EML Modular Restoration Project.
"The first pic is a repeat of the left module panel I'm making to add to the Sequencer compilation. The second pic is the cosmetically completed left module panel.
I had to take the 16" x 24" aluminum panel, lay out the module arrangement and find a point where I could gracefully cut the panel into two pieces. My oven isn't big enough to hold a 24" long panel. That makes the left panel two parts 'A' and 'B'.
The left ('A') side has two Syntar board PMS1's, a Syntar PMS4 and an MMM VC Filter.
The right ('B') side has another Syntar PMS1 board, two EML exponential amplifier modules, two EML VCO modules, an EML VCF module, an MMM 4x Mixer module, an MMM noise module and two MMM Buffered multiple modules.
The graphics were laser printed in reverse image onto Lasertran and applied to the panel. After baking for about 3 hours, I drilled the component holes then, applied 2 coats of satin spray-on polyurethane. After a day of curing, I added the panel components. I didn't melt off the decal this time with IPA. It was a PITA last time and I rubbed off large sections of graphics. The decal adds another layer of protection and totally disappears under the polyurethane.
Most of the circuit boards are attached. I ran out of mounting hardware and am waiting for their arrival.
The Syntar PMS1 boards consist of a Pratt-Read keyboard driver circuit, a gate generation circuit, a glide circuit, an exponential amplifier, a VCO and a slave VCO.
I made provisions for interrupting the keyboard driver and gate circuitry to allow patching of external 1V/O signals and external gates. I also provide 1V/O outputs pre and post glide simultaneously.
The Syntar PMS4 board contains a VC LFO and a sample and hold. The board will be mounted on panel 2-A and the LFO signals routed to Panel 1-A.
Once I have all of the boards mounted, I'll start wiring up the panel controls. Then, get started on the right panel.
