LCR phono, last one

[waltube]

Hello,

in photo the last LCR stage "full trafo", two stage/channel.
The coils for LCR, step up and interstage are made custom from Eltra Torino , in Italy.
The trafos for tube are from Sowter with Ni, ratio 4,5:1 , custom made
The power trafo from Fiat Transformer in Roma

The start point was this proto with full Tango trafos ans EQ2L

But they are scarce and expensive so I work on alternative also for tube.

A very interesting exercise.
And the name of it is LiberTango ( also a reference for Astor Piazzolla)

In the full configuration there are 10 irons for signal and 4 irons for supply
The HT is ss stabilized with the possibility to swap in the C-L-C filter after the two GZ32
