Default For Hajame In Carlos' Dx Thread

Hi Hahame,

Carlos is so fast with his constructions he became the first person to build a GEM after me.

He had some genuine bias and stability problems causing output device destruction which were not down to the 'Destroyer' himself; now cured.
Also the first circuit had a fractional mix of class-A and class-AB bias currents at the output stage which were audible; now separated.

Before anyone builds they should read this long page first.


The matching Mar07 buffer/pre-amp circuit has also been fully tested.

Cheers ........ Graham.
