 Unknown out-of-the-console radio #2

This is the first of 2 radios which originally came in a console, but were on their own by the time I received it.

I imagine they would be worthless, the spare parts being more valuable.

This radio came without a dial glass, and missing some valves. I worked out what was needed, replaced a few caps and it worked quite well, and loudly too. However, 15 years later, it no longer functions, so a recap will be needed. I think one of the old electros has shorted. Is it worth doing? Probably not.

Valves: It came with 6SK7GT/G, 6SQ7GT/G, 6V6GT/G. I supplied a 6AN7, a 6V6GT, and a rectifier with no label, which looks like a stubby 5AS4. I imagine it originally had a 5Y3GT.

The tuning capacitor has 2 large black plastic drums, one goes to the tuning knob while the other moves the pointer. This 2nd one had a broken dial cord which I replaced at the time.

The power transformer is massively thick. There's a serial number on the back with the ARTS&P sticker, and no other identification.

Any ideas?

That dagger-shaped dial pointer may provide a clue.

And I find those metallic push terminals unusual.

I don't think this is out of a console, rather I feel it is out of an early 1950s radiogram. I had one of these chassis which I wrecked from a radiogram with a very poor cabinet. I remember the dial pointer and the odd way the two dial lamps are oriented.

The control on the right looks like it is for MW-SW-Gram selection. It probably throws on one of the dial lamps to light up the short wave dial markings too.

The brand does escape me but if I recall I will mention it here. I am thinking Precedent or Operatic at this point in time.

The knob won't be the original.

A valve a day keeps the transistor away...

A radiogram is a distinct possibility. Should be able to discern if any of those are pick-up terminals.

Looking at the back photo, The left-most is the antenna, then the 2 around the 2nd IF are the pickup, then the 2 around the speaker plug look like extra speaker terminals, and the little 2-pin socket at the right... not sure about that, it might be disconnected.

...And a flywheel on the tuning control shaft. Great for whizzing around the dial!

Decided to do a quick repair.... first thing to do was to check out the rectifier. It had shed most of its filament and the white bits were gathered around the pins, causing all kinds of sparking. I replaced it with a 5AS4 of which I have several.

Next was the replacement of 2 electros, this got the audio part working, but no reception.

A few voltage measurements revealed the 6AN7 anode only had 0.9 volts, so out came the 1st IF transformer. Luckily the break was immediately obvious, right at the anode terminal, the addition of a short piece of wire fixed that.

After reassembly the radio roared into life with enough volume to wake the neighbourhood. I checked out the shortwave bands and found it can tune down to 2.4MHz, and it's quite sensitive too. Not bad for an oldie with mostly original parts.


The controls (left to right): Tone, Volume, Radio/Gram, Tuning, MW/SW1/SW2.
