Plexi SE PCB
version 1.0
We
created two file formats for you, Excel and
PDF. We created PDF versions for those of you
that can't open Excel spreadsheets. Although,
the spreadsheet contains hyperlinks to
make ordering the parts a snap.
Plexi SE PCB (Epiphone Valve Junior
Conversion)
This includes almost everything
you'll need to assemble the Plexi SE PCB and
install it into your existing Epiphone Valve Junior
chassis / cabinet. You will need some 600V
rated hookup wire and solder.
It does not include non essential items
like tube retainers, faceplates or knobs. We
leave these as optional items since the look and
appearance of the amp varies from the
builder's taste.
However, we do offer a faceplate design
that can be purchased from BNP Lasers. Refer
to the faceplate section for more
information.
Chassis
Layouts
These chassis layouts demonstrate how the
Plexi SE PCB can be configured to have a Plexi style
or Cascade (JCM800) style
preamp.

Faceplates
We
have created two faceplate styles similar
to the format used in the Marshall 1959
Super Lead (Plexi). These
faceplates are designed to work with the drill
plan and chassis layouts. One permits
the use of the stock power switch and the other is
equipped with an indicator light, standby and power
switches.
We recommend
BNP Lasers
for a high quality
laser engraved finish. We partnered with BNP
Lasers to create high quality artwork for these
faceplates. When placing an order, refer
to GuitarAmplifierPCBs.com. BNP
Lasers already has this artwork in their
computers ready to make your
faceplates.
We
recommend the Gloss Gold (922710) plate
material, Reverse Etched, with a Black
backfill.
Here
are the BNP Laser part numbers.

Just
in case, here are the raw files.
Another option is to take the electronic PDF
file(s) to a printing company, like Kinkos, and have
them print your faceplate on the card stock of your
choice.
Make
certain the faceplate is printed to scale.
The image can not be scaled or "fit to size" for
the graphics to align with the component holes
in the chassis layout.
Of course you can print these out yourself
with your own printer. Beware! Most
printers do not generate prints exactly to
scale. Test your printer by printing a layout
drawing and checking the scale of the layout with a
ruler. If the scale is OK, then you can print
with assurance that your holes will line up with the
faceplate.
