Hi, I'm new to the board and to Kustom amps. I recently purchased a K200B-3 serial# 27081 with matching 2x15 cab. I purchased the head understanding it had some issues, mainly channel 2 was not functioning, the pilot bulb and lens was missing, and channel 1 had filthy pots and had some static. I opened up the amp when I got home and it was extremely dirty so I cleaned the pots and attempted to clean the dust out. It seemed to sound somewhat cleaner but still nothing from the second channel. In trying to work the second channel I noticed that working the selective boost knobs produces extremely loud pops. I left it at that yesterday and didn't mess with it anymore. Today I was playing through the first channel for maybe five minutes and the sound cut out and I was left with a loud, steady hum, almost like a shorted speaker. I ran another head through the cab and it sounded fine albeit a bit buzzy. I opened up the k200 and reconnected the cab and noticed a spark. My questions:
1) What could cause the sudden failure of the first channel?
2) Channel 2 seems like a bad input jack but what would cause the popping on the boost?
3) Does the missing lamp cause any issues other than appearance?
4) could the buzz in the cab be from a dirty jack? its noticeable across the full range and the speakers otherwise sound loud and full.
5) Am i correct that this cab would be 8ohm? the only markings are kustom by ross on the front and altec on the back plate.

Sorry for the long post and thank you for any help
