These Precision machined 6061 aluminum Plate Caps remove an incredible amount of heat from the plate pin of the Eimac 3-500Z tube as compared with the original style Plate Cap (Anode Cap for our friends in the UK). This gives the operator a comfortable margin of safety regarding the Plate Pin Seal Temperature when operating his amplifier at elevated continuous duty output.
Disclaimer: These plate caps are not intended to increase the original ratings of the tube or amplifier, always use good engineering practices and follow the recommendations of the tube and amplifier manufacture when in use.
