Hello again from Jimb. Hoping someone may be able to identify the model of this little Phillips mantel radio. It has 4907 stamped on the back of the chassis cannot find any data on a 4907.
The valves are EBF35, ECH33, 6V6, with a 6X5 rectifier. It has quite a small tunning gang mounted on its side. The IF cans look strange like oil filled capacitors they appear to be non adjustable . The tuning dial is small and rectangular not unlike the 1947 STC bantam the back section of the dial is red plastic. It looks like late 40's early 50's
I have taken a photo of it however I don't want to bother Brad for an up load.
Kind regards.Jim

Most likely a Model 100 or 100A.

A very desirable & collectable radio.

The line-up and the small rectangular tuning dial matches the 100A mantel:

Maybe a photo or two would help here.

Thanks Monochrome and GTC.
I was not wanting to bother Brad with uploading a photo.
I think I should have that circuit. It is a total mess the power transformer has broken windings and will need to be replaced with something .
Regards Jim

Thanks Monochrome and GTC.
Yes it appears to the Phillips 100A. I am now in a quandary . This is not mine it belongs to a guy Tony Hardy . He inherited his Dad's house full of old electronics I have repaired a number of his radios over the last few months just for something to do. This radio is a mess Monochrome you mentioned it is highly collectable. Should I just bundle it back up and let him flog it off on eBay it is the standard brown Bakelite model.For protection I removed and covered the speaker so it will not be damaged apart from that I have not as yet touched it.
The power transformer has broken wires hanging out of it and will need to be replaced. That is the. main reason I wanted the circuit.
If someone wanted to buy it as it is I would contact him and see if he would sell it.
Has anyone any ideas what it would be worth in this state.
Regards Jim.

Hmm, I might have one of these - have to check tomorrow. From what I remember, it works but the cabinet isn't in the greatest shape.

Please upload your picture.

Robbert.
The case would clean up pretty well I did not see any cracks it is brown Bakelite. My email is available. If you want to send me your email I will send you a set of pictures I have taken. I would rather not trouble Brad to upload more pictures he has done quite a few for me recently.
Regards Jim.

Jim, and all, uploading photos isn't a problem. Smile Well, it will be tonight as I am hitting the hay in a few minutes but I have a few things to upload tomorrow and will take the laptop to work to get it done.

100 specifies ECH 35 not 33 ECH33 differs by specifying the same conversion conductance at -23.5V G1 (heptode) as opposed to ECH 35 at -17V ECH 33 is specified to have a voltage divider on the screen.

Non tuneable IF 100A has dial marked CS 412 007 Set is Reflexed & not running a lot of volts .

Thanks Marc.
I am in limbo with this at the moment it looks like someone may want to buy it as is.
It is not mine so I will wait another day or two and see what transpires
Regards Jim

There is here a procedure called "assessment" and that is irrespective of it being a commercial repair or not.

One aspect looks at it in a physical sense like general condition, influenced by what the customer wants. e.g. I don't normally do radio cabinets. But I have with the customers blessing, sent one wooden HMV cabinet to a professional for finishing after I have sorted its other problems. Big wow factor for the customer & that's the most important.

Then there is the chassis in the case of a radio. There is the safety angle as to what is required to make it safe to run. And the costs involved in getting it to that point & working. That basically governs the viability of a repair.

There is as an example, a neighbours tractor that has been sitting out side for years. At a glance, No battery, fuel tank total loss,, no distributor cap & wiring, radiator not worth repairing. carburettor missing, anything rubber finished, 1/2" of tar on top of the cylinder head inside. no exhaust chimney, cylinder 3 locked solid from water, water in sump bonnet damaged etc... So basically the whole unit needs pulling to bits and putting back together. Not counting labour that would be close to $3K just for the engine, and there was 5Litres of water in the transmission. I could buy him a working one of the same, for a fraction of the cost.

Helo,Marc.
I have been doing these radios for him mainly to stop me going mad with boredom. Having said that he has always given more than I have spent on them and more than I asked for. He is a decent bloke so it is working both ways.
This one is a bit different because of the issue with the mains transformer . Finding one with such a low secondary , I think 185V a side might prove a problem most I have would be about 350-380 v a side which would mean a large dropping resistor wasting power and building up heat. With all this virus situation I have not been doing my 3 mornings a week voluntry work. Having said that I am now doing one morning a week back again for our local Dapto Anglican Opshop. I do saftey checks on there electrical appliances so they can sell them. It is good to be back doing something useful for the community again.
Regards Jim

The cabinet will wash after you get rid of, or avoid anything that can be damaged by water. Can't really assess the blurry pic Tripod is not dead, Or sit it on the garbage bin sideways in sunlight: Do that often. Autofocus is not you friend. Use the highest number f stop you can and manually focus into the centre, do not get too close getting back & cropping later can really help depth of field.

I did make a comment on the black caps: As I thought, bin material, testing them is a waste of time. Do not pull the metallised valves out by the envelope, lever them out & check the bond between base & envelope.

There are a few transformers scattered around the place here. in scrap radios. The Nipper ones are only 250V Heater current is a factor. Losing a few volts in not an issue if you get rid of, or lower the first cap size for starters, choke input filter will help.
