This Amplifier will work on a continous basis into 4 Ohm loads @ 800 watt RMS

"Go out and buy a DVD copy of "Attack of the Giant Leaches",
a Corman classic and an absolute must when plannng the
size of your amplifier."
Why did they pair "Attack of the Giant Leeches" with "Bucket of Blood"? I would have paired it with "Attack of the Giant Crab Monsters" instead.
I saw a dusk-to-dawn Roger Corwin/Vincent Price 5-bill at the drive-in. They burned the same castle (made of 2 X 4s) in three of the five films. It was great.
The Masque of the Red Death (1964)
The Haunted Palace (1963)
The Raven (1963)
Pit and the Pendulum (1961)
The Fall of the House of Usher (1960)
It may have been The Masque of the Red Death (1962) though, now that I think about it. (who else could have got away with making the same movie with the same star only a couple of years apart?)
Yes, this is vital information when planning the size of your amplifier.

Ahha, Anthony Holton, the man himself. Sorry for spelling your name wrong, I tried to recall it from memory.

Thanks for your replies; itís always nice to hear from the designer himself! (One of the reasons I think highly of Nelson Pass)

I suppose you are right about the feedback thing, I couldnít see the speaker output, so itís unfair to judge.

Could you comment on the pros and cons of the two 1N4936 diodes?

Two more questions I have about the amp isÖÖ would 0.25k/watt heatsinks be adequate on one amp module for normal use? And will 82 volt rails be OK for around 380watts in to 8 ohms without modification?


I saw your comment about the bridging of these modules, as I understand it two bridged AV-800 will power almost 2 KW in to a 4 ohm load but this would not be suggested as it will exceed the SOA limits on the output, because each amp is seeing a 2 ohm load, correct or not?


Thanks very much

My wife not only tolerates the incredible amount of
audio junk (none of it finished looking) but she also
arranged for me to have lunch with Roger Corman
two years ago. He is one of the smartest, nicest
people I've ever met, and when you consider that
most of Hollywood's best stars and directors owe
him their start, he needs an academy award.

I'm still waiting for Attack of the Crab Monsters, which
I'm hoping will be paired with It Conquered the World.

Your quite right of cause the SOA is exceeded at this power level.
Dropping the supply down to +-70 volts would help in bridge mode. Yes the AV800 would work fine without modification on 83 volt rails. Not so sure about the power o/p though. 380 watts might be expecting a bit to much.
You could expect about 320 watts.
The diodes on the o/p are there to simply to help swamp any Back EMF that might appear on the o/p from say a large driver or drivers or line transformer.

And Nelson what on earth are you going on about What's this Attack of the Crab Monsters?

Regards

Anthony

Anthony, thankyou very much for your reply. I am getting about 35 IRFP240's to match up, do you think this would be enough to get 2 matched amp sets at a pinch? or in your experiance do you need much more to yeld 2 sets?



Nelson : Does your evil twin also have a evil amp factory? maybe he designed the CLAW

I would get at least 50 pieces, it's always nice to have a few spares.

It will be cheaper also per device.

Sounds like Nelson is a Star Trek TNG fan.
Excellent!

Cheers

Anthony
