Greetings from Hungary

Thanks. I will have some struggles with the translator. HUN-ENG / ENG-HUN is not very good.
A few days ago I made a Class A amplifier. JLH 4W / 8 Ohm, Vcc 12V stable, IQ = 1.2A, output transistors: 2x2N3773. I"ll write more.
Experimentation in progress. (And speaker construction.)
 
Hello!
More about me: my first amplifier in 1992: TBA810AS, then TDA2030.
In my twenties I did a lot of things: PA amps / speakers, class AB, STK4048, MOSFET AB amps, QUAD405 amps, Self-oscillating Class D, Lab supplies, soldering stations, SMPS (hard switching and resonant mode), etc ...
I've forgotten a lot since then.
