SS Amp with Output Transformer - McIntosh MA 6800 (MA6800) Power Stage Schematic

tiefbassuebertr · 12th January 2010, 09:47 AM

Here a not complete schematic diagram drawed some years ago for creating an interface to connect a big outdoor power supply.
Perhaps helpful for inspiration regarded new diy concepts - see in this case also Bob Cordell's post #646 and SQLGuy #647 about
bipolar (bjt) transistor families for audio power output stages

the connection between bases of the mirror s devices is missing..
other than that, the schematic is a classic one that should sound well.

If this connection would be present, the resistor 1K65 is shorted

right...i also use resistors to correct the current mirrors
dc balance , but not this way..im just going simulating this
kind of connection for comparison..
