Elsewhere on the forum our friend Rob (n3szd) wants to build a 1000 watt
single-ended amplifier.
On the one hand, I sympathize with excess enthusiasm in a project.
On the other hand, I take no responsibility for the results of posting the
following schematic.
Anyone who attempts to build such a thing is probably asking for trouble.
You have been warned...

wow 🙂
it do smel a little expensive. at $40 pr output device, it will be $1280 just in outputs. and one will need 3 times as many just to get matched sets 🙂 i don't want to think about the total price for a running 2ch amp 😀

And parallel devices should be matched to .1V Vgs or so.
Keeping that in mind, you will note that these devices are not at
the higher end pricing of hockey pucks.

There is a GOD!!!!!!!!!!!!!
Thank you, and the $15,000 I will spend building it!!!!!!!!!!!!
WoW
Just wish it was 300volt rails...
260 seems low.. But I will say this, it looks simple! I need current max is all
I am going to have a few questions, but am with Janet now, mostly has to do with what type caps for the picofarad, P1, is variable bias control? Purpose of Q3, wattage ratings for resistors not labeled. Q4 andQ5 is missing a lead? Think that covers it
Lost more to figure out, especially cooling

going to build this , while asking that type of questions ........ you're going to build your Personal Green Mile .
moi ...... contemplating about 10,000 mW monsters
Papa - wouldn't be beneficial to include emiter/source follower , to feed octet of pucks ?

a more doable version could be: 14 IRFP240 gainstage Devices and 14 IRFP240 CCS devices @0.36A pr device for a total of around 5A bias and +/-85VDC rails. thats about 400W class A @8ohm. total consumtion of about 2KW for 2ch. still crazy amount of power.
That has been suggested to Rob previously. Perhaps it was insufficiently
over the top.
😎
I did a quick calculation, and it should have roughly the same ratios as on
the Aleph 1.2 in terms of drive current and capacitance of devices, so
perhaps we'll see.

okei 🙂 but i guess most would rather buld the lower power version do to cost and not to mention the heat 🙂 on the other hand, maybe a 400W monster F5 turbo would be more atractive 🙂
we don't compromise, why should we. This amp would use 70 irf's per channel, I made it simple. Input power with my supplies is 15Kw. 2kw Rms per channel. That's 8 grand alone in heat, let alone losses in the P/s. It has to double into 4 ohms, it is the aleph 1000, by a different name and a different way of doing it, the schematic is "Simple", yet exudes authority in a way no amp ever did, here is to all the planar lovers! Chernobyl 1!

Again, no compromises, full tilt SET Class A, just like the aleph, no different and doubles into 4 ohms. Really wanted 300v rails though... The "beast"
