Some time ago I acquired a model 2262 with a blown speaker transformer and it required the usual work. Someone made a thread on one of these at https://vintage-radio.com.au/default.asp?f=4&th=12.

About 2 years ago I obtained the low-end version of this radio and when I got it home found that most of the parts had been disconnected, removed, or replaced with odds-and-sods. It looks just like a 2262, but it only has 5 valves and no tuning indicator. Does anyone know what model it is and where a schematic can be found? I'd like to try to revive it if possible.

Thanks.

Any clues as to original valve line-up?

Also, live chassis or mains transformer?

Check out all the Philips models starting with 22xx.

The first two figures in the model designation indicate the cabinet style. In this case the bakelite cabinet style is type 22.

These models were produced just prior to cessation of radio manufacturing due to the war. There could be a war time economy model with the type 22 cabinet where the service information is hard to find.

The 33xx series had a similar style bakelite cabinet. You also might want to check out these out as well.

GTC, I don't know for certain, but I think it's 5Y3G, 6V6G, 6B6G, 6U7G, EK2G. Mains transformer.

From the outside it looks EXACTLY like the 2262 in the linked thread. It's just inside that is slightly different:

- 5 valves instead of 7 (no RF amp, no magic eye)
- 2 gangs on the tuning capacitor instead of 3
- extra light for SW band is not there
- mounting for magic eye is not there
- presumably less interstage transformers etc, but that's part of the destroyed area.

The 2262 in Brad's photo has been hacked, with extra terminals and a switch visible in the rear view. Those things don't exist on my 2262.

The model designation for this radio, if it has short-wave, should end in 52. You'll probably find that most of the xx52 Philips will be similar electrically. There is plenty to be had in the AORSM's or Kevin Chant.

Thanks, the xx52 was the clue I needed.

The schematic and chassis layout of the 2652 looks pretty good. The only thing is the 2652 only has 2 knobs, where mine has 4, but that can be sorted out later. The vandals even removed the band switch and replaced it with a disconnected and loose potentiometer.

Wish me luck with this!

The thing I really detest with this Philips (and the 2262 and some others) is the tuning cable that always gets jammed. I find that after a bit of tugging it can be freed, but after being left for a few months it jams again. Is there a proper solution to this?

That's a pretty common line-up for Philips of that era but I cannot find a set with a 2-gang tuning cap.

I note classified ads in Trove in 1939 stating 17 models of Radioplayers from which to choose, so there must have been quite a few variants out there.

Looks like 2752 may be the one, but even its diagram shows a 3-gang tuner. It's very unusual to have a gang for MW and another for SW, but that's what the diagram shows. The 2262 has one gang for both, like most radios. I think I'll copy the 2262 up to the grid of the RF amp, but instead connect this to the grid of the EK2G. Hopefully that should do the trick.

The pictured radio has excellent sound and tone, or at least it did the last time it was used which was a few years ago now. It will be up for sale in the next week or so however it is too big to post so the lucky buyer will need to pick it up from my storage unit in Gladesville, NSW.

I priced those units a few years ago and was horrified at the rental prices. What a racket! It's money for jam.

I decided to buy a unit instead.

I priced those units a few years ago and was horrified at the asking prices.

Don't ring back - the prices now would give you a cardiac arrest and that is why I am about to bail out of it. It's a shame because it is a good place to store. 24 hour access - which not all storage places have, you don't need to check in first and it is very convenient. I've never felt like my stuff was in any danger from theft either. Thousands of $ worth of radios, thousands again in camping equipment, thousands again in tools of my trade and some miscellaneous items.

Anyone who has a few bob in the bank would be well advised to invest in a public storage facility - they are licences to print money. That building and the land could be had for about ten million dollars. You'd make the money back sharpish.

They are definitely priced for short term storage.

After a day's work, this radio is now working.

The power supply and amplifier stages needed to be rebuilt from scratch. The choke had originally just been floating around, unsecured, and what was left of the remaining parts all went in the bin. It was clear that it bore little resemblance to the schematic, so I designed my own.

The tuner stages showed no sign of there ever having been a shortwave section, despite it showing on the dial glass. I decided to leave the tuner wired up is it was, just in case it happened to be a working configuration. Some wires had perished insulation and had to be replaced. All resistors checked out fine, but all the paper and mud capacitors were replaced.

I couldnt find a EK2G so I used a valve marked as "possible 6A8G", and hoped for the best.

On applying power, the valves lit up and some sounds were heard. A small adjustment of the tuning brought in a station. Then the crackling started and I had to replace a mica cap at the anode of the 6B6G, and also replace the 6V6GT. The 6B6G also turned out to be troublesome so it was also replaced. The tuning of the 2nd IF was way out, and the aerial trimmer needed a small tweak. It was now working quite well with the outside antenna.

The next problem was a loud squeal when the volume was turned up. This sort of thing is normally caused by unwanted positive feedback within the amplifier. I eventually noticed that the wires to the speaker transformer (mounted on the speaker) passed not far from the detector stage. I rerouted the wires away from there, and that fixed that problem.

The radio has 4 controls, but only 2 were in use (tuning and volume). The power switch on the volume control was burnt out so the power is connected permanently for now. One of the unused controls was marked as 0.5M ohm, but was in fact open circuit. The other unused one measured about 460K ohm. I thought I'd make a tone control out of it, but the squeal came back so I abandoned that idea. It might get revisited in due course. The amplifier has so much gain that the slightest misrouting of wires will send it screeching.

Now, time to get it back in its case. Being a typical Philips, it took ages, but eventually it was done. Now it has joined my collection.

I wonder if I should try my hand at the web-covered relic of an Astor? Hmm.

Not the original dial glass perhaps? In some respects it seems to be a bitsa.
