Post your Solid State pics here

Ah so grasshopper... indeed

 

[eesbiboi]

i see there are lots of very nice amps posted here...i wish to build one like those someday...by the way here's my work...

wah wah! i like this setup isbi boy!

One of my vero board amps.

Latest version of an experimental se class-a amp. Left unused for its too clean sound.

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.

Regi

Missing to complete the coating. The sound is very solid and good.

Nice work, Federmann!

What is the reason of those very thick side panels?

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.

 

[Federmann]

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.

 

[PMA]

You probably mean long thermal time constant, don't you.

As always, great explanation.

Add to the above easy solutions for input / output chokes:

3DotAudio Lug Kit for digital [or analog] data cables RF Ferrite Bead / Lug Filters

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 ?

Inductance is 1μH, please do the listening tests.
