Build the Torres All Tube Bass
This is a Newly
developed amp project. for a really great sounding bass amp.
The goal was to develop
pro-level studio and stage bass amp
technology throughout and this really worked out and fit the bill
The Preamp is based on
the Sunn 200
series, one of the best sounding bass amps ever, but the shortcoming of
the Sunn is completely eliminated (the 6AN8 triode/pentode driver).
A new really high tech
differential driver design pushes the KT88 tubes to fantastic frequency
response, way down to 20 cycles and and still retains fabulous high end.
Bass and treble boost
push pull pots are also designed in for some awesome tones and
unbelievable top and bottom end.
With two KT88 tubes it
is about 120 Watts - it can be built with four (or six)
KT88's for, well, a ton of power!!
We have a prototype in our new shop for testing if you are ever in San
Carlos. check it out - it blows the windows out!!
A relatively easy amp to
a great lesson in making a very precise amp. All point to
this layout is in color and fully detailed.
there are compound
resistors and caps
to achieve the calculated precise balance and levels to make this a
clean, solid, strong sounding bass amp.
Also a super-developed power supply with 800 mfd first stage filter
caps - again, get to that bottom end!!
The whole thing is very compact and can be build in a Torres Chassis or
on a project box.
Of course it is more
then amazing for clean guitar and keyboard!!
