Hi allSkip Simmons might be able to help you out. He's big into the Mascos. http://www.skipsimmonsamps.com/
Does anyone know of a "Masco graveyard" site kinda like a junkyard but harmonica amp parts? I'm looking for the socket and "wired pin" that makes it easy to change to different ohms as needed.
TIA
Hal
Good luck! Brad
