PH-1r Phaser
EFFECT TYPE
4-stage phaser
PROJECT SUMMARY
A four-stage JFET-based phaser similar to the Phase 90, but with with a frequency-dependent feedback
control that accentuates the phase effect.

Turn the board upside-down to keep the components held in place while you solder. Don’t try to do all of the resistors at once. You’ll want to stop periodically flip the board and solder everything, then cut the leads using the wire snippers to make room for more. EMERALD RESONANT PHASER... -

ICs may have two different orientation marks: either a dot in the upper-left or a half-circle notch in the middle of the top side. Some ICs have both marks. This shows which way the IC should be rotated when inserting it into a socket (the socket also has a half-circle notch). EMERALD RESONANT PHASER... -

Next, we’ll do the trimmer. Bend the legs outward to keep it in place while soldering.

Now is the time to go back to page 13 and insert the ICs into the sockets. These are the same height as the JFET socket in the next step, so it will help keep the PCB level while that is installed. EMERALD RESONANT PHASER... -

It can be helpful to solder just a single pin at first so you can check the angle. This gives room to reflow the joint if it’s not level with the board. Once you’ve soldered more than one joint, it will be very difficult to correct. EMERALD RESONANT PHASER... -

However, Aion FX projects are designed to be extremely easy to remove from the enclosure for troubleshooting, with no desoldering required—so with these kits, it’s actually much easier to “box it before you rock it”. -

Note the use of two mounting nuts on each of the jacks, one inside and one outside. The inner nut acts as a spacer to set the DC jack flush with the outside of the enclosure. The inner nuts should be threaded as far down as they can go. MOUNTING NUT OUTER WASHER LOCK WASHER MOUNTING NUT 125B EMERALD RESONANT PHASER... -

Don’t over-tighten or you could damage the set screw. But on the other hand, if it’s not tight enough then the knob will be prone to falling off or losing its alignment with the markings on the enclosure.

USAGE The Emerald has four controls: • Rate sets the speed of the phaser effect, from 100 milliseconds to 16 seconds. • Depth sets the intensity of the phaser effect.
