wah wah! i like this setup isbi boy!
tnx...
thats how we set up amps here in our place...
transformer placed at the center...heat sink on both sides...🙂🙂🙂🙂🙂

variable capacitor in feedback ????? that is really new .... would you care to talk more about it ???? beyond a nice construction ... also nice drawings
wonderfull !!!
Congratulations. I have read your thread about this design, and finally you made it possible. It looks like a nice solid construction. How does it sound? Any scope capture?
Can we see a picture from the front side?
VERY NICE.
Regards,
Regi

Hi Federmann,
on the amplifier outputs are EMC chokes, amplifier produces any RF interference ?
What is the value of the coil ?

Output choke, much simpler and smaller, much less work.

Nice work, Federmann!
What is the reason of those very thick side panels?
Very simple constriction. Excellent cooling, 80 ° C at full power, without a fan. Once the black surface, the temperature will be lower.
As always, great explanation.Output choke, much simpler and smaller, much less work.
Add to the above easy solutions for input / output chokes:

Federmann... I am intrigued... the ferrite component in post #1393.
Am I understanding correctly that you used these in place of a conventional output inductor.
I ask because I experimented with ferrite beads slipped over a 0.22 ohm resistor in series with the output from an amp and as the ferrite saturated at higher outputs distortion even on a 'scope was very obvious at HF. Something an air cored coil doesn't so.
Edit... oh yes nearly forget... great job with it all.

Temperature 80 ° C is on this side panels ?
