I retired ( if that even exists) in 2015 and although love the signal processors, have gone all analog target designs.My 100% push since 2016 has been low voltage tube-ss hybrids.I generally use the tube in fb loop with op-amp and have learned a lot along the way.Pentodes and triodes work just fine at 30v potential (+-15VDC). No positive grid drive is used.My test equipment is upgraded now with Motu M4 for spectra analysis. New scope and linear bench power supplies too.For power amp I use the tpa3118 almost 100%.Maybe one day re-visit the dspic32 but having too much fun all analog.Hot on to do list is re-visit Germanium. Maybe an all discrete tube-Germanium hybrid will materialize.-cheers
