I bought an old radio the last time I was in Queensland as it looked like a decently large mains table radio.

However when I got around to look at it, it was a battery set, but using the same case and chassis as the mains version.

The valves (from what I recall) were 3x 25L6GT, and at least 2x 6BH5, maybe a 6AN7 and a 6AD8 (not sure about those).

Is that enough info to identify it?

Thanks.

Bit of a lottery. Would be an idea to get some photo's of it & chassis & a confirmation on the bottle labels. Pentagrids like 6AN7 are from early fifties.

Yep, that is more than enough.

Sounds like a Astor QP, a 32 volt home lighting plant farm radio. Whoa

Thanks. I noticed the heaters were joined to the HT, so I guessed the entire radio ran on a lower than normal voltage. That would explain the extra IF stage(s).

Thanks Monochrome TV for helping out Smile

A valve a day keeps the transistor away...

Being 32V it was designed for the bush & 32V lighting systems. It was likely designed to pull in & separate stations a long way from it.

Dug out the chassis, it has a fuse holder on the back. The valves are in slightly different posistions to what's described in the manual. No record player (although it has an input socket).

Valves (left to right): 6BH5, 6AN7, 6BH5, 6BH5, 6AD8, 25L6GT. Then there are 2 more 25L6GT behind the first one.

Looked for a model number, no luck. The number 37 is stamped on the chassis in 2 places. A serial number started with 0N.

Astor ANR and QN models share that lineup with the QP.
