I have a paper copy of the 1st edition of the CMOS Cookbook that I used so often that the pages started to come loose from the binding. It is an essential resource for anyone who wants to work with CMOS chips.
The author, Don Lancaster, has made the 4th edition of CMOS Cookbook available for free download from his site. Get it immediately. Thanks Don!
Another free download, this time from Hans Camenzin who invented the 555 timer chip! The book is called Designing Analog Chips and is available as a free download from the author.
It is possible to make an overdrive on the SoS pcb that has most of the important characteristics of the Ibanez MT-10 Mostortion. It will not be an exact duplicate but the essential characteristics are present.
I have added the parts list and instructions to the support page for the AMZ SoS pcb.
The AMZ Jfet buffer module is back in stock (and out of quarantine!). It is shown in my hand for size comparison. It is about twice the size of my thumbnail. More info on the pcb order page.
