I am sorry for the late response, I missed the post!
I don't know if you can make the PCB and test it, its double sided PCB
please let me know
Hi Microsim, I have an old version of PCB CAD but work very well and 2 layer PCB is not a big issue, let me see the schematics and I will see how to move forward.
As soon will be ready a first version we can evaluate toghether before start to make the PCB.
I do some repair (for friends) of AV equipment (pro and home, SMPS included) and I have a dedicated bench with PC+EMU sound card+ few software, 50MHz Philips scope (quite old but still in well shape), DC dual power supply, 2.5kw variac, JBC soldering/desoldering station (for TH and SMD components), LG function generator, diy 8/4 ohm 2x1kw resistive dummy load.
With my tools I think will be not a problem make the PCB and test it, of course will take time, depend on complexity and what parts of this schematic can be excluded because not really important for a diyers projetc.
