After cavalli stopping doing their business，many cavalli clone such as "solid silver" which is thoroughly a LAu clone and of course LL/LL2T clone are produced on Taobao. just can't understand why cavalli crap are quite popular in china，that's weird !

use 2*75k in nfb loop，will change the closed-loop gain from 60dB to about 57.5dB。 the 500k resistors are used as input load to prevent oscillation when you use a shunt attenuator at minimum attenuation。 +-450v PSU is ok，just pay more attention to grounding。

Woo has just released their new flagship es-amp 3ES，it seems like another woo stuff as before. eh， a 6sn7 as input stage and 2 300b output tubes with so many expensive wires and coupling capacitors，maybe there are step-up transformers in the chassis below i guess

it looks like fake c2m1000170 in the picture，but ones in the alibaba link below is real

Power is obviously higher than dynalo mk2，but But the temperature is high too.

Certainly

in the past few days;I made some T2 PCB and start DIY. The transformer I made using the pure silver line.But the delay starts is a trouble；I don't want to use it.
