All that I did with the one that appears in SC was disconnect it & solid wire into I think the side with a reversed Gland (Console).
If I track down a photo of that I will send it to Brad. It was about 2009.

In this case the IEC is definitely the better choice.
Clipsal do make a 10 amp flush-mount inlet socket however this is designed for small caravans or commercial PA equipment and is too big for most radio chassis.

Have a look at the Bulgin range of power receptacles at the Elements 14 web page. They have a number of round connectors, 3 pin and rated at 250V at 3A, you might be lucky and find one that fits your chassis hole.

Well guys I finally got to start on the inards of this beautiful old set. The positives of this set is that it is very well made and any work I can do on it wont be difficult at all. Even the dial only needs a good clean and is actually made of very good quality material. The negative side of it is that some one has donned a striped apron ( Butcher) and plied his trade to the tone switch and the volume switch. These both look to be repairable but I want your opinions as to what to do. I have sent some photos to Brad and you will see what I mean . Not all of the old Techs had pride in their work and obviously this was one of them. Maybe it was a bit of backyard Butchery.

Well I have managed to get those pots checked out and they are easily repaired. The issue is that the transformer is not original and is fouling the pot nearest it. We have worked out how to fix that issue. I don't know why the original tech couldn't . This has been converted from 2 volt to 6 volt valves but I will leave that as is

The origin of the black marks on the side next to the transformer lugs needs investigation. That may not be that transformers doing but it does suggest some form of corona discharge or bad wire? May pay to put / glue some additional insulation paper there.

A very nice old radio, I'd be really interested in seeing the results after it's cleaned up and had all those caps replaced.

My first job with this one is to repair the Pots. I can see that one of the coils has broken wires at one end and will have to rewind it or just take the unbroken end to the terminal. Can I join new wire to it and what sort of wire can I use. Other than that is there a service that rewinds these items .I also will be looking for a schematic to this baby. Another thing I really want to do is stuff the new caps into the older ones as the shells of the old ones are in such good order. As for the transformer it is not original and I will have to neatly cut the edge of the biscuit board so as to clear the pot. I really am at a loss as to why this was left this way. And Marcc I think the corona you are pointing out may be from the old transformer as there is no way that the new one or the wires around it can hit the chassis. One other question I have is what do any of you use to clean the chassis as it really is filthy on top but it will be ok.

The wire in the pot may not solder as it is probably Nichrome resistance wire. The only one I know that repairs them is Mark Oppat in USA.
Normally I just replace them. You should be able to get an idea of its value from what is left, by adding either side of the break.
Some of those caps may be coated in a hard rubber type jacket & that will shatter. I don't think I have any old Channex of that type lying around, but I do get them.
Watch the long green (candohm) resistor they suffer corrosion & are notorious for going open (wire breaks). The last EMMCO I copped had no circuit. As I probably noted (Its in Silicon Chip as an unknown set). I reverse engineered that one & it had been hacked (there is now circuit for it). Beware of the top trimmer cans, one of those screws is liable to be on a primary & alive: A metal screwdriver can short it.
Chassis depends on what the grot is? Start with a brush & vacuum cleaner. It looks a bit like rust, but get the loose stuff of first, then we re-appraise.

Well guys I just had a brilliant idea. I am going to ask one of my younger friends to 3d print the old capacitors for me in the form of open ended tubes and photo shop the markings for me on some stickers so I can easily disguise the new caps as the older ones . I may even ask him to print up a lot more than I need so if you guys need any then I will have them for you.

Well Marcc I have worked out that you were correct in saying this is a troubadour instead of a Jewel I stand corrected. I have managed to find it in Radio Museum listed as a model 454 with all the valves I have listed except for the 6F6G ( 42 instead ). Now armed with this info I will be looking for a schematic.
