Default Real DIY fun hybrid testing.

REAL DIY FUN .

I want to show a real 6c19p purpose as a mu follwer driver for mosfets in dc mode in this hybride, it is a dual mu version with penthode input.. movie is from a mobile phone so don,t expect huge dynamics, but just a idea of how it sound, use your imagination ;-).
REAL DIY FUN HAHAHA.


I can say it is very dynamic on a couple very old phillips midrange and tweeter. and fast as hell, very sweet (normally this go not together without harsing sound), it seems to go not loud power go into dynamics what is a good thing, it is quality, see square wave 20 Khz with little overshoot what is not important, amp has no corrections whatsoever, a little capacitor in feedback can be used to make perfect square wave, but do nothing on sound.

real diy testing, real fun. - YouTube

phillips midrange is AD5061/504 4 ohms, stronge thing by the way

I go make the schematic complete, it is a double MU-stage version and the sound is I think very good
better then a gyrator-loaded voltage stage -cathodefollower version I have.
