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.

Technical data

  • Principle: Voltmeter, ohmmeter, 100 μA; device-specific measurements; RF oscillator 34 - 50 MHz, IF oscillator for the intermediate frequency of 1.65 MHz, AF oscillator 1000 Hz

Power supply

Dimensions

  • 353 x 227 x 210 mm, 7.5 kg

Accessories

  • Cable set in lid section, regulations

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.

Technical principle

Quartz-controlled IF oscillator 1.65 MHz (two 1V6), AF oscillator 1000 Hz, RF oscillator (1AD4).

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.
