I am so glad that I found this site. I'm a user of Macro Reference. I come from China, I have used this amp many years and this one is my favourite. Unfortunately, it can't work again now. When I turn the switch on, there are spark at relay K1 resistor R1. I would like to know what problem of that and use what kind of resistor replace it, maybe it is a PTC resistor (J0558-7 R1).Thanks!
