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....
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

Peter Daniel has the Aleph-J and F2 boards

F4 and F5 and BA-1, BA-2 and BA-3 boards in in the diyaudio store

ask suds for F3 boards

and look at First Watt page
F5 turbo and F6 is coming, maybe boards will come in the store....

it is a nice CRC/CLC PSU. it supports 6pc 40mm caps, bleeder resistors and bypass caps.

There are literally hundreds of threads about DIY builds of all the Pass DIY amps.
Heres one from last year.

he was a pioneer
in producing boards for F4 and F5 before the diyaudio store came up....
I've never seen a bad review of any Pass DIY build.
It all depends on how much you want to spend and how confident you are.
Matching the MOS-FETs is arduous, the more you need matched, the more arduous the task. Pairs are relatively easy, Triples not too bad, The Aleph P4 uses Sextuplets - not a mean task - and you need lots of devices to pick from.
I've got 24 IRFP244s left from my matching process - anyone can have the lot for £24 GBP plus postage.
Most of them make good pairs and even triples - I will supply the data that I obtained when matching mine.
