Wireless Set 19 - ID - Help Please

[Rod Salter]

Hi All,
Recently I swapped some radio chassis for a 19 set,

Of course the Identity Plate is missing! (Scrap brass must have been worth a fortune, once)

The layout is different to my other sets

The only valves in it when I picked it up, were the big 807 and the little 6H6GT glass valve,
Unusual that they were left in it.
Also strange that the 6H6 is not a little metal unit.
The 807 is near the tuning condenser.
The wire to L3a has come adrift.

I have purchased all the other Valves from Joe Oost. (Thanks Joe)
They all light up, the filament circuit must be intact, this is a good start.
I have repaired the Square meter and it now works. (On 12 Volts range)

There are 3 output valves - big 6V6Gs
b and ic.jpg
The B set tuning condenser and the valve 9072 (What ever that is ?) have been removed.
The valve arrangement in the B set and the IC are different to the other sets.

Underneath are tag strips everywhere, What a nightmare to wire in?
And a bigger nightmare to trace to the valve sockets, almost impossible I should think.
The plus side is the caps should be easy to change.
Maybe, As there is thick varnish sticking everything together!

Quite obviously AWA Australian made by the look of the condensers and the rounded transformers.
The trimmer condensers have been pirated as well as the 6 pin power socket, shame actually, as the set otherwise appears unmolested.
Except there seems a-lot of space there on that side of the chasis.

The only number I can find - 12475

On the bracket that holds coil L3a, in fact the only number in the set.

So 'What is it' ? Please

What is a 9072 valve ?

Advice or pictures of the trimmer capacitors in place would be appreciated,

I would like obtain/purchase a circuit for this particular model.
All 9 of the valve shields are missing too, these I would like to obtain/purchase as well.

Any other 19 bits (obtain/purchase) to complete this set would also be appreciated,

Thanks, cheers rod
