A project with a particular Tube! The product description of
the company Silvercore says it all, so here's a quote:
"The 833c is a large transmitting tube to transmit power
up to 1800W. Audio Amplifiers with 150W in the SE-operation have already
been realized, the effort can pay WAVAC but with a sale price according to a
family home. I thought with the amplifier to a more affordable object of
„kiss“ as the Americans say, „keep it simple and smile“
We content ourselves with a little less power, the tube
should be cut out so rich 300B 20W realize an amplifier of the loose and
doing good apart from the mainstream.
The use of current Chinese production come from 833c tubes are constructed
so easy and enjoyable inexpensive despite excellent quality. When I use the
Vorröhren matched EL34 in the "long plate " version, which give the sound
and force structure.
Speaking of power. The output transformer is sufficiently dimensioned so
that the speaker into the bass range, the full power available.
The sound is loose and light, the trust is not the large tubes so that one
play loosely 300B, which must be heard.
And that is joined by a powerful bass, the 300B can also not known. This
plays a large tube. Kiddie's somewhere else."
