TO-3 SYMASYM

The current SYMASYM PCBs do of course include a PSU (see attached image).

The "backend" PSU, which delivers the current to the MJE-drivers and output transistors, is a standard C-R-C type

You can choose (via jumper) to use the backend PSU for the "frontend" as well, or use a special (for example LT3062 based) external "frontend PSU.

Gentlemen,

several of the DIYers of my German group-buy have already assembled the PCBs, and the TO-264 SYMASYM is running flawlessly.

I can therefore offer you this PCB without any doubts.

The price per AMP-PCB will be 8.50€. The price for shipping the PCBs worldwide is 3.45€.
The payment can be done via PAYPAL.

If you are interested in a "small-kit buy", consisting of PCB, emitter-resistors (Futaba MPC74 0R22) and output-transistors
(either use MJL4302 / MJL4281 or NJW0302 / NJW0281), please tell me, and I will do a group-buy from MOUSER.

Best regards - Rudi_Ratlos

Symasym 5.3 psu

Hi guys, just build the symasym pcbs together, one question for syasym experts out there, it is better to use CrC psu or ClC psu. I have some chokes from hammond that Im not use anymore for my pass amp and this are 2,5mH 10A with 0,12 ohm resistance. So I was thinking of 15000uf-L-15000uf psu for my symasym. Would this be OK??
