Default Thank you Cannonica and A. Wayne

I have made a video using my old Canon A310 (bought brand new from Brazilian free market by 50 USD included memory card)...you see it can record bass.

If you have good bass reproduction into your PC, then you gonna listen some bass.

Canon A310 recording bass - YouTube

Your pictures are professional Martin Limieux ...you gonna be famous...i am glad you are in my thread..one day i will be proud to say that you are my friend.

regards,

Carlos

The softstart is the one from connexelectronic. It does the trick, the only thing is that the hi-current terminal block is small and I had difficulties connecting 14AWG wires. I strip the thread on a screw on one of the connectors. I had to cut the connector and replace that broken connection with a post where I soldered the wire.

The small transfo you see is for powering the standby circuit I've created (bottom left in picture).

Hi Canonnica,

Are the 15R 3 watt resistors installed correctly? I believe the emitter resistors should be 0.47 or did I misunderstand you?

Francois
I was talking about another one. The 0.47R/5W in my case are Xicon 286-0.47-RC

Default New group buy is within our plans.... the one have already felt the need

of a second round was Meanman, the one that run group buy in the smps forum...he want to open a new one at diyaudio.... also Byron was invited but seems he is busy now a days.

These things depends on interest... depends on how many guys show interest to order boards.... we need numbers, quantity of people, because manufacturer pcboard price reduces when we increase the quantity.

Posting your interest you are already helping....the seed was planted..now we must wait... we gonna be wishing others will post they want boards.

regards,

Carlos

Hopefully there are also the errors solved where I'm running up and have posted here on the forum.
Maybe it is better that I sell my boards and wait when the new boards are ready.
I wait first before I sell the boards, don't throw away the shoes, before I have the new shoes ...

Regards,
Rudy
