Hi. Has anyone else come across this problem? I have 2x lab gruppen amps that self destructed. The flyback transformer unglued itself where the top bar of ferrite is supposed to be glued to the U shaped piece, this caused a voltage spike which blew some large capacitors and not sure what else yet.
Lab will not sell me a new transformer and they want £600+ to repair each amp.
I told them that this is a design fault and these amps are not worthy of being used as touring amps. No wonder Brick Row must carry 2 of everything when on the road!
Basically, i am hoping to be able to re glue the transformers back together and then to change the capacitors that blew. I'm then hoping they will come back to life as i have 3x of these costing me around £1000 each used price. With those destroying themselves along with my QSC Powerlight 6.0 and a large mistake with a DSP with non working screen blowing 6x 6.5" drivers and my old processor shitting it's pants, it's safe to say i have lost more money than i made over the last few years with this equipment. Depressing to say the least, especially with the current state of affairs, there are more details but i will not bore you all with the situation.
Hoping to find some help here with the rebuilds and wondering if anyone has come across the same situation. I find it had to believe there is no info on this issue online since i already have 2 of these with the same fault.
Also any recommendations on a better glue for shiny surfaces would be appreciated. My first thought is epoxy but i know that it can peel away from shiny surfaces, i also have chemical metal but it's probably too brittle. I'm also wondering if the glue needs to provide an insulation layer and if the gap where the glue sits between the U piece and the ferrite bar is critical?
Thanks.
James
