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
