- Inlaid rectangular brass+ wood case with "antiqued brass" face plate. Drum type tuning indicator, 3 control knobs (Tuning, Volume, Clairifier). Also for 25 cyle ac. 2 chassis located across the back of the enclosure, 1 pwr supply and the other an audio section. There are 2 grid leak resistors on the audio chassis, a 10 meg located in front of Main Board tube #1, and the second is a 2 meg located between tubes 2 and 3 on the same board.
There are two transformer cans mounted in front of the power supply chassis, one marked " 25 CYC STD", the other unmarked as far as I can see.
In front of the main chassis is the tuning drum (indicator) which is illuminated from above, and covers 540 to 1450 Khz. It is marked both with freq and a log scale.
Beside the drum there is what appears to be a variable pot. Value unknown at this point in time. It is attached to a knob on the front panel and is marked "clairifier". Beside the clairfier, and again in front of the main chassis are 4 ganged tuning capacitors.

Ich besitze seit ein paar Tagen ein Radio vom Typ 38V.
Leider kann ich nicht ganz nachvollziehen wer der
Hersteller ist ?
Das Typenschild (siehe in der Anlage) trägt den Namen
"His Maste s Voice,Limited." und stammt wahrscheinlich
aus Kanada ?
Wer kann weiterhelfen ?
