i'm an idiot ! i'm thinking about only SERIES, not PARALLEL
for the parallel, i still use a 300VAC ?
Thanks a loti'm a n00b

I guess you can do it with a single 300VA (it doesnt matter if its the 2x18V or the 2x35V) If its a good quality unit it should be ok. I am using two pcs 2x18V, 300VA's in mine.
n00b's are very welcome

Where i can look ?
Thanks a lot
Maybe someone closer to you can answer that
Buying two of those with 2x18V secondaries is a very good choice.
You can build many of the Pass amps with such a pair. Almost all of the PassDIY and F amps use them
VAC = alternating current voltage
VA = voltage times current ~power
Rail voltage of the V9 is 50 volts, 36Vac rectified.
2 Amps times 50 volts = 100 Watts.
150VA works, but is not advisable, a 225VA would be the minimal transformer value.
300VA is more common, price difference between a 225VA and a 300VA transformer is not worth the saving.

i did a lot of order from this site... they have a very good things.
But, i've found a great transformer factory near my homeplace that is awesome.
For 2x300VA i'll pay only 100 euro and they surround the transformer with a special EMI foil that is a manna for audio equipment.
Thanks for the information anyway.

same place....that was just an example...there are 4 pages of them.
....but this is 500VA, not enough?
you could allways use 2x300VA like these:

Very low noise, makes shielding not really necessary.

This is what I would buy:

One 500 VA cost much less than two 300VA, unless you want two monoblocks.
