44250: I built the PB250 with an AX1.3 according to the schematic in your post (as it also appeared in late version in this thread). However I reduced the gain somewhat, and the phase maring became to low and caused a slight oscillation. Ostripper helped me to adjust some other components to make it stable (discussed somewhere earlier in this thread). Basically it work very good. Recently I have had problems with the audio sometimes fading away at in one of the two channels, but this I attribute to bad contact/soldering somewhere since the audio back if I knock slightly on the enclosure... Just need to find some time to open the box and do some fault finding

I just have to label it , run the snot out of it... before I trust it for others. I can't blow my one prototype , so I don't fear the stereo pair. (below)

If alex can come close (but prettier) to the style below - let em' at it.
A long board is the one on my single prototype now , below is the "L" bracket deal.

Default Gerbers files for your supersym and The MONGREL (supersym II)

I would like the Gerbers files for your supersym and The MONGREL (supersym II)
amplifiers so that I can order several sets for building and testing. I you offer a group
buy for either of these amplifiers, let me know. I can either have them done at a
vendor, using the Gerbers files, or purchase them via a group buy. Let me know.
