These were all the rage when I was young, but most sounded very boxy of
course.
I remember our first home made mono one made by my father which you could
keep u your meal warm on as it was valve as well.
The fm/am tuner was switched to give all the stations you needed, IE
Luxumbourg and the bbc ones and a couple on fm, it was third program
mostly.
The record player was a bsr changer with a ceramic turn over needle amade
of saphire, which meant you wore them out in about three months.
One big WB speaker in the front and there you are it had bass and treble
and hummed when you put your hand neear the controls, so you could always
tell it was switched on withoug touching anything.

Was equipped with two aerials, one which ran over the curtain rail for FM
and a bit of wire under the carpet for am.

Later on it was added to with an input from a 405 line tv sound input and
this came from an old projector which showed programs on the wall above the
radio gram suitable painted white. The snag of course was that the bit of
the room from the projector, looking like a table, and the wall was a no go
area during tv watching hours.
The tv itself was supposed to be a back projection system, but it had its
scan coils reversed for this job. I'd imagine I got plenty of x rays off
that thing with its oil filled tripler and loud whining timebase, but we
never bothered with trivia like that back then.

I used a Mullard MW 6-2 as a ray gun in the fifties, 25kv and
2.5" Dia, plenty of x-rays produced.

not sure if your reader can interpret this web page.

A long time ago I acquired one of these complete with optical assembly
and coils, and since the voltages appeared to be similar I connected
it up to the relevant feeds from a colour TV chassis. It worked quite
well, and could project a huge if not particularly bright or sharp
picture on the wall. If only I'd been able to get another two of them
perhaps I could have had colour.

my parents had a lovely one - a proper piece of furniture.
i recall it sounding fantastic but chances are it didn't.
had one of those 'stack 7 singles to play in turn' record players and a
long radio tuning display that was about 24 inches long, it glowed in a
lovely orange when on.
sadly they got rid of it many moons ago - almost wish they had kept it
even if not for practical use.

Well I still had some of those Mullard projection tubes until quite recently
but the light box went when I discovered how good the mirror was at
lighting fires.

No don't ask.

That was done back in the70s by some misguided person as I recall. Rather
large device though.

That lens in the front was made of some kind of gel I think.


I also remember two things from those heady days of the 60s, we had a rat
in the tv once which was being chased by my granny, and one day I switched
it on and there was an almighty bang and bits of smelly silver paper went
everywhere.

Ah yes dials, I used to like dials. a Dynatron radio was actually multi
coloured but it was only coloured paint on glass and cunningly designed
optics. Had a motorised tuning system for its presets, so the pointer moved
and you could hear it tuning when you pushed a preset. Very cunning and also
very prone to get stuck when it was older!
Sigh.
Strangely the cheap bakelite dropper run radios went on for ever even with
the huge blister in the top where the dropper cooked the cabinet.

Those things were lethal as the chassis was live and the aerial simply had
a capacitor between the terminal and the live set inside. Elf and Safety was
a bit naff in those days, yet none of us died despite regular belts off the
devices, Heck you could even pay for a shock at the amusement arcades and
get your feet s rayed in shoe shops back then.

I have seen one with a 78rpm motor (and a + or - slider for some
variation but it certainly didn't get down to 45rpm) and a head
containing magnet and coil which took a steel needle held in by a screw.
It had an autochanger which could hold about 6 records, but unless
extra long play needles were used, you couldn't play 6 sides without it
going too blunt to be nice sound.

Up until the age of ~10 our house had DC mains, so I had various
ex military rotary transformers setup working in reverse to get
12, 28, 150 volts. When the mains was changed to AC, they
foolishly left all the old meters outside the houses for
collection.......I ended up with about 6 2lb jam jars full of
mercury.

My parents had a wonderful PYE unit, again, a real piece of furniture,
with vertical spaces each side of the speaker box at the bottom for
records to be kept vertical. Each side had a door, too. The Tuning
Scale had several short wave bands, and wonderful names like Hilversum,
which were exotic to a young lad.
I removed the chassis and turntable and took them up to university with
me so that I had a way to play records. I was very careful to unplug it
each morning so that the cleaning lady didn't electrocute herself if
she touched anything, as it was totally exposed. H&S would kill me now.
This was a few years ago.
