Meanman64,Fab ,
I've the red version of boards is there anything changed in the black boards version ?
Not that much. The black pcb was made a little bit smaller than previous version in order to fit within 100mm max length and get special price. However, when you select 2oz copper or non other basic parameter you do not get the rebate. The rebate is good for 1st prototyping exercice when you experiment. It was also done to adjust for easier fit on heatsink.
The changes from red to black:
1- different pcb size so the mounting holes are now perfectly aligned within 2 fins of heatsink (if you drill completely the holes before tapping). Red pcb still fit but closer to fins so more precision is needed.
2- input transistors in closer proximity to prevent having to bend the leads for thermal contact (thermal contact is more important for the USSA-3 with jfet inputs and not mandatory for ussa-5).
3- gate resistor for M2 closer to gate (although no problem has been experienced with red color Pcb)
4- removal of one unused cap
5- 2 mores holes for the USSA-3 to add components to adjust 2nd harmonic level
6- black colour Pcb
There may be a few other things and Project16 would know.
But in general the red pcb really fit for the purpose and both my USSA-3 and -5 are built with it

No, nothing more except the possibility of putting a input apacitor more bulky.Meanman64,

Group buy ended
This is a pertinent question since it has not been determined yet. With 36 sets that makes 72 pcbs. I can order 75 and after that it needs to be 100 so it may not be reached or in a timely manner....also that is already making a lot of work to handle all of these....
So I am closing the group buy right now since there would be only one spare set of pcbs left.
With 72 pcbs, the price for one pcb is 6.50$ CAD (13$ serero set) + protective envelope (2.5$ CAD) + shipping. Shipping price will vary upon the number of pcb sets (weight) and if tracking or not. No insurance of course. Send me a PM for your address and shipment preference and I will provide my PayPal account user name for future payment.
Pcb:
2mm thickness
Gold immersion surface finish
70um copper
Solder mask color: add your color preference to the existing list. That will also confirm again your interest.
Pleas ensure to secure your Mosfet drivers.
