Yes It worked! I bought electrical contact cleaner and removed the head. Cleaned all the pots and 1/4" jacks, push buttons, and pin connectors. Even sprayed some on the foot switch (the chorus switch hasn't worked for a long time) Everything works like new! I even armor-alled the cabinet and it almost looks brand new. I have owned/played this amp for 17 years and am happy to have it all working again. Thanks for the advise. Aaron
