Gentlemen,

this round of the group-buy is closed now, and I do not accept further orders.
I will wait until Saturday for the last 3 money transfers and will order the PCBs then.

Find enclosed the current status of the order.

Best regards - Rudi_Ratlos

I ordered the PCBs this morning.

I will see if the forecast I did in post #101 will come true.

Best regards - Rudi_Ratlos

When I quoted the price for the PCBs, I assumed that I would order about 35-40 PCBs.
The final order is nearly twice as big, and I would be able to offer you the PCBs for some Euros less,
since I am now in a lower price scale of discount.

Instead of refunding you the price difference, I made up my mind and ordered a sufficient amount of Vishay MKP1839 / 1F capacitors
(they are hard to get, believe me) and will put into each letter 1 capacitor per PCB ordered.

I will moreover ship all letters with a destination other than Germany as "insured" letter (if possible).

Best regards - Rudi_Ratlos

do you mean stable as in no oscillation, or do you mean 2r0 capable, as in driving a resistive test load, or do you mean 2ohm speaker capable, as in not overheating and not blowing up when driving a 2ohm speaker loud?

Don't worry :-)
This amplifier was successfully tested with Triangle Magellan Cello. If I remember correctly, this high performance speakers have 2.5ohm minimum impedance at around 3.5khz.
I don't have such amount of money to spend on Cello from Triangle, but I was very impressed by the combination.

you should ask:
Is it capable of driving 4ohms speakers, or can it be used to drive 2ohms speakers.

Then we can answer sensibly.
