Pass Labs a40 amplifier
Parts & Suppliers list
I think the list below contains
everything needed for the Pass Labs a40 amplifier (except fuses, switch,
and audio connectors). I am relatively new to the area of DIY electronics,
so please let me know if I've pegged anything incorrectly! I haven't
purchased anything just yet, still learning and investigating.

The Motorola output transistors require adjusting the output bias
(original Lambdas are 25 ohms, the Motorolas are 40 ohms), but I'm not
sure exactly how to go about that just yet. I'm still learning here, which
is the main reason I've only been finding sources and not making purchases
just yet.
