Ive looked for the scematics and alas they are nowhere to be found The MOSFETs are already history I beleive and so Iam really open to suggestion on the next set of actions to take.

HEXADYM magnet system Hi Everyone, Great to be part of this forum at last I have a request to anyone that can shed some light on the current issue with my Crescendo amp.. I think that goes to say something Any how I have spent some time on the amp and have seen the following.. The T29CF002, ”CRESCENDO” is an Ultra High End 29mm soft dome tweeter with a.. Your FET(s) may have blown as a result, or for other reasons including output shorts, electrostatic damage to the gate oxide, etc.. amazingly my tweeters survived!!! Now I am looking at Lateral Mosfet of the type pip has suggested!! Thanks pip I shall check these guys out and try to procure the devices.

You may want to take a look at the TDA7294 or the LM3886 Thanks for your inputs linuxguru.. It was manufactured from 1979 to unknown Lori Midgett (March 12, 2009): Hi maybe you can use what I have.. The result was a blown MOSFET and the worst part is it took my 12' woofer( Klipshhorn) with it.. DC drift was one of the reasons as the zener diode D1 was showing around 4 7 volts and the damping cap across it C8 looks completely open( tested with a DMM). Download Triple A Maps Mac

I am currently looking to see what mods,if any,will allow me to ressurect the Crescendo's again.. Just for your info the Crescendo once stabilized worked like a charm for around 19 years without any instability problems whatsoever.. HELPjavascript:smilie(' ') The Crescendo was prone to a lot of instability even when it worked - it was prone to oscillate under a lot of conditions, including reactive loads.. The original (Hitachi?) FETs are probably going to be hard to find, so you may have to modify it to use commodity FETs like the IRF540/9640 instead.

The amp was constructed by me way back in 1989!! Has been working till last month!! Now I get a heavily distorted sound with a lot of DC on the output --around 20 Volts without the LS connected of course.. I know this is really insufficient info to suggest anything but is there anybody out there who might have some suggestions to go about fixing this.. Currrently my thinking is to gut the internals and make a brand new MOSFET if I get the time!!!!Advertisement General information The Audire Crescendo is a power amplifier in the solid state amplifier category.. I have already blown one channel of my Klipsh horns and do not dare connect these back till i fix the problem.. Search the forums for info on how to go about this Just BTW, just about any entry-level gainclone/chipamp today works more reliably, has better specs, sounds better than a Crescendo, and costs a small fraction of the Crescendo.. I own an Audire Legato and Crescendo which I purchased two years ago Both are in pristine condition and I am happy to have them. 773a7aa168
