Bad solder

[Breyn77]

I have the s1-45, recently i cant get any sound for a few minutes after turning on then a pop and its works fine, I've read online probably a bad solder joint. Anyone have this problem or solution?

I had a similar problem on my S1-45. Before you get the soldering iron out, try this:
SWITCH OFF AT THE MAINS AND REMOVE THE MAINS CABLE. DO NOT TOUCH ANY COMPONENTS AS THE AMP CAN STILL STORE CHARGE. Take the cab apart and take the amp chassis out of the case. This is a bit of a pain. Look at the PCB, you'll see lots of little connectors there. I found that several were loose. One by one, CAREFULLY remove and re-seat them all. It fixed it for me and I've had no further issues in two years.
Good luck.
