Hello, I've been lurking about for a few months on this great site trying to learn all i can, but am now a little lost in all the info. So i thought id just give it a a go. Bought these

on ebay for a good price and found an old av amp. Would the transformer be ok for the amp? and how do you wire it up in the simplest way for stereo use. Thanks for Helping

Just use the two greens and the black for an amp.The others arent split or are too low voltage to be used,just ignore the,leave them unhooked with some insulators on the end ,the transformer mut probably be able to output is full power on any of its windings,for example if the transformer is 100w it will be able to output 100w on any of the voltages but not more than one at a time

ABSOLUTE B**LL***S.
100VA Transformer will be built to supply 100VA over its secondary windings. If it has two secondaries both rated at 50VA then the MAXIMUM power that can be supplied by each secondary is 50VA.
You MIGHT get away with marginally more than that but the redundant winding doesn't magically supply it's current to the winding that you are using.
Problem is that none of the photos show the current rating of each winding, without that information no-one can help.
30-0-30 and 14-0-14
It is likely that the 30-0-30 is the high current winding and the 14-0-14 would be for a pre-amp type supply but we can't be sure.
Even if it were, in an AV amplifier the low voltage supplies could be quite heavilly loaded.

Saiyng that for transformers which dont have a wattage rating on the secondaries,of course the ones with wattage rated secondaries ca only output max their ratingABSOLUTE B**LL***S.

Hi,
Whilst one statement in this thread is "ABSOLUTE BALLCOCKS",
its very unlikely the transformer is a lemon. Use the 30-0-30V
for the chip amps, and 14-0-14V for any op-amp based preamp.
Measuring each windings DC resistance will give you a good idea
of current capability. E.g. using the same wire a 14 V tap would
be around half a 30V tap, but I would expect it to be higher as
I expect it to use thinner wire for that tap. Same with the other
taps, any decent tranny design DC resistance is a good indicator.
