Here....

coromonadalix:
ooooooh k   they put supplies in parallels ???  you have 3 identicals sections,  sums them up on page 17 ....   

it must weight  around 80 pounds or more loll 

thks

9aplus:
More than 80 pounds :D

BTW This must be one of rare unique combination of
-el tubes (see that regulator on the last picture),
semiconductors like power transistors
and
chips with LCD for Volt and Amp meters  :-+

coromonadalix:
i would say to increase the led resistor a bit,  the led seem very bright ...  or 2 resistors  instead of one, to halve the dissipated power

and since it's on 50 or 60hz   the led will polarize itself  ....  since  you run at half sine, 25 hz should not be perceived by the eye ?? or slightly  ?

not so portable  loll
