My new amplifier:)

[whee]

What do you guys think of my new amplifier?

An externally hosted image should be here but it was not working when we last tested it.

Some specs:

2x80W 8 Ohm, (Smartkit )
Velleman speaker protection
800VA Toroid
4x10000uF

I use a VERY cheap Eltax AVR-280 Reciever as preamp. (modded)



The next step is to add 3 more channels. This will then be my heart in my (almost) selfmade home theatre system.

Great job. How does it sound?

Is that your handkerchief bolted to the top of the toriod? 😀

 

[whee]

It sounds great! I love 2n3055 🙂🙂


I couldn't find the original top to the toroid, so a just had to use a bit of 4mm alu...... Not quite as nice, but it works 😀

Interesting heatsinking. How well does it handle the dissipation at full load (~80W sine wave output)? It's a very nice-looking amp. How does it sound?

Nice little beast. 80W sine? Out of 3055?When can we expect to see its schematics?

I saw the boards i done

Very happy to see something alike the board scratched in squares, i have been using since 1970!.... in Normay!... right now there is my "fingerprint"!... no matter if do it after read my "New and old way to assemble electronics" or not.... i am dancing with hapiness to see them in your pretty amp.

Music is "I feel good!"

Can i see schematics?

Please, if you can, send it to me, or place it.

This is a kit from smartkit denmark, and it isn't 80w.(typingerror) 😱

This is the specs: 60W/8Ohm or 80W/4Ohm (+-40v) (i use +-48v)

But anyway, i have made an ampilfier i'm satisfied with. Watts isn't the only thing to consider anyway.

I compered it with my brother's denon 1604, and we both simply loved the sound i this one. Good "old fasion" sound 😀

It sounds great! I love 2n3055 🙂🙂

I built a couple of amps using the 3055. Everything about those kits was against conventional wisdom, like it had very low feedback, quasi-complementary OP stage and then the 3055 themselves...

But I tell you that 50w amp sounded sweet in the midbass and lower mids.

Hello dear friend Whee

"We" want to see schematics "Whee", if you can not, "we" will fell bad....but "we" will forgive your (hahaha)

And finally🙂

An externally hosted image should be here but it was not working when we last tested it.

i believe that is a quasi complementary with baxandall correction diode...is it a class A design?...no current mirrors for the input or even degeneration resistors...bootstrapped VAS too...very interesting..

LOL, Thats exactly why it probably sounds sweeeet!
