Default SymAsym - The Sequel, AAK's PCB GB

Hi Al,

Thanks for producing the additional THD figures, the latest circuit perfoms pretty well !
Can you also produce the IMD distortion figures?

If you gonna start a groupsbuy count me in for at least 4 boards.

regards,

Piersma

Default SymAsym - The Sequel, AAK's PCB GB

Welcome! This was a fun project thanks to MikeB and his vision to take his already incredible original design to the next level. I encourage everybody to read through the first few pages of the thread “SymAsym – The Sequel” found here

Symasym - the sequel

You’ll get a feel for the design and the flexibility that the design provides for those that would like to do some experimentation.

Here’s the link to the thread that I started to help those interested get up to speed.

My new SymAsym PCB design Rev_1.3

This PCB GB is for the Dual Transistor Version (DTV) found in post #29. The price per board is US $13.47.

For those interested email me your paypal email and shipping address. I'll look into shipping cost and I'll email that information along with packaging envelope and Paypal fee when we get to 50 boards.

Regards,

Al


Moderators can you please append the posts in thread "AAK's SymAsym PCB Group Buy" to this one. Thanks!

Hi All,

The board price is US $13.47. That's for 75 boards two-week price one-week delivery. I figured that having some extra boards for latecomers is probably not a bad idea and helps with the price. Currently I have a count for about 30boards.

If the price looks good email me your paypal email and shipping address, and I'll get things moving along. I'd like to order the boards this week and ship them out before the end of the year if possible. As I receive shipping addresses, I'll look into shipping cost and I'll email that information along with packaging envelope and Paypal fee.

Just wondering how many are interested in the external PS? The external PS can be used to run two amps with a single transformer, or two can be used, one for each amp to add more AC filtering capacitance.

Hi All,

It looks like Mouser and Digikey are out of the 2SC4793. I'd be happy to ship along with the boards a closely matched set of 2SC4793/2SA1837 for each board at the Mouser cost? No charge for the matching. Or just the 2SC4793 alone if you'd like?

Regards,

Al
