Have an old silver sabre 2 i purchased new back in the mid 90's. love this thing and it still works fine except the on/off/sensitivity pot is starting to fail(imagine that after nearly 30 years!) and i can't seem to match it up anywhere. Its a 10k 5 pin alpha brand pot that tesoro probably used on numerous models over the years that apparently was made as proprietary just for them. Would anyone by slim chance still know what the factory part number is/was for this stupid thing? If i can't find it or match it up somehow then this old gal will soon end up on the scrap pile, and thats a shame just due to a cheap little dial
