my webb needs help

okay guys, here is my predicament, my webb toasted 4 output transistors? (i hope i got that right), and now the tech can't get them out because everything is frozen in the amp, he says the solder is put in there like webb never thought the amp would need repair, and all the screws are completely frozen. he has let the screws sit in wd-40 (or something like it) for like a week, only managed to get one out. he has never seen soldering so intense before and is ready to give my amp back without fixing it. what am i to do about this? do you guys have any experience with this kind of thing (i don't), and is it possible to find another way around this by creating a new piece of the board or something like that? i am not an electronics guy, but i thought i would put this up there and see what comes, thanks in advance for any info you can provide me, peace.

Go to a different tech. That whole story sounds fishy. Never heard of such a thing. Those output transistors may have solder around the
mounting screws, but you don't soak 'em in WD40! You have to use a solder sucker or solder wic to draw the solder away from the screws so you can loosen them. You can also just turn the screws while heating the solder to break them loose.

It's also possible that only one output transistor is shorted, but because of how they are hooked up it will appear that they're all bad. If you find and remove the bad one, your
meter won't read a short any more. It's also
possible that the short might be in the power supply and not in the output transistors. I'm
assuming the main fuse keeps blowing, right?

Try another tech. I do believe those screws are soldered in. They're not frozen or seized up.

thanks for the info. i'm thinking he knows what he is doing, but for some reason, everything he tries isn't working. the screws are frozen to the point to where they won't turn, and the solder is i'm guessing from his description "super soldered". now, i know from my own small time soldering that solder just needs heat to get it to free itself, so i'm not understanding that aspect, and if it is true that the screws are soldered, then it would stand to figure that if he isn't aware of this for whatever reason, wd-40 isn't going to get the job done. i'll send him an email telling him of this stuff and see what happens, thanks
