HummingBird my PCB Revision

[Ciro82]

I revisited the HummingBird PCB layout, separating the input stage and moving the BIAS trim up, plus some other minor updates.
I think i'll go for a test.

Hey there ciro.

I did the hummingbird design for SC.

I have an updated pcb for thst amp that moves the driver transistors next to the output. It hasn't been published as the original was ok, but I Would build the new ones given a choice.

There is no real measurable performance difference but the layout is cleaner. Will shoot you a copy if you wish.

Interesting! I was thinking of grabbing a pair of kits from Altronics to build and have a listen.

G'day Phil

I was looking at building a quad of these amps for a new office system. I'd love to get the new gerbers off you too, if possible.

Many thanks,
William.

Hi Googlyone,

I would love to build one if you could PM the copy.

C6 can be 47-68pF. 1/10th THD @ 20Khz. Just another "badger"....

I would love a copy of the designs too. Thank you
