Friedmänner und der Gedanke zum Selbstbau

<< < (14/14)

Gianmarco:
thanks for the reply, but did you also draw a layout for the components? For transformers instead, which ones did you use? Do you have any photos or videos of the amplifier you've built?

dimashek:
I've made a layout, but it's a 2 Channel amp with 2 different voicings, so a lot of switches (9 relais, 2 OptoMos), and smallish area 2 layer PCB.
You don't need to do it that complicated cloning PT-20 only.  ;D

Transformers: power - custom toroidal, 260V AC secondary.
350V plate voltage, 330V screens

OPT - custom (self made) very big one! EI-96 core with 7600 Ohm Raa and 8/16 Ohm secondary

Gianmarco:
Mmmh ok.  ;D thanks .Since I'm not well versed in this regard, transformers with these specifications can be found on the internet? or do I have to build them by hand? Unfortunately, the data sheet the two transformers are not reported on the scheme.
