New Construction ST70

Goodmorning everyone
First of all I introduce myself, my name is Giovanni and I live in Italy.
I am a lover of the electronic valves. I have built many amplifiers, both SE, PP and OTL.
Driven by curiosity and even peche I always read positive opinions, I wanted to make the Dynaco ST70.
I preferred that my realization was all original so I bought the new PCB and on the net I found several accessories like: Inductance, clogs and screws.
I made the power transformer here in Italy, In the photos you see of the TU that I had at home, then thanks to a friend I put the original TU Z-326
I enclose all the photos of my realization.

jonny,

It appears to be a 1st class build. Nice work.  What speakers are you using to listen to the amplifier?  Does the amplifiers sound smooth or snappy?

Thanks for all,
First of all I can say that the amp sounds very well and has a great linearity.
It is expressed in the high frequencies with a lot of delicacy and does not come out of the lines and does not screech, very good the soft and controlled low coverage range
In measures I have been very cruel and I can guarantee that the original TU showed no stuarzione.
For the use I am still not entirely convinced whether to make a single-track with Fostex FE 103 that I own, or buy some Pylon speakers that I was able to listen to and I was impressed.
Now I'm making a pré to devote that is the Kondo M77. The source yet to be decided.
Here is the next job

Nice!! Gotta love "Trasformatore"!! The pre looks great also!

I like your power connector!

Thank you guys
I have adopted this connector, to have the possibility to use different power cables

Very nice build. Great job. [beerclink]
