Need help w/Mark IV amp. What am I doing wrong?
Okay, I just bought a Mesa Mark IV from a fellow jemsiter (thanks Chris!). I basically have the 1X12 short combo but he also included the original head cabinet. I played thru the combo yesterday and it sounded AMAZING! Today, I transferred the guts into the head cabinet, hooked up the reverb & fan, and hooked it up to my Mesa 2X12 recto cab. I turn it on...wait about 2 minutes, switch standby to ON and...nothing. Just a mild hum. I can tell the fan is not running. I then tried to hook up the original combo speaker as well, still nothing. Since this is my first tube amp, I want to check with some experts to see if they can help me troubleshoot the situation. Thanks!
