Rolls Radio Transistogram

[Mike Watterson]

It probably also has a DL96.

There were some 4 valve battery radios in UK that also had wind-up gramophone variants. Alba made one.
This is the earlier 50mA type battery valves Alba 707. There were single, multispeed and export versions

DK92 DF91 DAF91 DL92

Later models of the same idea would have been using:
DK96 DF96 DAF96 DL94 or DL96

The DL94 takes the same filament current as the DL92, but has much more audio power than the DL96

The DK96 is almost always only in radios (Mixer & Osc).

It's possible there is also a transistor model in the same case.

Transistor sets existed several years before the 1957 Vagabond, but cost more than valves.
