my 832 pp amp lives.....
no global negative feedback...
plate B+ is a bit high at 405 volts, screen at 180 volts...
a slight red plate after 30 minutes so i am going to lose some plate B+
i reckon, about 9 watts per plate ought to do it...
how is the sound? i like it....

this amp comes with a phono stage built in....

in all my builds i implement a central ground point

Galing Talaga Master Tony

ina-apply lang ang mga ideas na naipon ng maraming taon
na hindi ako makagawa dahil sa pagpapalaki ng mga anak...
ngayon na libre na ako....maraming pwedeng gawin...
i still have over a thousand tubes to play around with....

a thousand circuits/ideas to try...

this my interpretation of how a 6550 amp is built.
pentode operation with G2 regulation, and big OPT's....

phono stage built in.....

big filter choke, and generous filter caps makes a very stiff psu..

tony · « **Reply #236 on:** Sep 07, 2014 at 08:01 PM »

designed and built up G2 regulator board using the 2SK3028 mosfet
and 120 volt zeners for a G2 of about 400 volts....

tony · « **Reply #237 on:** Sep 13, 2014 at 10:02 AM »

from 6AV5 to KT88....this will be the final configuration for this amp....triode mode of course,
with the KT88, the power traffo and OPT are best utilized...
with the 6AV5 hindi man lang uminit yung power traffo...

pwedeng pwede sa AN's nyo.....
