Hmm. After all that I see the MIC502YM is obsolete and unavailable! Back to the drawing board.

Great work, Toni!

I'm going to machine a jig today for soldering the output devices on SA2014. What is the recommended spacing for pcb to heatsink?

Input/vas and power supplies complete. Pics soon [emoji41]

Dear Mark,


very good news! Use 8 or 10 mm distance bolts...


BR, Toni

 

[MarkB1]

Thanks Toni.

I made 2 so let me know if you want one

 

[astx]

Ultracool! A jig made from solid aluminium. Wow!


I think we can see you soon machining a complete amplifier case including heat sinks...


Have fun, Toni

...could be a perfect heat spreader too! Tapped with M3?
Have you used the gerber files to get exact distances? And thx for the nice signature upper right corner!

BR, Toni

 

[MarkB1]

Yes, it would be perfect for a heat spreader. Tapped M3 and M4 for mounting PCB. Dimensions from .dxf you sent me by email.

Total machine time was 8 minutes. Better than doing it by hand!

It's actually quite hard to get a good photo. the surface is very shiny (faced with diamond tipped tool)

 

[Kay Pirinha]

Wow! I have to admit that I am deeply impressed!
Best regards!

Looking good Tony, but your are going to have problems getting to your cables against the wall !

 

[MarkB1]

Can't wait to see what's next from ASTX Audio Lab!

BTW, my SA2014 boards are 99% complete and I'm very happy with how they turned out. Soon I can start construction of the chassis [emoji482]

Thx! Monsteramp ...

Thx too! That's why the rack has "wheels".

Thats really fine! I'm sure you will do a chassis cnc machined from a solid aluminium block

Have fun, Toni
