F6 Amplifier

I wonder if it is possible to build such transformers at home, why not?

that can certainly be part of the fun and the DIY spirit !

but the transformer can have a big impact on the sound quality, usually it struggles the most at the frequency extreme's (although I think some people worry too much about that)

I have a pair of Hammond 1+1:1+1 transformers that I was saving for a circuit like this... hmmmmm :)
 
The use of a IT transformer is often done in the tube world.
In one of my tube amps I tried different phase splitters, the best sounding to me was the one with the interstage phase splitter.
In my tube circuit an IT splitter had the following benefits:
1. perfect balanced splitter
2. works as splitter and interstage coupler, no coupling caps needed to the output tubes.
3. works also as a choke for the driver tube.
4. bias of the output tubes through the IT

I still listen to that tube amp besides my F5 :D

Grts,
Danny

I slaved for my food and bed .... my terror duty was to flip switches off (just on two XA60.5) each time we were going out
so , I was sort of less (if at all ) loved Jack , with one hand more

(low level) signal part of system are/were on all the time

btw. for uninitiated - Jack is official Pass Family Zen Guru ; he showed me The Ocean , barely smiling while observing my hysteria

besides zillion Ikebana styled prototypes I made during yrs (floating service manuals and schmtcs through illegal web mist) , I heard few genuine ones , and I heard Papa's genuine PL second hand system .

:clown:

why you are asking ?

Generg stated noticable difference in Official Drek vs homemade stew J2, and just wandering if that was your expereience as well? How different?

Does Zen not allow for a little joy and is joy not a pure feeling?

if physically properly made , by exact schm , there will not be difference
there is possible difference if active parts aren't in same current range or matching range as Papa does ....... besides that , one need to pick up right one or change some part , using THD meter during both populating boards and powering up/setting procedure

in short - Pa gave us everything needed to make proper Klones
