I am looking nice design & schematics, any help will welcome.
Here You are:
But I do not suggest triode connection as you wanted to build.
This circuit is an UL-connected output stage. It's sensitivity is some 0,5 Vrms for 50 mW out. So with a CD-player having 2 Vrms output voltage you can get some 0,5...0,6 W, while full capability of this circuit is some 10 to 11 W out. This requires some 8,7 Vrms input voltage.
If this circuit were triode connected the sensitivity would be much lower.
To get 50 mW out, some 1,7 Vrms input voltage is needed.
The full power of triode connection is about 6 W. To get this, you would need almost 19 Vrms input voltage.
To get a real SE-amplifier, a voltage amplifying stage must be added before the EL34. Then the triode connection would have some sense.
Any suggestion will welcome, thanks.
ECC82 is more suitable for prestage with very good sound.
And ECC82 is sounding
better and its gain is enough to drive E34L from every CD or cassette player or RIAA....
Could you post the schematic with ECC82?
ECC83 with his sharp sound is only, IMO, for guitar
amplifiers, but not for Hi-End.
Of course....they make amplifiers for markets, for all people that like big gain and big power, with speakers with low sensitivity-83-88 db....This is econ. politic to sellingIf ECC83 had been a tube with "bad sound", then engineers at such companies like Dynaco, Harman-Kardon and Mac Intosh would have noticed this in time and ceased to use it.
