The next logical step for the
prologue was to use a directly heated tube with basically the same amount
of output power. The transformers from the prologue can be used for this
amp as well, making it possible for me to make a new chassis plate and
popping on the same iron. In addition I have used a separate
preamp tube to act as buffer for my cross-over filter. It is tapped
directly from the volume control and amplifies about 12 times. This gives
some extra gain to the bass amps as well.
Changed the 83 to a 80 as I
was having too much noise coming from the 83. The 80 is a bit warmer
sounding than the 83 and voltage are quite a bit lower (220V with 83 and
190V with 80). I couldn't get it finished in time to bring to the ETF, the
EC8010 is still too microfonic.
This amp has a seperate output that goes to my bass amps. The tube
can be seen in the pictures between the two EC8010's. It is an ECC84 and
it's input is tapped directly from the pot. Bias is at around 14-15mA, one
section is used for the left channel, the other for the right channel.
