I have another radio that I need to get an id for. Hoping to find a schematic.

Will be making a cabinet for this one hopefully.

It had a rectangular dial and has a magic eye tube.

Four controls, On-Off/Tone, Volume, Tuning and selector for 31m,25m,15m, B.C and P.U.

Valve are: 5V4G, 6AN7, 6N8, 6SL7, 6V6GT, 6V6GT and 6U5 Magic Eye.

The blue arts sticker has the number 662073 on it.

There are no other identifying marks other than IRONCORE on the power transformer and two hash marks, one on the underside of the chassis and one on the tag board under the power transformer.

It came with one 5 or 6 inch Rola speaker connected to one 12 inch Rola speaker with a transformer mounted on it.

I have also acquired some loose parts which I believe came from a parted out Kriesler unit of some type.

All I have are the Power and output transformers and the valves.

The output transformers have kriesler on them. the valves are:12AX7, 6V4, 6N8, 6AN7A, 6M5 and 6M5.

Any information on either unit would be greatly appreciated.

Cheers


Gary

"Classic" model CB of 1952 matches the first line-up, minus the 6U5.

The second line-up looks odd for Kriesler with a 12AX7 and 2 CM5s.

A fairly typical line-up for Kriesler was: 6V4, 6AN7, 6N8, BD7, 6M5

British General Electric (BGE) model BC72 of 1955 had: 6V4, 6AN7, 6N8, 6AV6, 12AX7, 6M5, 6M5

Some with the given line-up include:

Electrosound model J611 HI-FI 3 (1954)
Electrosound model D63 modified (1955)
HMV model A1-42 (1954)
Kelvinator model AIK4B (1955)

Thanks GTC,

Looks like the transformers and valves are not a set.

Would other manufacturers use Kriesler output transformers?

No idea how I missed it but the two Kriesler output transformers have one of their wires labelled 6M5 with a tiny piece of tape so it seems they have been together at some stage.

Power transformer is a lay down type dated 1968.

1968 puts this in the Kriesler stereogram era, which would explain the 12AX7 and 2 x 6M5. However, they tended to use silicon rectifiers rather than 6X4.

I'll look a bit further.

A valve a day keeps the transistor away...
