Hello Kent,
Thank you very much for the part numbers, unfortunately I was not able to come up with anything even with a search through
www.partsvoice.com. As for the other option for resistor (25J75RE - Through Hole Resistor, 75 ohm, 20 Series) I would certainly consider it regardless of originality if it did the job... Thank you for the lead.
Lastly, something else found through a Plymouth forum is a gentleman (James Peterson) that produces an electronic voltage regulator. Best part is that it does not alter the appearance of original unit...
