is a very interesting model of an all-wave universal portable battery radio from 1952 from a very creative American company Hallicrafters, which specialized in the production of high-quality receivers for radio amateurs and on order of the US military complex for the army and navy. This model became Hallicrafters' answer to Zenith and its all-wave portable model Transoceanic, but in my opinion it never managed to surpass its main competitor. This is only the first video of the first test after repair, in the following I will more popularly consider and describe the advantages and miscalculations, as well as interesting design features of this radio receiver

Peter;
I can't say for certain but many North American made radios from that era, the late 1940s onward, had silver mica capacitors inside the permeable tuned IF transformers, that would fail over time. There were two ways that they could fail, both related to the way they were constructed, one was silver migration, as you can see in the thread Ed posted about the Zenith H-725 AM/FM set, the other issues was a poor or intermittent connection between the silver layered "plates" and the the coils. It was not a very good way to construct these since silver tarnishes if exposed to the air, and can also migrate to the other side since there is a high DC voltage potential between the two plates. I was thinking that this may be a cause for the poor performance of your Hallicrafters, the selenium rectifiers can also become tired resulting in low B+ voltage, and poor performance as well.
Hallicrafters, being a manufacturer of communications receivers, designed, and marketed a number of multi band portables, such as the TW-500, TW-1000, and TW-2000. I do not own any of these models but I have a Sears Silvertone portable that I suspect may have been built for Sears and Roebuck by Hallicrafters as it also uses a turret style bandswitch with the mixer-oscillator and RF amplifier tubes mounted on top like a TV tuner.

Arran, thank you very much for sharing your experience again. I will take this into account when I do the alignment of the intermediate frequency amplifier circuits and all ranges next week. I am familiar with this problem of silver capacitors, because they were also used in Soviet radio engineering.
As for the Halicrafters receivers, strangely enough, they were quite popular in the Soviet Union and had great authority due to their high quality. A lot of Halicrafters and Hammarlund receivers were imported to the Soviet Union under the Lend-Lease program during World War II, but stationary models, such as the SX-28. They are still sometimes found at our local auctions. But the TW 500 models.... I have never met the TW 2000 in Ukraine. Perhaps because they were manufactured during the Cold War and were no longer supplied to the USSR ...
