Alright, so here's my story/predicament. I bought an Engl Invader 150 off craigslist for $1400 at the beginning of the year. I had it for about 4 months, thing sounded beast, worked great as far as I knew. Then one day I was shredding a lick and POP! That was the end of that. The only faint flicker of life comes from a dimly lit power switch. No tubes, lights, nothin'. So instead of bothering to open it up and do some self inspection (being at the time I had little self-confidence in my technical abilities) I brought it to my local shop I've been going to for a decade, who have done good by me thus far. Long story short, after being dicked around for over 3 months with every excuse in the book, the "diagnosis" was a busted power transformer, with a repair cost of almost $600. I declined the repair, and finally have it back here. Now I'm not the most tech-savy person, but until I can confirm this myself, I'm not gonna roll over and let this amp die on me. After being shafted by the shop I really can't take their word for it because.....who wouldn't wanna make $600 heh. I'm gonna crack this baby open on my day off tomorrow and do some investigating with my father, and see what the deal is. What do you guys think of this? Does it sound like a dead power transformer? Could it be something much less serious tripping up the whole amp? What should I be looking for specifically when I open it up that would be a tell-tale indicator? The lesson I am taking out of all of this is to learn to be more self reliant when it comes to self-educating myself about the gear and technology I buy. I've been doing some research the past few months, but not having the amp here at the time didn't help. Thanks in advance for taking the time to actually read through this and any help/advice you can offer would be much appreciated.
