5 Getting the best out of your
amplifier
Thank you for purchasing the Stereo 60 MKIII. A great
deal of care has been taken by our team in the
development, production and testing of this amplifier.
We are sure that you will hear the difference!
WHAT IS THE STEREO 60 MK IIIm?
The Stereo 60 MKIII is a push-pull Ultralinear stereo
integrated/power amplifier, capable of running in
either pentode Ultralinear, or pure triode mode, using
the excellent KT120/KT150 valves in fixed bias mode.
The driver and phase splitting is all triode. The ST60
MKIII may also be used as a power amplifier.
Incorporating our own "LDT" low distortion tertiary
transformers. The pre-amp is a high quality 'Passive'
circuit using silver audio cable and an ALPS volume
control. It is sensitive enough to be used with all
modern source equipment. Its simplicity coupled with
point to point hand wiring without the use of printed
circuit board's results in an open euphoric sound that
is wonderfully detailed and warm sounding.
The ST60 MK IIIm is a third generation amplifier
specifically designed to get the best out of the
excellent KT120/KT150 valves, in this model we have

also optimised the circuit and output transformers to
work with the new Tung Sol KT120/KT150 valve.
The "m" denotes the built in meter which simplifies
the bias checking. When a power valve is working
some of the energy is lost as heat, and all valves
have a maximum dissipation, in the case of the
KT88 this is 40 watts. The new KT120/KT150 can
dissipate 60 watts, a considerable increase which
we take advantage of to generate more power, and
also means the KT120/KT150s are working well
within their maximum, thus giving greater reliability
and a longer life. If you decide to use KT88/6550
we recommend that the amplifier is de-rated by
using a lower HT. Please contact us for advice on
how to do this.
