Hi I have a AWA fisk chassis the chassis has a number P251/ it has 8 valves plus a tuning indicator. The valves are 6A8G, 6K7G, 6K7G, 6H6, 6F5, 6F6, 6F6, 80 plus 6E5 tuning. It seams to be a TRF set dual wave. On the cover covering the tuning capacitor is The Fisk AWA Radiola most cover are blue chassis is a grey to blue colour the unit is in excellent condition. I have looked in the Australian Official Radio Service Manual 1935-1955 and can not find it can any body assist with information and schematic and maybe a photo of the cabinet it would have fitted into. I did get a post that was helpful however I placed this question where all can see.

I did post this in the wrong area (Under Forum) so I placed it in the correct spot.

Its 1939 listed R.R.A. 6/3/36 page 10 cost new in pounds 44/2/0

It was not unusual for a chassis to be under another number as well, & this one has two.

A set not ideal for the inexperience restorer. After checking I do have a circuit of it, plus (bonus) voltages.

It has one 6K7 as an RF pre-amp, that is TRF but with the Pentagrid 6A8. It is absolutely a Superhet with Delayed AGC and was made to take metal valves so there should not be any glass ones in the RF section.

That would be a Radiola 251. The label on the chassis would be R251.

Here is its page on Radiomuseum:
