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
:-+ :-+
