Another thread has reminded me of the Crest Audio 10001. Has anyone owned or worked on one? 9001 was as high as I got... I remember a comment where someone said there's enough charge to vaporise a screwdriver!
  Were there any other amps of that period which could offer the extremely impressive overall specs of this beast?

The Crest 10,001 was marketed as a 1 ohm amplifier. It never fared well against the QSC Powerlight 9.0, Crown 5000vz in addition to the Crest 9001. At 4 ohms per channel I believe it was around 1600 watts per channel whereas, you had the QSC Powerlight 9.0 offering around 3200 watts per channel @ 4ohms.

As far as i recall it has 160.000uf/ch....so yeah...enaugh capacity to melt down a screwdriver no problem LOL i had one on my hand a decade ago....bloody heavy things Confused,btw a 9.000uf/100v Philips capacitor charged to 60v only had evaporated my Fluke probe tip LOL

So...just imagine what 160.000uf/100-150vcc high ripple capacitors as in that Crest fully charged will do when shorted LOL

The Crest 10.001 is a high current dumping amplifier,it wont perform great in high impedance,you feel his guts when you push it in low impedance,or bridge mode low impedance as well Smile

It has 2 front panel power switches/circuit breakers, similar to the 10004. Whereas the 10004 was simply 2 8001s in the same chassis, I think the 10001 was a pair of 9001s but each was stacked and wired to act as half of the swing. It's interesting in that with such a low impendence drive it could power multiple speakers simply in parallel. 4ohm stereo was not for this one!

Useing Crest Audio Pro 10.001 on 4R loads is just a waste of usefull power Smile on the other hand useing it bridge in 4r on 4 18inch loaded scoops....that's another story to tell...Big smile ofcourse you need 16r bass drivers :) if good quality drivers with high spl...and this crest...you will do earthquake :) also pay attention to cooling sistem as they have a habbit to get all the crap betwin those huge radiators and keep it all there,untill you remove it manually Confused however is listed as 1r stereo amp and 2r bridge mode...i won't recommend to be used as such,2r stereo and 4r bridge for trouble free operation Smile also an elevator for transport LOL

As much as i like old and proper stuff...i never wanted to own one,i even choose two MT2400 and not 5000vz,the old crests and 5000vz amps are not the best choice when you need to carry them for here to there....Confused

When I stated 4 ohms per channel it was to show how low the voltage rails were. Even at 2 ohms per channel it offered less output than a MA 5000vz at 2 ohms per channel. Participated in a test over 20 years ago comparing the Crest 10,001 vs the Crown MA 5000vz and, QSC PL 9.0

It may have been a fine amplifier a 1 ohm per channel but, they were very disappointing compared to the Crown & QSC @ 2 ohms per channel. Even the die hard 2 ohm per channel users rather use two MA 5000vz at 2 ohms per channel (16 boxes total) than one Crest 10,001 at 1 ohm per channel (16 boxes total). 

That amplifier had a lot of hype until people start buying them. The Crest 9001 has larger rails than the Crest 10,001. The biggest Made in the USA amplifier at that time was the QSC PL 9.0

If I'm not mistaken, 10k amps (Crown Macrotech 10,000) were built for MRI machines. Probably Crest 10001 as well. LOL

Yes, I would definitely prefer, say 2 x 8001's than use a 10001.

One guy I knew here years ago ran a huge ASS system with Harrison amps. His pride was a 10,000W jobbie, that one day blew up mid-gig and left him without any bass. No joke.

He also had some of the 5000W ones that also died on him. I don't think that they were the most reliable of amps...   Dead

I once lost a all mid tops on my ASS rig with 2 hateful Harrison's going down. I always looked at the spec sheets of those 10k in awe.
