Help getting started with Pass DIY amp.

turboyam · 23rd December 2011, 02:11 AM

Hi everyone. Yes, i did search help topics but , a lack (or too much) posts,
did not help me.
I would like to build a Pass class A power amp, around 60plus wpc ( A-75 maybe?), and need help with, where to get the printed circuits boards, components (digikey?) heatsinks? output devices,etc, i'm from Quebec Canada...
I looked at all those project pictures (nice builds in there guys!), and did not see
vu meters... I'd like to install BIG vu meters on mine, any ideas on where to get
those? (a la SAE, Yamaha, Macintosh etc, etc...)?.
Thanks
Pierre

Big, LED projection VU meters, like these?

As your first build, you might want to consider an F5. They do not have the power output you suspect you need, but this amp is a relatively easy project, and a great one to give you experience in the Pass Class A philosophy, topology, and all-the-other-"ologies". It's a stellar, uncompromising amp...!

60wpc into what load? A Burning Amp 3 or F4 will easily scale to that into 4ohms....

i don't think you will find PCB's for A-75.
how about BA-2, aleph-5 or aleph-60?

Into "low" 4 ohm... Did not build or even simulate the speaker system that are going to be matched to this amp yet.
Where do i get those boards?. This is getting exciting

Don't know about the boards, or understand why everyone here thinks they need boards...

Perfboard and point-to-point are great solutions for circuits as simple as these....

Looks like a secret well kept, finding those boards
