Note: I did a bunch of
updates to the original pedal #1 on 11/12/2005. The changes
are noted below. |
Left: I updated this
board by adding grounds from the Tube mounting screws to
the main ground buss. I used #6 ring terminals and ran two
wires to the ground lug. See
<-Socket grounds.
I also updated a couple wire runs that are not shown in
this photo. The wire from the center of the volume pot pops
up through the board right next to the tube socket and goes
to pin 7. The filter cap wire that goes to pin 6 on valve 2
pops up through the board right next to the tube socket.
Both of these new wire runs can be seen in the photo on the
right, they are noted as <-New |
Right: The relay was
eliminated and the hot switch mod is wired full time now.
The noise level was reduced a bunch by doing this.
The 7812 voltage regulator was moved and bolted to the
chassis for a heat sink. See 7812
Ground wires were shuffled around and some were
removed or condensed. The chassis is tied to the main
ground buss through the volume pot. The volume pot body has
a jumper wire soldered to the back of the pot that is
connected to the black pot ground buss wire. |
