Test set T-105
Test set T-105; manufactured by Autophon AG, Solothurn.
Autophon developed a test set matching the SE-206, SE-207 and SE-407 radios for alignment and repair work.

Operation
The mains or battery-operated T-105 test set developed by Autophon allows maintenance and adjustments on the Autophon SE-206 / SE-207 and SE-407 radios thanks to the built-in RF oscillator, which covers the 34 - 50 MHz frequency range.
In addition to the radio frequency oscillator, which can be modulated at 1000 Hz. I1t also includes a crystal-controlled oscillatror working on the IF of 1.65 MHz and a tube voltmeter and ohmmeter for measuring the anode and heater voltages, among other things.
For operation, the tester is connected to the radio with the measuring cables; the radio can be controlled from the tester via the operating cable without a headset.
The measuring instrument can be used to measure DC voltages of 3 V, 30 V, 300 V, 600 V and AC voltages of 3 V and 30 V. Resistance measurements with three ranges are also possible. The 12-position measuring switch can be used to carry out the same fault isolation measurements in positions 1 - 8 as with the EJ83 test instrument; the test set is connected to the measurements socket on the radio or the SG94.
The functions and test procedure are described in the regulations.

Tube configuration
V1 (1V6, IF oscillator); V2 (1AD4, AF oscillator 1000 Hz); V3 (1V6, 2nd stage IF oscillator); V4 (1AD4, RF oscillator).
Development
The T-105 was developed for maintenance and alignment work on the SE-206/SE-207 and SE-407 radios from Autophon.
