video upload by Synth Tailor Electronics

"Here's a classic ARP 2600 / 3620 Keybed + Eventide FL201 Instant Flanger that were just restored by our shop! The FL201 paired up with the ARP 2600 is such a delight! Lots of love went into restoring the Arp 2600/3620 Keybed. The 1601 sequencer is a replica that functions exactly the same as the vintage sequencer!

ARP 2600 restoration details:
-PSU Rebuilt
-Tantalum Capacitors changed
-Every Slide Potentiometer desoldered, disassembled, cleaned and re-greased (this is no small job, there are 55 sliders to rebuild!)
-Rebuilt entire 3620 key-bed including new rubber bushings, alignment of all keys/metal guides, cleaning of all gold contacts
-3620 rebuild of LHC. New Bourns sliders/adapters added for better reliability/functionality.

ROLAND SYSTEM 100 + MXR Pitch Transposer/Digital Delay (Restored By Synth Tailor Electronics)

video upload by Synth Tailor Electronics

"Heres a demo of some units we restored , the ROLAND SYSTEM 100 (Model 101, Model 102, Model 103, Model 104) + MXR Pitch Transposer + MXR Digital Delay.

The MXR Pitch Transposer M-129, and the Digital Delay M-113 (both of these units are FOR SALE, if you're interested reach out through our website contact form or email)

HISTORY: The Roland System 100 is a semi-modular analog synth from the mid-1970s, a classic piece of gear that’s still got a cult following. It’s got a gritty, warm sound, perfect for everything from deep basses to wild, experimental noises. The setup includes five main modules: the 101 synthesizer, 102 expander, 103 mixer, 104 sequencer, and 109 speakers. Each module’s got its own vibe, but they’re designed to work together, letting you patch cables to create custom signal paths. The 101’s the core, with a single oscillator, a meaty low-pass filter, and a built-in keyboard. The 102 doubles down, adding another oscillator for fatter sounds. The sequencer’s a standout, letting you craft repetitive patterns that were huge in early electronic music. It’s not as complex as a Moog modular but way more portable and user-friendly for live tweaking. People love it for its hands-on feel and raw, vintage tone.

Another Polymoog Lives!! #Polymoog #synthesizers #synthrestore

video upload by synthpro

"This polymoog came to me all the way from British Columbia for a restore. This unit had not worked since 1991 but she sings now. I will never get tired of the sounds of this synthesizer. This was the synthesizer that got me into synthesizers and electronics.

Off Topic but I have been playing a game I got for Christmas called, 'Tunic' and the soundtrack reminds me a lot of the polymoog in areas."

ROLAND JUPITER 6 DEMO

video upload by Synth Tailor Electronics

"Here is a full demo on the Roland Jupiter 6 Polyphonic synthesizer. This unit belongs to Thane Evans, and it over-went a pretty major surgery to get it back to good health. History on the Jupiter 6:
Work done on this Jupiter 6:
-Main issues found were CPU locking up/causing intermittent failures when doing normal operations (moving sliders/random glitchy lights)
-Unit wouldn't accept the Cassette factory presets wav file upload, and would cause unit to crash/freeze.
-Battery Replacement + Socket
-Replaced Corrupt RAM chip (TC5517APL)
-Replaced heavily corroded/faulty Slide Potentiometers/Pots on both Panel boards. Unit feels great now and doesn't jump around the values causing lockups on the CPU.
-Replaced electrolytic capacitors that were out of spec/leaking on both voice boards. (x71 total throughout entire synth)
-Rebuilt Power Supply, hit cold solder joints on connectors and voltage regulators, through out entire synth
-Full Calibration to factory specs, tuning and D/A calibrations
-Upgraded Firmware to latest V6 firmware (previous firmware/eprom was V2)
-Burned 2732A Eprom and installed factory presets
-Hit cold/cracked solder joints throughout all connectors for better reliability in future
-Burned in unit for 48 hours, tested all functions-sounds great now!"

EXTREMELY RARE PPG 1002 for Tom + first ever shop tour!!!

video upload by foleytronics fx repair

"Here is a demo of the EXTREMELY RARE PPG 1002 for Tom. Plus a bonus first ever tour of the Foleytronics shop!!

For those that want to attempt to tune this synth, here is what worked for me:

The trimmer by the regulators is the CV offset; trim for 0v for the lowest key. This interacts with the CV v/oct, which is right above where the two shielded cables connect from the 20-pin keyboard connector. Trim this for 1v/oct, which can be measured at the switched oscillator CV input jack on the back of the instrument. Once these are set, you can move on.

The oscillators are tricky. They each have an initial frequency trim pot and a volt/octave trim pot. However, the initial frequency trimmer cannot be set willy nilly to A440 because their initial tuning frequency greatly affects the octave selection switches on the top panel. What I found to be most effective is to set the MASTER TUNE front panel pot to 0, the OCTAVE SLIDER to the left of the keyboard to the middle and then begin tuning. Note, every trim pot for each oscillator will affect the others for that oscillator so this is an exercise in extreme patience.

First, turn off keyboard control for OSC B and roughly center its front panel tuning pot; set its octave to +3 and put a folded piece of paper on middle C. You are now going to tune the octave selector for OSC A; this part is confusing as there is a trimmer to adjust the octave selection offset for BOTH oscillators, but only OSC B has an adjustment to “match” its octave selection with that of A. Thus, you have to use that trimmer to get OSC A perfect and then match B to A - the method that worked for me was to switch between octaves for OSC A and adjust the octave offset trimmer along with the initial frequency trim pot for A to get a perfect octave selection for OSC A over the OSC B drone.

After the OSC A octave adjustment, it’s time to adjust B’s octave adjustment. Set A to +3, and switch OSC B to +1; adjust for zero beating at the trimmer in the upper left corner of the board right at the edge of the PCB. Then, switch OSC B back to +3 and adjust its initial frequency for zero beating; repeat this until the octave selection is perfect for B.

Now, it’s time to adjust for V/octave for each oscillator. Sadly, this adjustment affects the octave center calibration we just did, so you’ll have to keep backtracking until it’s good. Adjust the V/octave trim pot for OSC A, which is directly to the left of the CV v/octave we did in the first step. You’ll now have to mess with the init. frequency for A along with the V/oct to get the oscillator to track correctly on the keyboard, but like I said earlier, you have now probably slightly messed up the octave selection so you will have to go back and do that again. Then, adjust the tuning of OSC A again and repeat this process until OSC A tracks perfectly and has good octave selection. I couldn’t really get the +4 octave to be perfect, but hey, it’s a prototype and is probably 50+ years old.

Now for OSC B; it’s very similar to A. Use the V/octave adjustment trimmer which is the lower left trim pot on the PCB along with the initial frequency trim pot to get B to track along the keyboard. Again, you’ll have to go back and adjust the octave selection, but that’s not as bad for B because its octave adjustment doesn’t mess up OSC A’s octave selection. At this point, you should be able to get OSC A and OSC B to track the keyboard and the octave selections should be there"
