Q: Is it easier to wire the pots up outside of the chassis on a cardboard with the pots spaced correctly,
or can it be done easily in the chassis?
A: You can wire them in place, it's not too difficult, but I would wire the input jacks outside of the
chassis with the approximate spacing to fit the panel.
TIP: It is easy to solder up the input jacks by putting them "inside out". Use a set of jack locations to
the right of the normal channel and mount the jacks in their final orientation, but mounted outside of
the chassis with the mounting screw inside the chassis. This keeps the orientation and spacing correct
and gives you me a lot of room to solder the resistor, jumpers grounding wire and shielded wires. Then,
when done, remove the completed jacks, mount them correctly inside the chassis and tighten up the
mounting screws and solder up the other end of the shielded wires to the tag strips at V1.

TIP: Flatten or remove the locating tabs on the pots so that they tighten properly on the chassis.
TIP: Sometimes carbon comp resistors are hard to decode the colours. It is a good idea to check the
resistances of these parts before assembly.
TIP: Use insulation tubes from the wiring on the resistor / cap leads around the tubes and pots by
using longer pieces of insulation stripped from the supplied 22 or 20 ga wire.
TIP: There is no bleed resistor in the Deluxe. You don't need to worry about this unless you are going
to poke around inside immediately after it's shutdown.
For safety, unplug the amp, then turn on the stand-by switch for a minute to help drain the caps. If you
want to check them, measure B+ after you've done that. If there is still high voltage there, drain it again.
TIP: Heater Wires: Stranded wire is very hard to twist tightly. Stranded or solid doesn't make much
difference. Solid wire stays in place better once it's positioned and a bit easier to feed through holes. If
they aren't well twisted make sure they are tight against the chassis. You can use 22 ga solid for heaters.
It is rated for more than 5A anyway.
