As I am slimming out my DIY projects backlog due to the lack of time building all the stuff lying around I will post many undone projects and PCBs I collected over time.
Next in line are 4 Symasym Boards designed by Rudi_Ratlos.
Offering a set of green Symasyms
Both versions include a speaker protection section. I am offering every set with a matched quad (matched by Rudi Ratlos) of OnSemi NJW0
65€
+ shipping + PP fees

- Green Version comes without dedicated rectifiers on board (so you need an external rectifier) but the option (via jumper) to power the frontend with included PSU or separate external PSU

In case someone needs more PCBs I have the original Gerbers from Rudi_ratlos and about 40 matched NJWs for about 8-10 channels.
Up. Still have the combination of Green and Black PCB incl tightly matched output transistors available. Price drop to 50€ + shipping + PP.
There is absolutely no sound difference. Black just has onboard regulators than can easily be bypassed.

Schematics for Black variant can be found by searching for Rudi ratlos „Symasym Black beaty“, schrmatics of green board are at my hand.
Up.
I can offer another Set of green PCB with matched NJWs
Same price as before: 65€ + shipping + PP

Still available! I can offer matched small signal transistors on top for free as I recently matched a big stash of them (from building 7 symasyms). All you need to add is matched 2sks for the TO92 transistors.
Up. Set of Black PCBs with matched NJW Output Transistors and small Signal Transistors (besides input pair) for a total of 60€ + shipping + PP
