main board over view and notes :

 

main board set up:

the main board of the version 3 is very straight forward 

the best route of attack is placing several standoffs on the board to support it from the work surface  as you solder . 

solder the gold plated nine pin (fender type) pcb tube sockets
on the pcb , use tape to secure the pcb sockets to the board.
solder 2 pins on the bottom of the pcb .

after the sockets are all mounted , then you can press
firmly and solder the rest of the pins . 

this way your tube sockets are not tilted to one side or the other.

note : the fender type sockets work best , gold plating
is essential for long lasting contact.

component placement :

component values are listed on the pcb footprints
place the values as indicated for resistors components with an ‘R’
place the values as indicated for the capacitor components with a ‘C’

jump  means place a violet (.7”) or brown (1”) jump wire

example  : R222 IS A RESISTOR

                 C5 IS A CAPACITOR
