The modulator tubes are a pair of 6L6GAs

Octal Connector Pinout:

2.  6.3V (speech amp and modulator tubes only)
3.  Control (antenna relay and dynamotor)
4.  B+
5.  N/C
6.  Control (antenna relay and dynamotor)
7.  6.3V
8.  6.3V

NOTES:
Pins 2 and 3 jumpered for phone operation or broken with a switch for mobile
                   operation to reduce battery drain.

Pin 6  Ground for PTT

Pins 7 and 8 jumpered

73,

John,  W4AWM
