I came across this forum while browsing for J. Futterman OTL. Someone had questions about Futterman's H1 mono power amps. Since I and some friends modified these H1 OTL mono power amps in the 80's and adapted them to modern times and still enjoy music with them every day, we are practically quite familiar with this OTL circuit.
