OK, OK

a) The speaker section of passdiy won't be empty for
long. Kent and I have a backlog of projects finished and
not written. El Pipe-O will be the first out of the gate in
a week or two. Most of the projects are high efficiency -
98+ dB or so.

b) Wayne's passive remote will be out as soon as I
write it. Wayne hates to write.

c) What kind of monster amp do you want? There is a
surfeit of possibilities.

Muuhahahahahaaaaa.

:redhot:

Oh yeah, the crossover is a high priority.

1. A balanced differential like X without the "X" would be cool, but some might shriek at the parts count. A circlotron would be really cool (ever had a chance to ponder that circuit?)

2. Class AB, but high bias.

3. Able to be scaled from say 250W up thru 1kW.

4. Mosfet, naturally.

5. 2-stage, if possible.

6. Bias meter option.

7. Must have really cool intimidating name i.e. Colossus, Atom Smasher, Doomsday Machine, etc.
 
c) What kind of monster amp do you want?

Ummm. How about a Tube section front end driving a Hitachi complimentary pair output section. Class A/B and anything over 400 Watts per channel into 8 ohm loads, oh and at least 3dB headroom, Flat response curve from 10 Hz to at least 25 KHz. switchable NFB circuit (Off, LOW, MED, WHY BOTHER) settings.

If I think of anything else I will let you know :)

Thanks Mr. Pass for entertaining our indulgences.

Straight to the sin bin

well, it's a more efficient amp almost by definitiion in that Aleph type efficiency would overload anyones elec system. So, it's a green Pass machine How about "The Incredible Hulk"

Yes a 500 watt /ch amp is environmentally correct!!

Continuing on the theme... It should be powered (somehow)
by clustered 300w recycled computer switching power supplies.

come to think of it, there are no trustworthy "digital" DIY amps. The Danes are engaged in a catfight about their respective machines, etc.

Even commercially, the Bel Canto digital is a wimpy thang!
So crack the books, it's a new century :eek:


er, I'll just check myself into the Pass Labs Sin Bin here, don't worry about me.

:drunk: :crackup: :guilty: :zombie: :worried:
 
How about an amp that can be built as one 1kW channel or 10 100 watt channels? and biased between a foot warmer and a fondue cooker for summer and winter use? Something that can grow as ones system and curiousity evolves. Something where one can parallel channels, power supplies or capacitance and see how performance changes. Sort of like teaching lab moduals, only not broken.:)
 
Talking about The Claw... a horn speaker...

...is there any chanse that mr Pass Himself has ever listened to a pair of Lowther Fidelio horns? In that case, what is his opinion about the speaker and it´s qualities?

written by a guy who might build a pair of them since they fit in my living room even if my name isn´t Bill Gates. The Claw doesn´t...

So Wayne's passive remote is no longer a priority :bawling:
