i doubt kung palamuti lang yan.
i hope the maker/s won't resort to that thing.
im sure my ckt function ung tubes na tinutukoy nyo.
sir dana with all due respect (share ko lang sir ha
), meron po nangyayari na ganyan.
examples that i've seen so far, a tube buffer that only uses the tube's heater as a mosfet's current source (hence it should be called a mosfet buffer), a tube rectifier that doesn't even rectify but likewise glows. an avr with the center and rear channels at 1/5th the power of the fronts. a tube amp with ss tone controls that can't swing enough output voltage to drive the next tube stage. so for whatever reason, it happens.
as for the av200 and looking at the pics only, those two small signal tubes should be (at the very least) a cathode follower which would make it an input buffer. it could very well be a plate follower but with the cap values (from the posted pics) having 35V it's possible yes but foolish to operate a tube at that plate voltage at the very least.
kaya nga ganyan ka-skeptical si Tony.
hindi naman cguro ganun ka ogags mga gumawa nyan at ganun kababa ang tingin sa consumers.
PMPO daw po yun 200W+200W pero look at the THD, at less than 0.5% pa yun ha. PMPO at less than 10% total harmonic distortion would be a milestone in modern day electronics.
saludo ako sa nag test niyan.
kung me schematics man lang sana, madali yan madetermina...pero talagang mura sya in fairness....
malabo daw yun schematics na ilabas sir. live subject and old school reverse eng'g na lang.
hindi ko kayang gawin yan with that looks at that price.....
hard to beat talaga, even the pure ss amps nila gaganda pa ng case, heatsink. naka toroid pa yun.
