Mu-Tron Pedal Flanger 3007, Manual

Due to the Morley enclosure’s presence of “predrilled” holes, it is necessary to
fabricate a shim/spacer to properly center the board mounted DC jack.
The spacers can be fashioned from two pieces of etched circuit board scrap.
Drill holes and file slots to accommodate the jack pins in two pieces of circuit
board. Cut both pieces to extend past the two sides and the rear of the jack.
The spacers should be flush with the front of the jack.
Using a file and emery cloth, reduce the combined thickness of the two shims
for a total thickness of 2mm. This spacer thickness allows for centering the
jack with the existing hole and leaves an ample amount of the jack pins
protruding through the flanger PC board for adequate soldering.
Secure one shim to the bottom of the jack with 5 minute epoxy. Secure the
second shim onto the first with epoxy. Now secure the jack with attached 2mm
spacer onto the flanger circuit board with epoxy.
This method of attachment will also alleviate pressure exerted on the jack pins
and solder joints which are the usual points of failure.
