PM-MKII Replacement Power Supply Module for Swan Mark II


SKU: PMMKII Category:


The PM-MKII is a complete replacement power supply (rectifier PCB and filter capacitor PCB) for the Swan Electronics Mark II linear amplifier. It features redesigned rectifier and filter capacitor PC boards, new modern 330μF 450VDC electrolytic capacitors, 1000 PIV 3A diodes, new 100KΩ 3W bleeder resistors, upgraded surge resistor and a new glitch protection resistor string.  The original CW/SSB relay mounts to the new filter capacitor board using the original hardware. Due to the length of the instruction manual for this kit (9 pages), and the number of pictures in the manual, printed instructions are not sent with the kit.  You may download a PDF version from the DOWNLOADS section of the website complete with detailed step-by-step assembly/installation instructions and color pictures.
