Operator16,

Beautiful amp.

Joking here but why is the red rca on the left channel? I learned that the hard way too.

But gorgeous amp very well executed.

All,

How much you want to bet he will take it apart to change it? He has entirely too much attention to detail to be able to live with it like that. I respect a person who does more to do it right...

How about my home-made 200 watt jukebox?

Thank!
RCA certainly needs to fix this little mistake.

New modification A + A / B
RMS: 300 W 8 Ohm
600 W 4 Ohm
1200 W 2 Ohm
Gain coefficient: 30 dB
Dynamic range: >100 dB
Damping DC coefficient: 5000 @ 8 Ohm
Peak output current: 96 A
Nonlinear distortion coefficient: <0.01 % within the 20 Hz-20 kHz range
Frequency response: 10 Hz-200 kHz +0,-3 dB

Very nice work!
Great to see Speakon's too

I was a bit skeptical about SMPS's too in the past. But I have had very good experience with them until now. I'm running my Qwatt amplifiers with SPMS500 (Connex) and my latest build with PeeCeeBee amps I'm using SMPS600 (also Connex). Very pleased with the performance, lack of weight, cost savings and lack of 50Hz interference for large transformers.

I'm curious, what kind of SMPS are you using?

Wiseoldtech,

Interesting. Looks good.

One of the nicest looking preamps around that I have seen. Superb job by Skylar88.

Nice, a neat job!
Why do I get the feeling that the pwer supply was raped from a wallwart?

 

[venar]

agree!!!!!!

2x 330W/4R for my home gym

 

[osscar]

very clean look!
p.s. and my favorite screw type !

And something else from production and prototype.

Very nice build, do tell a bit about the construction

 

[inko]

Original is DPA440 (200W/4R).
The author is Pavel Dudek (Upupa Epops).
It's litle bit modified and I used more modern transistors.

I loved his work and miss him.

Hi inko,
Really nice layout.

Will the traces support the currents you'll be generating?

Hi Chris.

Thanks you
I dont speak english very well.
Google translation is incomprehensible.
If you mean white cable, that is provisior.
There is a thicker wire under the PCB.

Let me help Google!
"provisior" = temporary

Hi Frantisek,
Don't worry about your language being rough. Mine is worse so you are doing a lot better than I would be.

I was wondering if the copper traces on the circuit board could carry the high currents this design can deliver.

-Chris

Edit:
Thank you Max!

 

[inko]

All copper traces, for high currents, are well tin-plated and connected by 16A wires.
(rails, ground, power transistor collector / emitter and OUT).
The amplifiers have been working in my gym for nearly two months.
Usually only at 10-20% power
It's a home gym, not an ibiza disco

The figure shows the power supply wires used (brown, blue).
Black and green-yellow was temporary
