Default Sage Amplifier!

Hello!
I would like to get some information about Sage Amplifiers.
I have both 70W 8ohms and the 250W 8ohms amps but one of my 250W module started to send out -75VDC and burned my woofers...
Anyway, I really like the sound of theese amps and I would like to know if there is any possibility to buy such modules still?

I would also like to get info on them if someone have, or a scheme so I can rebuild the broken one.

Jonas

Default recommendation for speaker protection

Any suggestion for a speaker protection circuit? I've tried the one that comes with M250 for my AV400

http://www.astro.uu.se/~marcus/private/m250.html

but it seems to be unsuccessful.

JensRasmussen and I are in the middle of the construction of complete amplifier and speaker protection circuit, which includes soft start, DC- and thermal protection etc.

hi

I got a 2 of those 250W Sage moduls and am planning on using them. What was the unloaded transformer voltage you used (woul be good to know so I can degrade to prevent burning those modules)

tnx in advance
