Hi Jeff, Glad to see you are still around. The two S's were my first port of call....you know how hard it is to knock new information into my head. Apparently there is no visual indication. They've suggested cleaning the unit with ISO etc but I think

Hi everyone, I've been out of it for a while after 27 years. Got made redundant in February. What can you do? I know - turn 60 and get cranky. That'll be the ticket. Anyway...... Trying to help someone out with a Yamaha YVL88MKII. I am very conversa
