Jam's Simple Bridged Killer Amp! (split)

How about converting it into a balanced bridged amp which could solve the feedback issue.

It could turn out to be the ideal amp..................... ...............any comments?

Jam

darkfeniz,

You do raise a good point. The circuit would work best with balanced drive but you would have doubled the slew rate and almost four times the power (assuming an ideal power supply) and feedback should correct for some of the distortion.

I have a gut feeling this would turn out to be a great amp...........I have been considering this topology for some time......I need to get around to building it.............

Mike,

I woud think we might have to ask Mr.Pass that question.

It just came to me that if we made each gain stage inverting would it not then qualify as an X-Amp.

I ment inherent distortion in the amp rather than the possible added distortion added by bridgeing the amp.

Ok...Ok

How about this................remove all the global feedback apply more degeneration and set the gain by R1.

Should make all the feedback hating diyer's happy.........a non global feedback bridged amp....... .............comments?

Jam

Mike,

Not really................grounding the - input should work with single ended inputs .......


Jam

Mike,

A signal is present across R1 which is the input to X2 which is the inverting portion of the amp.

Jam

pinkmouse,

I do apologise.........you are correct. I guess I got carried away by the possibilities of the topology.

PMA,

Nice looking amplifier. Could you post the schematic.

Did bridgeing the amp this way improve the sound.

Jam

P.S. I need to learn to read Czech....................

Micheal,

You need to tell us about your circuit.............
