Time-Saving Methods of Rescuing IR3109N OTAs from 80017A Wafers

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2025

Today I am sharing spilling the beans on my 80017A wafer-stripping and chip reclamation methods. Over time I have developed my own system for improving the speed and success of reclaiming coveted IR3109N SMD OTAs in decent quantities. These OTAs are used in my 101-VCF, JP6-VCF, and JU60-VCF eurorack modules. Even with time-saving measures, I easily spend way more time reclaiming the chips than actually building these modules. And the main reason I call my endeavors a labor of love, it's all for you my friend.

Rosen Sound Synth Demos & Restorations

Published on Jul 28, 2018 Rosen Sound

This one in via Soviet Space Child.

Playlist:
1. Oberheim OB-X - Rosen Sound Demo

The OBX was the first major "answer" to the Prophet 5 synthesizer, and at least in our opinion, was the best answer anyone could've given.

The OB-X is based on the basic design of the (S)ynthesizer (E)xpander (M)odule also from Oberheim. Like the SEM, it features two discreet VCO's with saw and pulse, two envelopes, and the low pass section of the SEM filter. It also added noise, a release control, and cross modulation (similar to the Prophet's cross mod). The prophet's cross mod was a bit more dynamic, though. A flexible LFO section is also featured.

None the less, the OBX is in a species all of it's own in many ways. It's one of the very few mostly discreet programmable polyphonic synthesizers, and more than that spec, it sounds unique and absolutely marvelous.

Our unit features encore midi

Book your rental package with Rosen Sound and see the rest of our synth catalog at www.rosensound.com/rentals

2. Moog Minimoog - Rosen Sound Demo

3.SCI Prophet 5 - Rosen Sound Demo

In a lot of ways this needs no introduction. One of the most iconic poly synths ever made, and the first synth to offer true programmability with polyphonic architecture.

The Prophet 5 offers your basic amenities in a poly synth with 5 voices each with 2 VCO's, a low pass VCF, a VCA, two EG's, one LFO with multiple wave shapes available, with POLY MOD as the icing on the cake. This lets you make FM type sounds and is part of what makes the prophet 5 unique.

Our unit features factory midi

4. Oberheim Four Voice - Rosen Sound Demo

This in our opinion is one of the finest synthesizers ever made in terms of overall sound. The features are of course many and the synth as a whole is very flexible and powerful, but the sound it outputs is nothing short of mesmerizing.

The FVS features 4 Synthesizer Expander Modules (SEM) each representing a polyphonic voice. This means for one patch, each SEM must be setup identically. This may seem like too much, but it's actually a very enjoyable process that causes you to think different about the patch your making, the polarity of your modulation per voice, and subtle differences you can set.

The synth can also be used in a powerful unison mode, allowing each SEM to be adjusted separately for a crazy 4x dual oscillator synthesizer each with a multi mode filter to be fired at once.

Each SEM is as or more powerful than your standard mono synth, featuring 2 oscillators with saw and pulse each, PWM, FM, 1 LFO, two EG's, a bi-polar filter modulation control, and the sweetest Oberheim filter ever made featuring a bandpass filter and a sweepable LP-HP filter. These filters are special in the way that when the resonance is turned up, there is no loss of volume or low end.

Additionally, our FVS is an early model with no programmer (a feature loathed by many anyway). Instead, it features 2 dual mini sequencers with a common clock available. This means you can do 8-step 4 note poly sequencing between the four SEM's, or split the keyboard with one sequencer playing 1 SEM and 3 note chords on the other side of the keyboard.

Functionally, our FVS is very much in tune and has been stabilized to survive travel and tuning consistency. It is in tune as soon as it's turned on, and we provide a quick start guide for our rental customers to learn how to easily program and tune the machine.

Our FVS also features MIDI in via a modified YARN's module installed inside. This allows through basic midi and if desired (more complicated) midi scripts to play it polyphonically (default on boot), sequence each SEM assigned to a separate channel (enabling MPE), or played in Unison. All of these features can be harnessed by utilizing SYSEX or the Yarns editor, all which is provided on a thumb drive for rentals.

5. Moog Memorymoog - Rosen Sound Demo

To start, let's forget the internet-lore or an "unreliable" and "impossible to tune" machine. Our service shop is known worldwide for our work on Memorymoogs and stabilizing them for real production use.

Now, let's introduce you to (what we consider) the pinnacle of Moog synthesizers. With 3 oscillators + ladder filter per voice, flexible and intuitive modulation, and a knob per function, the Memorymoog is not a force to be reckoned with, and is in what we consider to be the top 3 best sounding synthesizers ever made.

From lush pads, 18 oscillator unison leads, heavy bass, and even gentle timbres, the memorymoog is sure to be a staple piece for your session in any genre on music. Plus it has everyones favorite feature: an arpeggiator!

Our rental memorymoog will arrive with an expression pedal and 12 custom patches (87-99) made by our resident in house programmer, Eli Goss. These 12 patches are the juice that will fuel modern productions to achieve sounds unobtainable by any other synth, with plugins not even worth a mention.

6. Oberheim OB8 - Rosen Sound Demo

One of our staple synths in the collection. The lore of the OB8 is that it's a less-exciting OBXa, however, with some choice mod's which we've done to ours, they are sonically identical.

The OB8 is one of the most flexible synthesizers available, which includes deep LFO routing from the front panel, and a PAGE 2 function that transforms every knob and button on the synth to do even deeper modulation, including quantized LFO's, musical "OBXA" style detuning, envelope routing, and more.

Additionally, our OB8 has been fitted with a Pratt & Read keybed, which brings the true feel of American poly synths to the experience, while also having the amenities provided by the B5 EPROM including factory midi.

7. Sequential Circuits Prophet 10 - Rosen Sound Demo

The Prophet 10 is more than just 2 Prophet 5's in one box; featuring an active EQ per voice, deeper modulation, and more performance capabilities with it's dual manuals and CV pedal inputs. This prophet 10 also features midi in and out.

8. Oberheim Four Voice Sequence

You could do an entire score with this #oberheimfourvoice. With quad poly sequencing and split modes the sky is the limit. Available for rent through us! Contact us for rates and availability. And yes, it has midi!

9. Prophet 5 Rev 3 Restoration

10. Juno 106 Multiboard removal

11. Juno 106 80017A Chip Failure - What To Check

In this video I go over a couple things to check not only to see if your 80017A chips are failing, but also other potential failures of the juno, including failure of one of the MC5534A dual DCO chip.

This video also applies to other models, such as the MKS 30, HS 60, GR 700 and some others.

The tech who worked for this JUNO-106 is a collaborator of this first acetone soak project, who supplied a bunch of sample ICs and some technical info either. It was 9 years ago. [posted here]

After more investigation we realized just uncoating won't bring perfectness but some more work required. Please don't ask how but understand that top class restaurants won't disclose their recipes.
Now the error rate is as low as other standard ICs in this synth."

Analogue Renaissance at SUPERBOOTH - Analog distortion for the TB-303 and pretty much everything else

"TS-303 GT Acid Screamer prototype

Totaly bonkers circuit design with Vbe multipliers, Gyrator, Capacitance multiplier and Negative Impedance Converter in a feedback loop with ridiculously high gain.
Features:

- Jumper selectable input impedance 50k - 500k Ohm
- Variable input level: From nothing to +40dB
- Variable output level: 0 to 8Vp-p.
- Tuneable Symetry of the distortion. From perfect symmetric distortion to keeping bottom or top half of the signal intact while obliterating the other.
- Tuneable Dynamics: It analyses the volume enveloppe of the input signal and can restores this on the output signal. This from zero to doubling of the original dynamics.
- Switchable between overdrive and distortion
- Frequency selective distortion: Only distort certain parts of the spectrum, while keeping the rest itact. 2 frequency selection knobs allowing highpass, bandpass, band-reject, lowpass distortion. Do not confuse this with filtering of the input or output signal. It happens in the distortion engine itself.
- Turbo mode: Self-oscillation happening only at the highest clipping levels. Still exploring the posiblities of this one, but it already made me mistake a 606 for a 303...
- A rack version will also be available

AR3109

Replacement for the IR3109. Sounds and behaves exactly the same.

It even does the distortion that happens in the MC-202 and SH-202 when you run them at low voltage or almost empty batteries.

It's also DC-accurate. So, it also works in the portamento circuit of early Jupiter 4's.

Custom Colored Roland Juno 106 Vintage Keyboard Synthesizer w/Blue Meanie Mod

Custom colored highlights & buttons.

via this auction

"Up for sale is this Roland Juno 106 Synthesizer in amazing condition.

Two slight details to mention. The 4th F# key is responsive to slightly stronger pressure than all other keys but it's not a big problem and does not affect overall functionality.

The second detail is that, like with many many other Junos, the Chorus is very ( and I do mean very) slightly noisy. However, this is not an aesthetically displeasing sound. It sounds like distant ocean waves (it's technically white noise in phase). But this can be easily fixed.

These two details are the only reason why I put this synth under "Good" rather than "Very Good or even "Mint".
Everything else works absolutely perfectly & sounds incredible. Has the Blue Meanie Mod by SynthSpa (Which in no way change the sound of the original Juno, it's just more stable, and looks spanking.)

Below are what the restoration service does:

Power PCB rebuilt - Large electro caps replaced, new 3 prong receptacle and new standard IEC power cable.
