Mr Pass, anything from the CES?

[tiefbassuebertr]

We are showing SR2 loudspeakers and these concept amplifiers which are two chassis monoblocks. 😎

Are there the the good known "X" or "XA" topology inside, a mixture of both or a complete new approach?

shipping would be cheap on those beast's, but getting some one to lift them into your house is another story 🙂


DROOL!!!!😱😱😱😱😱

 

[jacco vermeulen]

Ou La La , a vestibule and lots of ferns.
How very burlesque.

(what's the Rusky mob doing at piccy 101, i wonder)

 

[Zen Mod]

did anyone saw that that Mighty Drek have blank faced box beneath ? 😱

only what I can imagine is few really big Donuts in it .

Papa - give us pic of mighty welding cables between them ..... please ........

 

[jacco vermeulen]

Eer, how do you call something with only half a channel, a Demaural Amp ?

 

[Rodeodave]

Halfway down CES 2010 Preview and THE Show Preview Pre-Show Report, International Consumer Electronic Show Report and Audiophile Coverage by Enjoy the Music.com there is a little bit on Pass Labs.

OT: Why would there be a smiley?

 

[Gordy]

Eer, how do you call something with only half a channel...

A chan.

Looks Like the Pass Monsters came to life? 🙂

Funny thing is that no one has asked yet about the peculiar main/driver board.

who cares ?

I like welding!

 

[tiefbassuebertr]

Funny thing is that no one has asked yet about the peculiar main/driver board.

because nobody knows further about the internal topology (see post #21)

 

[jacco vermeulen]

Fair enough, how many identical heatsinked devices do you see at the input board ? (including the ones you don't actually see)

 

[Nelson Pass]

Are you referring to this?

😎

 

[Zen Mod]

oh boy - triple 7-legged

that means that serious current is flowing through outer ring of UGS

Papa - where is mine welding cable pic ?

 

[Blues]

I see things in triples...complementary differential with cascoding and current sources...

 

[Simon1972]

what's bolted underneath?

 

[jacco vermeulen]

things in triples

Looks like a high power UGS2/3, with ;
- 3 J109/K389 JFETs in parallel for the complementary differential,
- TO220 Toshiba BJT instead of ZTX450/550 cascode devices for the JFET core,
- Cascoded output stages, IRF610/9610 in lieu of ZVN3310/ZVP3310 pairs.

The main chassis appears push/pull, the blind one a SE layout.

dats a lot of little thingys with heatsinks ....... 🙂

Methinks the output stage is also complementary differential (Differential PushPull)...with 10 fets in parallel differential and complementary(UlSy - you'll see)!!! I think you're right the blind one is indeed for more power in Balanced SE Class A...

Mr. Pass any whitepaper on your new concept catamaran battleship amp?
