It is worth mentioning that you need 2 transformers for a stereo amplifier (2 channels).
So that would be for me €122+€15 delivery.

Also try to confirm if they can bifilar wind the 2 secondaries. If not, contact me by email.
I had developed another solution with Toroidy a few years back to overcome that.

Send Thomas my best regards.

Notes: This is a tentative list of members interested in a GB for PRP resistors for a EUVL F5X build (1 set = 1 complete F5X build (dual mono amps + PS)). The GB is run by NicMac, but was suggested by EUVL and kindly made possible by Fitzfish (see post #23). I will post more exact information on composition of a "set" (number and values), pricing and means of distribution/delivery when I have this information.

I was asked by PM why I changed the secondary voltage to 16V.

In some countries, the mains supply can vary by some 10% from the 230V nominal.
Going 16V gets us the margin back in case it goes -10%.

In any case we can easily adjust the regulator output voltage, so there is nothing to worry whether 15V or 16V.

Carlos,

may I ask if I can put my name on the group buy sheet for the Toroidy transformers or is this group buy closed? I'm interested in 2 transformers.

I also use transformers from Toroidy (400VA) in my current F5X build and I'm really happy with the quality.

Regards, Uwe
