Volfenhag ZX-7180 Amp Dissassembly NEED HELP

[Magnarider 10+ year member]

I just got a Volfenhag ZX-7180 from a friend and he said it worked but you had to keep wiggling the fuse to make it work. I dont know alot about Amp repair but when I took it apart I noticed that the fuse holder had broken its solder and was barely holding on to the circuit board. So I would like to remove the circuit board and resolder the fuse holder back onto the circuit board.

Problem is I cant get the circuit board out of the Amp enclosure. It looks like it slides out but I dont want to force for fear of breaking it.

Can anyone tell me how to remove the circuit board so that I can get to the underside of it to resolder it.

Thanks for any help.

Its not worth the solder to fix it.

I would do it for fun but I doubt I would even try to run it, post up some pics and maybe we can help you get it apart.

Pics would help though I would agree that it may not be worth the effort.

Did you remove the screws that hold the board to the casing?

I'd say it's worth messing with and will put out enough power for something. It's probably good for a hundred maybe 150 rms x2 @ 2ohm and maybe 4-450 bridged. Guesstimate of course.

Yes I took off the top cover and the side covers and that exposed the circuit board. The circuit board is slid between the aluminum housing. It seems like it just slides out of the groove in the aluminum housing but it also has things up on the side and im not sure how its attached and I dont want to force anything and break it so I wanna be sure about disassembly so that nothing else gets damaged. Im going to try and get some pics tomorrow if I get time. I cant find any screws in the circuit board itself.

OK heres the photos there are no screws in the board it self and it looks like it slide out but im not sure any ideas?

These pictures I have circled what im confused about if the board does slide out what I have cicrcled looks like some thing that is glued and and wont let it slide out. Maybe those can be reworked somehow any ideas. Thanks.

Those are spring clips that are holding the fets down. They are kind of wedged into a little notch right towards the top of the clips. If you are real careful you can remove them with a set of needle nose pliers or if you have a screwdriver you can afford to destroy you can make a little tool that will pop them off pretty easily for the most part. Be careful with them though man because if they are bent or broken at all they can be pretty hard to find replacements for sometimes. Putting these clamps back on is no picnic either but not too bad once you get the hang of it.
