TV radio & record payer in one cabinet?

Was anything like this ever made or imported here? TV radio & record payer in one unit.

http://www.youtube.com/watch?v=zd4Su...Bgg98q-_IVuIFA

This is a "Belarus 210L" radio, TV, record player, made in the USSR probably late 60s or early 70s.

I found this after finding a video of someone repairing an old russian Televizor KBH-49 made in 1956.

This is obviously a much later product, it uses more modern "all glass" valves and printed circuit boards. If you stop the video at 1:22, there is a view of part of the circuit, but what is the mysterious component to the left of the 6P31S valve, it looks to be a diode with an anode and no cathode (?), there look to be 2 diodes on the same page.

The video is mainly pictures of the chassis until 6:30 where the set is shown working and the turntable can be seen. There looks to be a rather nasty picture fault around 5:15

I'm not an expert on reading circuit diagrams, the valve types do look familiar but the USSR did "acquire" a lot of western technology so they could be identical to types sold by "Mullard", "Mazda" and others.

There looks to be a rather nasty fault around 5:15 but after 11:25 the picture looks pretty good for a 40 year old set.

It is a type of voltage regulator, like a more modern zener diode. You will notice the similarity to that in the Russian circuit with the series resistor and the voltage tap off between the two.

The symbol appears on this page as a "Glow-Discharge Voltage Regulator Tube".

Thanks, I hadn't heard of those before.

It's a fairly uncommon old component

I seem to remember Fidelity made a combined TV/Radio/Record Player?.

I wouldn't like to try and place a date on the Russian one, they were still churning out poorly made valve gear decades after everyone else, and the top video looks relatively 'modern' for Russian gear

We sold quite a few Russian radiograms made by Rigonda, the fact they were 30-40 years out of date made little difference, the low cost made up for it

If you look around 8:15 on the video, he is doing something to the tuner. It looks rather like the tuner on an old Ekco 405 line set my parents bought in the mid 1950s.

Unfortunately I can't make out the markings on the radio, I wonder whether it had FM?

Do you have the Rigonda demonstration record http://www.youtube.com/watch?v=YpckRcRSMPY ? I found a mint copy the other day.

This is the demonstration record (in russian) for "Vega" stereo equipment.

I remember them selling radios in this country but not the sort of equipment shown on the LP sleeve.

My F-in-law lived near a TV and radio shop in the early 70s, who would build all sorts of combinations into cabinets to order. I have often wondered if this was common back then or was it actually a fairly unusual practice?

”

Which would probably put a Russian version 70's or 80's

As far as I recall the radiograms did?.

No, I've never seen a Rigonda test record - no idea they supplied such things.

I wouldn't say 'common', but probably more common than you might think - people like Leak, Quad etc. made amplifiers and tuners specifically for building in to your own cabinets.

I had a Leak based radiogram at one time, using valve Leak modules and a Goldring turntable - I presume it was made professionally, as it was an extremely good cabinet.
