MM 410HD 150 back after 25 years

Hi Guys, proud to say my uncles amp that we loved when we were young is back!! I received it when he passed away unexpectedly and we were very close. The family wanted all his new stuff like a fender blues jr and a marshall 40 watt anda masrshall solid state double stack and an old bassman but not me. I found the music man in the garage piled up with junk mouse nest on the reverb tank cob webs you name it. I knew how much he loved that amp. When the pots got bad he put it in the back room and there it sat. I posted another topic under model and serial numbers. You folks said it has EV Force speakers. My uncle was told by the music store it was a prototype, I now don't think that is true. It took a lot of cleaner and the corner protectors were rusty. I took them off and cleaned them up removed the chassis and cleaned the pots put new tubes in then put it together. I found reading this site it has to be biased but I wanted to turn it on for a second. BAD MOVE the fuse blew so I pulled the Tubes out. I'm an honest guy so I got to tell you what an idiot I am. Ive switched out tubes for years and this time the alignment pin was off and I knew I screwed myself. I couldent sleep at night very well so I went to the local music store and they dident know Music Man ever made amps so that was scary. I was reading this site and came across a man on here named Terry Loose that fixed Music Man amps and posted a repair in 2002. I emailed him and he replied. I told him the stupid thing I did and he had me send him my amp chassis. Turns out the Driver Transistor was bad and the Driver Chip was bad as well. He said it has the DB-4 board in it and he liked that version. He also recapped it for me and sent it back. I was so paranoid putting the tubes in!! All in all Terry saved me Thank you guys and Terry thank You!! I just want to do something that would make my uncle proud and this was it. That amp Rocks!! Played on it 2 hours last night. I noticed its different then most amps. You can dial it in to have slight break up or super clean or distorted. I love the power and the reverb. Music Man is truly one of a kind and now that I own one I'm a fan too!!
