svetlov:
the continuation of the story Replacing the power supply  :)

soundtec:
That was interesting , I liked the 'hard wire' regulator approach , fast, simple and rugged .
10/10 for for a really fast upgrade to the Fy6600 , no Pc boards just point to point , a couple of nylon p clips to secure the capacitors to deck would have been the icing on the cake , but epoxy probably does as good  .\subtitles would be great

svetlov:
after changing the switching power supply to the linear one, the voltage ripple was significantly reduced  up to 3 millivolts approximately
square wave noticeably improved
The author of this video is delighted with the fact that when using linear voltage regulators to power the generator, the waveform noticeably improved
but in this generator at some frequencies the jitter is noticeable
in the next video, he plans and tries to get rid of jitter ::)

for the model 6800 generators released a new firmware 1.7
I have already changed the version of the firmware of my generator :)

bitseeker:
Thanks for the English-language summary, svetlov. :-+

very interesting, thank you!. by the way wich version of firmware come from factory? it is upgradable? i ask because i plan to buy a fy6800 and appears kkmoon is cheap than feeltech (feelelec), feltech seems to have  firmware 1.6 maybe upgradable to 1.7. thats the reason to know kkmoon version of firmware.

thank you in advance.

best regards

Pio
