DPA150

hidnplayr · 27th June 2011, 11:00 PM

Hi,

Does anyone here have any info on the DPA-150 monoblocks by vacuum state audio?
Perhaps the most interesting I found is this.
Here, Allen Wright (RIP) confirms that he uses a differential topology and Kathode and Anode coupling 50/50.

I wonder how the circuit looks like..

Nevermind, I found a similar amp (I think) with schematic and description here: tube amp

He calls it ACPP (Anode Cathode Push Pull).
I assume the DPA150 will have a CCS in series with the output transformer for fully ballanced operation.

Anybody here ever used such a topology?
