Quad Eight 2520 style gain block ....PCB Help

[Gwaggin390]

Hi all,
been fiddling with a Quad Eight EQ PCB and thought about making the gain stage
"pluggable" so i came up with a rough design for the "classic" Q8 gain stage on a 2520 style board. Note that the Q8 usually uses +/- 24v or +/- 28v

Fist question is, how does it look? anything i should specifically stay away from as far as component placement? Already have some ideas to make it better.

Board is looking from the top down,
Left side is + then - (top to bottom)
right side is Out, V-, C, V+ (top to bottom)

also, where does one buy the pins to go into the board? and is the female also available to make it truly pluggable?

PCB--(can't get the pic to just load...any suggestions?)

Orignal Q8 gain stage (Mic pre is very similar to the API 312)

Hi P,
i found the MillMax stuff on Digikey, but the part #'s don't seen to work when i punch them in and i can't find them on the catalog pages.
are they special order?

Might you know the dimensions? i could look for equivalents in the catalog

thanks

oops , i fixed the numbers for you.

Be careful with the spacing of the metal can transistors, there might be a problem if the cans touch. Not sure if the drawing is to scale.

thanks peter,

it's just a rough idea for now, i don't have exact sizes yet
the pc i'm using is a piece of junk and i can't get much to run on it
(i'm a mac guy) So that pcb design was made using pcb123 software which is only ok at best
