Alfa AS3109 VS IR3109N Quick Comparison


Many have commented about my last video why I fool around w/ reclaiming the old chips when Alfa has some remakes on the market. So here's a quick comparison of the Alfa AS3109 remakes vs. IR3109N OTA chips in my 101-VCF tester module. For me the Alfa behaves quite differently with regard to signal clipping and output magnitude. Enough as to not recommend them as a 1-to-1 replacement in vintage synths and the reason I don't use them in my own modules. It's too bad, I enjoy using other kinds of Alfa chips 3320/3340/3350 in other filters and my 101-VCO.

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


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.
