Default PHASE LINEAR 400 SERIES TWO

i am happy to have one of these for service ...

i was wondering if anyone knows who is the designer of this amplifier . Looking at the style of heatsinks that remind very much the Grandson from GAS ..

thanks
Sakis

The answer is in one of the threads on the forum.
I have most of them saved but could not find it in a quick look! Too busy at the moment !

I don't know what is wrong with your amp but if you need to replace outputs than match them......and adjust the idle again. If you need I have some information ......
At the end check it for oscillations and instabilities at clipping....maybe you will need to install some caps to reduce such things.....And finally. If you want to upgrade it be careful. For an example. you can expect some problems if input op amp is replaced with some other type.....
Feel free to ask. I have some experience with those ,,PL,, amps.
Best regards, Taj

AFAIK the Phase Linear series two amps were built after Carver sold the company to Pioneer - So probably had some Pioneer engineers in the differences between the series two and earlier designs - Like full complimentary symmetry and Japanese outputs. Just my 2 cents.

ok ...this got to be some medium state unit it works with LF356 and outputs are xpl 909 driven by an RCA 66546

eventhough in the service manual are writen all available options like MJ15024 or 2SD555 ( very helpfull of them )

Good machine to play with i think ...
i wonder how happy this amp will be if opamps are replaced to something more modern ...

Nice weekend toy for me

kind regards sakis
