Jam's Simple Bridged Killer Amp! (split)

[PMA]

PMA,

Nice looking amplifier. Could you post the schematic.

Did bridgeing the amp this way improve the sound.

Regards,

Jam

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

The amp is based on schematic shown here:
http://web.telecom.cz/macura/pm_ab_er1.gif
4 modules are used, 2 + 2 for stereo amp. Bridgeing brings advantage of CMV rejection, it effectively rejects (subtracts) mains components, so it is quite easy to use 1 power supply, which usually brings groundloops (hum) problem.

More can be seen here, partly in english.

I think y'all are suffering from iron-poor blood.

Forget about all those complex circuits. Get your differential input stage and VAS stage all in one using just two lengths of wire and a chunk of iron.

Power supply quality issues? What power supply? 😀

An externally hosted image should be here but it was not working when we last tested it.

Let's invite Susan Parker in here, she knows how to make a transformer amplify ..

Why? The transformer already knows. 😀

Especially very efficient when amplifying POWER ... 😉

Are you heating your own soup Steve? 😉

Aye. But of course I was only speaking of the input/VAS stage portion of the amplifier which is what spurred the original thread.

I'm thinking about it. But it's most likely for Steve's ironwork... 😉

Nah. Just in a smartass mood this morning. 🙂

Ok, ok. I'll leave you pale and pasty anemics to yourselves. 😀

Steve,
I was waiting for that !

I wouldn't argue with Steve, John Curl has already pronounced him as a genius at the Audio Asylum......................😀

Sorry I ment..............so much for the technical part of this thread.

GEEEE.... Jam's in good mood👍 today! 😀

...well, the "spatial stereo" circuit is on a piece of paper... 400 km away from me right now!

Cheers Michael

ps: what is the SW you are using...

 

[MikeW]

Jam in a good mood???

Jam, stop screwing around and post the good schematics.
Jam is always in a good mood.😀

 

[jam]

Guys,

What can I say....................................... 😀

Michael,

What do you meen by SW?

Regards,

Jam

 

[Steve Eddy]

What do you meen by SW?

I think he means "software." Perhaps he's asking what software you used to create that John Curl animation. 🙂

Ah, thought so.

Actually I'm the one who created it using a combination of JASC's PaintShop Pro and Animation Shop as well as Xara for the text.

Ok! 🙂
