Description

The ML-102A is a high-vacuum rectifier tube having max- tion which characterize Machlett high-vacuum rectifiers for imum ratings of 75 PKV inverse voltage and 750 MA peak high-power-level applications. These features insure rugged- anode current. It is especially adaptable to electrostatic par- ness, long life, low internal voltage drop and high average ticle precipitation service of moderately high power require- load current capacity. The cathode is a pure tungsten fila- ments, where its low initial cost, long life and high current ment of the catenary type, allowing close anode-to-cathode capacity make it highly practical and economical to employ spacing without distortion of the filament by electrostatic
