Another Ebay find of one of the 7000-series test-and-measurement devices from ELV from the 1980s.
It can measure the current-gain of NPNs and PNPs at 5 different base currents with collector currents up to 2 amps.
And additionally the breakdown voltage and leakage current at voltages up to 200 volts.
