Brenda Ann:

Anyone know what it's FOR?

Says Pacent Adapter, and was between one the 71's and the socket in a Bosch
28 I got in today.



Unless I'm confused, it connects to pin 3 (grid) and 4 (filament) of the
'71.

My guess is that it's to feed audio from a phonograph or shortwave radio
to the stage without having to modify the radio. I'm not sure what it
would do in a push-pull stage such as on the Bosch 28, nor why the
adapter doesn't go to the '26 audio stage instead.
