I'm wondering if the transformer and choke were originally fitted to a speaker, but then transferred inside the radio...

I'm not in a position to see it again so I'm only speculating.

You either look at the info you can yet on it, or the physical layout. Often on the good data sheets (many of ours do not qualify).

The 10Kg+ Speaker of a "Lyric" 70 (All American Mohawk) series has chokes and transformers on an original 1929 "Rice - Kellogg" field coil speaker.

Chokes can be on speakers as field coils, or in and outside the pan and more than one (HMV R54) is never unusual.

Astor / PYE had a habit of running output valves 6V6 at maximum voltage pre-empted by a 6v6 screen resistor. That transformer was inside pan mounted on insulation, poorly protected, and was live frame.

Look before you leap.

I will take some clear photos this week and send them in. And thanks for the visit Robbert, I enjoyed the chat. The wife hasnt discovered the other radios yet lol.

Robbert , possibly the output transformer which Brad has suggested was under the phono in a metal box may have been moved to under the chassis along with the field coil because the tech may have had plans to make it into a smaller set!

Once an apparatus has been sent out into the wide, wide world; There is no telling as to what has been done to it.

Marcc I will have this set meticulously looked over. I am very lucky to have a competent valve tech friend that lives around the corner from me whom is always happy to help me .
The opinion I have of the other tech whom had this set is that he maybe a very good tech but knows little about doing things by the book. When I looked at his work bench I saw what looks like a dimbulb setup with a jug element in series with it which to me looked very dangerous .
Ie he knew what he was doing but no one else did so this raised alarm bells.
I see this a bit in my facebook groups ie a few very good techs that have little understanding as to why doing things by the book is the best way to stay safe.

The background of some doing all sorts of repairs can be quite interesting & formal training & qualifications with some also does not mean a lot. I was a shift supervisor in chemicals, the OH&S person in a sheet metal group and on a safety committee in chemicals and am involved in farming.

It is unbelievable at times as to what Heath Robinson constructions and lethal workstations can be arranged by the masses. You teach them OH&S etc. at work and it stays in their locker when they walk out the factory gate.

Often these days it is beware of the book. These are often written by academics (Covid being a prime example) that have had absolutely no practical work experience in the field and have no idea of the best way of doing things. Even to the point of dismantling items in the wrong order, or where there is no practical reason for doing so.

There is also the danger in writing work instructions for machines they have never seen or used.

We must also consider Einstein. "If a cluttered desk is a sign of a cluttered mind, of what, then, is an empty desk?"

Both the computer benches here and the radio (mainly) bench etc. are organised chaos. That works for me. Engineering is a different shed.

A case in point: Aussie Broadband add. The guy who tightens up the tap nut & tail by turning it the wrong way.

I suppose what I mean by saying by the book is using failsafes.
