Not all OTLs are alike. There are a couple of different OTL circuit topologies used over the years (one of which had a reputation for poor reliability). Joule-Electra uses the most reliable and stable OTL topology which is generally called the Circletron. These are not easy (or inexpensive) to build though… differential input stage and floating power supplies require good engineering and execution to deliver great results. We believe Joule-Electra’s VZN series of OTL amps are the best OTL design out there. Their selection of the extremely rugged Russian 6C33 triode tube provides great sound and ensures many thousands of hours of reliable operation (two or three times of that of conventional output tubes). The use of wood based non magnetic chassis, top quality parts chosen for the best sonic characteristics, point to point wiring, use of damping & isolation materials on chassis and circuit boards, continuously adjustable feedback controls, easy to use and adjust individual bias controls, and use of a variac in part of the power supply to carefully maintain the optimal filament string voltage for the output tubes are just some of the things that make the Joule-Electra VZN series of OTL amp’s so special. The proof is in the listening of course and that is were these amps deliver the goods like no other amplifier can.
