Hi Dale,

What would estimate the price will be for the output boards?

Thanks,
Rodd Yamashita

Whose board is that?
After Chad production boards arrived I became even more spoiled. I won't accept anything less than 2 oz, double face with ultra wide traces, vias and all the trimmings!

Grataku,

This would be a second mass Aleph board purchase for Dale (harvardian). It will be based on BrianGT’s latest design.

Output boards:

If we can get to 100 output boards, the price will be <$5.00 ea.

I am going to make the traces on these boards wider and make sure that the resistor spacing is perfect for the RN60/RS5 resistors.

Best Regards,

Dale

Are the driver boards still $45/pair?

Hi Steve et all,

The boards will be at cost which will be ~$10 - $12 ea. (plus actual shipping)

May be less if we get enough interest.

Best Regards,

Dale

Dale if you fatten up them traces on both the output and the driver boards I may buy a couple for the cold days!

Evaas · 2nd January 2003, 07:21 PM

are these the driver boards? i.e. they hold the big mosfets?

I would think so but the link you pointed to was slightly ambiguous with the description. Also I'd assume that you need to order two per channel, no? in that case I'd be in for four. more if the price goes down.

Hello,

Sorry about any confusion:

There will be two boards available.

1) Aleph driver board using BrianGT latest layout. These will be done as a high quality single sided board with top silkscreen and soldermask. They will have 2.5Oz copper (thick) The estimated cost is ~9.00 per board.

2) Output board. These boards have space for 6 TO247 fets, the 221 Ohm gate resistors, and the 1 Ohm high wattage resistors. They have two sets of connections, so that you can cut them in half for lower powered Alephs. These will also have 2.5Oz copper and be single sided. I will widen the traces from the previous version. Estimated cost is < $5.00 per board.

Shipping will also be at cost.

Hope this clarifies things a bit. Sorry for the confusion.

Best Regards,

Dale
