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

Hi Vitaly,
I will offer the PCBs (8.50€ per piece), the Emitter resistors (Futaba MPC74 0R22, you need four of them per PCB, the cost for 4 pieces is 2.50€),
the input capacitor C1 (Vishay MKT 1822, 10µF for 3€) and NJW0281 / NJW0302 output transistors (you need 2 pairs per PCB, the cost for 2 pairs is 9€).
I will not match the output transistors.
Here is a nice article how to do it: Matching Power and Driver Transistors

Patrick and all,
I will close this group-buy coming Saturday, January 7th.
I will then wait until you have paid me and will order the PCBs then.
I will also order the Emitter resistors, but, Vitalica, I will not order any transistors or caps, since there is no interest.
I will update the order list tonight.
Best regards - Rudi

Gentlemen,
I can offer you whatever you want, but I will limit this group-buy to:
1) TO-264 SYMASYM PCB - the price is 8.50€ per PCB
2) Speaker Protection PCB - the price is 5€ per PCB
3) PSU PCB - the price is 9€ (this new (!) PSU PCB will accommodate caps with a diameter of 35 mm)
4) Emitter-resistors - the price is 2.50€ for 4 Futaba MPC74 0R22 resistors
5) Output-transistors - the price is 9€ for 2 pairs of NJW0281 / NJW0302
6) Input-Cap - the price is 3€ for one Vishay MKT1822
This is the topview of the PSU-PCB:

A minimum request for 10 pcs per item is presumed.
This is the current order list.

I will close this group-buy next week.

as I can see, the only difference between the TO-264 and the TO-3 Version is based on the output trannies.
Are there any DIYers who have already build both versions and made comparisons between the two different versions? Is there a difference in sound or is it just a mechanical thing?
