CIRCUIT SALAD Hybrid by Whammerdyne

Our latest ground breaking achievement in the world of DC coupled hybrid amplifiers. We marry years of our cutting edge renowned technical designs into the worlds first DC coupled tube hybrid. Not just another ho hum hybrid design. True class A Triode tube front end, DC coupled to a Quasi Complimentary solid state output topology. What does all this mean to you ? extremely faithful reproduction of all the music’s soul, dynamics, harmonic richness as well as an iron fist with solid bass and explosive dynamics. Transient speed that is nearly perfect no more slewing of the leading edge attack, phase shift is near zero in the audio band, no more smearing of details and with our “dark” noise floor that will have other manufacturers jealous. The absolute and astonishing reproduction of the full music spectrum is fully realized. Our truly DC coupled design removes the veil that all coupling capacitors exhibit. Power supply regulation for critical front end circuits is by ultra low noise regulators. Main rail power supplies have huge reserves by today’s best electrolytic capacitors that are fully bypassed by tight tolerance polypropylene capacitors giving rock solid performance at any dynamic levels with all the rich harmonics fully realized, sound-stage presence is fully revealed.  We can go on and on gushing, but in short over our 10 years of design and product development bring you top of world class performance at a price that brings it to the hands of the mortal audiophile. This this is an absolute true breakthrough product. We easily will challenge any and all comers at any price. This folks is that good. “Once your hear it, you can’t unhear it”

The finest “True” Hybrid amplifiers on the market



  • (Dual) Toroidal electrostatic and magnetically shielded Left and Right main rail power transformers. (separately fused)
  • Dual RCA Gold plated/Teflon source inputs, selectable (Input 1 and Input 2) by Gold plated contact paddle switch
  • LED precision Digital meter with integral microprocessor. Gold plated toggle switch allows for Left channel, Right channel selection and center Off. (Center off shuts meter off for no noise.)
  • 5 way Gold clad speaker binding posts
  • Precision “ALP’s” Blue Velvet stereo volume control selected for tight tracking
  • Dual 6CY7 vacuum tubes (Dissimilar section) matched pairs. Triode sections used in pure Class A operation
  • Front end sections run an all precision regulated power supplies with independent transformers for each channel (separately fused)
  • Windows comparator circuit for displaying DC offset and making DC offset adjustments via top panel LED digital meter.
  • Auto input muting should a tube short or fail and during initial warm up cycle
  • Audio output limit in event of overheating or extremely low impedance loads or sustained long duration high output events
