Hi guys
I just bought a mark ii c+ and love it. It was shipped to me ground, and took a week to arrive, so I assume I was riding on a truck for a week. It worked well for about 2 days. Then the crackles started. At first it would crackle at startup for about 10 minutes, then after about 3 hours. Then it would only crackle at startup and after an hour. Eventually it crackled every time it was powered on. I bought new tubes and installed them. No differemce. I should also mention I swapped the speaker.
So I took it to my usual repair guy, and here's what he did - 1. Gave it a good once over, including fixing a loose/falling apart solder joint in the V1 socket. 2. Swapped V1. It didn't crackle at his shop. Of course I got it home, crackled immediately the next morning. Called him back then took it back. He then 1. Swapped both power tube sockets. 2. Re-tensioned the preamp tube sockets. 3. Gave all the tube sockets a good cleaning. 4. Replaced one cap. Not sure which one.
He had it on at his shop for two hours with volume at max through his own speaker cab - not a single crackle. I thought it was fixed - after an hour of use began to crackle.... took it to a local big repair shop. The guy there didn't seem like he knew what it was either....
So I'm looking for either a diagnosis I could call this guy with to help him, or a good boogie repair shop in Chicagoland. Help!!!!
