I returned from a 6 day trip to Arizona to find the replacement IC’s had arrived, and quickly worked on several ‘problem’ modules to install these and test them out. I was able to successfully test the Noise/Ring Mod and the 2 VCA’s. I was also able to add IC’s back to the already-tested Mixer …

One more red press-button closer …
Yet another order of straggling parts have arrived, this time bearing a red push-button for the ADSR that I had overlooked. The only exciting thing here is that it is the only one of its kind in the project– all other controls are either pots, rotary switches, or toggle switches of some sort. I must …
Today’s Lesson: Don’t order IC’s from China
After some very helpful assistance from some of the folks on the Muffwiggler forum (and Pharmasonic), I’ve determined that all the LM301 opamps I purchased off eBay are bad. I found 3 opamps that I had ordered for the S&H and Mixer units in my 1st round of work on this project that LM301 compatible, …

The First Troubleshooting Success
After a few days of nagging Pharmasonic and many users of the Muffwiggler forums, I have managed to troubleshoot the 1st of my problematic modules, the 707 Amp/EF/Integrator, and this process has uncovered problems in several of the other modules as well. It turns out the LM301 opamp IC’s that I bought are bad. These …
A Temporary Home for the Fleet
I was able to throw together a 3 row 84hp wooden rack after some Youtube videos about box joints and purchasing a dado saw blade. The fleet looks much more impressive in a rack rather than spread out across my desk. This rack is intended for a future project, but can conveniently hold this one …
Builds are MOSTLY together!
I definitely went a little OCD the last week or so while I built out these modules. My goal was to have them completed by October, reality had me building them to be ready by September. This was ultimately a good move, as I’m beginning to realize that a great deal of testing and calibration …
Bronx Beasts at Dragonflight 40
I was able to run “The Handoff” at Dragonflight this year! It was a great start of the con and very low pressure for my 1st official con game. I had some veteran gamers at the table that handled themselves like pro’s. I was worried that the adventure was too short to fill up a …
The Buildening!
PCB’s arrived on Friday, while I was out of town for the weekend, of course. I was able to get home on Sunday in time to build out the patch bay and the noise source that day. Monday was spent with the VCA’s. I built both at the same time, which did help cut down …
Still Waiting on the Boards
I have sorted all my bits. I have separated 1% tolerance resistors from the 5% resistors, then sorted each group into order of resistance. I have separated the electrolytic, tantalum, and ceramic caps. I filled a 40-drawer storage box with IC’s, transistors, trims, switches, sockets, and other parts, each meticulously labelled. I have filled 4 …
The Inaugural Test of the Test Rack!
Ok, This is not quite the VERY first test of my test rack, but the first worth capturing on video. My very first successful test involved turning on the power supply to watch my 2hp MIDI module light up and test its USB connectivity. I was able to get it recognized in my audio software …
