Input jacks with switch for RCA/XLR
Amp boards and pot
Sigma22 psu and transformer, set for +/- 16.2Vdc (gain resistors still socketed).
L channel amp board. Still have the bias resistors (R38/39) socketed, 301R in there currently, resulting in 18-19mA current in the output stage. Also using 2SJ74/2SK170 JFET input. I also didn't populate the 4.7uf Wima caps as I'm not sure there is any point to them being there.
Sounds very good, still evaluating compared to my other Dynalo. Dead quiet. I have only tried SE inputs so far, and don't notice any difference between the switch up (- inputs into the amp tied to ground), or down (- inputs wired to XLR but floating). Gain seems sufficient now that I have the input wiring issues sorted. It will be awhile before I case this, so I just mounted it to some scrap veneered plywood I grabbed from home depot for a buck, stained and polyed.
EDIT: small pieces of clear tubing used as board standoffs, in case anyone was going to chastise me for mounting them directly to the wood
