 **Contribution:** Development and implementation. This was a major rethink of the work covered by AVA's [[https://patentimages.storage.googleapis.com/3b/ca/c7/daa969bad4f092/US5017884.pdf|“Fet Valve” patent]] and embodied in their first-generation Fet Valve products.
-**Discussion:** One of the reasons my Transcendence Six design outperformed AVA’s more costly discrete MOSFET hybrid approach was that it used the optimized 12AT7A-based gain stage core initially developed for the Transcendence Five. So a natural progression was to see whether using that gain stage in one of the discrete MOSFET output buffer architectures covered in their patent provided an advantage over the IC-based buffer I designed into the Transcendence Six. In the process of designing the new MOSFET stage, I revisited a number of assumptions made in the original AVA implementation and produced a circuit optimized for this application that was vastly simpler than the one it replaced. AVA thought its performance warranted it being offering as a premium hybrid product.
