WHAT CAN THE MULLARD HIGH SPEED VALVE TESTER DO

Today, I have had an e-mail from Veaceslav in Moldova, asking what tests the MHSVT can do.   This valve tester can do seven main tests sequentially and these are: - 

Test 1: check heater filament continuity.

Test 2: check insulation between electrodes - cold.

Test 3: check heater - cathode insulation.

Test 4: check insulation between electrodes - hot.

Test 5: check reverse grid current is acceptable.

Test 6: measures emission indicating 'goodness' on a CRT screen.

Test 7: checks correct connection of each electrode to each valve pin.

Parameters for each test are set using the test card for a particular valve which is slotted into the rear of the tester.

A useful tester but for me, I prefer the AVO VCM series and this is what we use at Mullard Magic HQ.
