CK-516 Electrolytic Capacitor Replacement Kit for the Collins 516F-2 Power Supply The CK-516 is a complete kit of electrolytic capacitors needed to re-cap the the Collins 516F-2 power supply. Unlike other kits, this kit INCLUDES a newly manufactured dual-section electrolytic capacitor. The following replacements are included in the kit:
3 - 33 uF 450 VDC for C2, C3 & C4 2 - 10 uF 450 VDC for C6 & C7 1 - 0.05 uF 1600 VDC for C1 1 - 15/30 uF 450 VDC for C5A/C5B Our Price $50.00 - Shipped in the USA - International shipping cost to be added. | 
The PM-300 is a complete replacement power supply module for the Collins 30L-1. It features new modern 180uF 450VDC electrolytic capcitors, 1000 PIV 3A diodes, new 100K 3W bleeder resistors, upgraded meter shunt resistors and a precision high voltage meter divider string. 
The SS-516 is a complete kit of parts and instructions to convert the Collins 516F-2 power supply to solid state operation. The main advantage of this conversion is removal of excess heat from the supply and prevention of tube arc over. Included in the kit are solid state tube replacements for the 5R4 & 5U4 tubes, a replacement for the selenium rectifier, meter protection diodes for the radio, a transient suppressor, a dropping resistor and complete step-by-step installation instructions.
