I have worked close to FIAT (not the cars!!!!) about output and power trafos.
The double C, 0,1 mm laminated was tested for many times in different wiring.
The p-p one are very good; the open loop bw is 40 kHz.
One of the most important test I am checking is THD versus freuquecies at different power, tipical 1, 10 and max .
On last versions it is very good at low frequencies (good L) and high fr. ( low parasitic).
I have a complete test set up with Audio precision AP1 + other equip.
With the custom ones for p-p KT120 I got 58 w on 8 ohm and 82 w with 4 ohm with a quite costant THD vs freq.

Take also a note that they are making also a good toroid trafos for filamentes.
I convinced them to use an accurate stuff.
Normally I use a separate toroid only for services as filaments, negative bias, ecc.
They use a nucleus well coocked (!) and painted wih a special strong paint + a double screen (internal and external)

The dimensions are:
height 120mm
large 105mm
depth 120mm
weigh 3,8 kg
The cost each one is 200 euros + vat (for eu)
This is what Fiat told me; it is a new stuff.
If you will use KT88/120/6550 I suggest the use a ratio 25:1, this means that with with 8 ohm you will have 5000 ohm a-a for pentode connections ( standard configuration).
The secondary is one centerd on 5 ohm.
The nucleus is a V51.
If you need UL you have to ask for this.

New Bartolucci Victim.
I would also like to be added in the list of Bartolucci’ victims. After more than a year with hundreds of phone calls, sms, mail he sent me a fake post office number supposedly that he sent something. Of course I did not receive anything. He is incredibly sleeker and polite but a big liar and fraudster. I'm curious how still he has the cheek and after all these incidents he tries to sell through the site.
