The main results and targets should match these items:
|The KR300BXLS is an
frequency, high power triode tube capable of producing 15-25 watts of
class-A power. The KR300BXLS may be used in 300B amplifiers,
you will still obtain only 8 watts. Therefore we recommend the
for these applications. However, if your amplifier has
bias, the KR300BXLS will provide more power. Increasing the plate
voltage and current will result in higher power than is obtainable with
other 300Bs. Consult your equipment manufacturer before
the power of your amplifier.
The KR300BXLS features a new ribbon filament construction and the KR Electronics exclusive patent design with 32 cathodes.
As with all KR Electronics vacuum tubes, the KR300BXLS possesses a vacuum of 10-8 Torr, a maximum grid current of 2.0 microampere and absolutely constant emission over the life of the tube.
All KR Electronics vacuum tubes are warranted for a period of 2 years.
All the audio transformers used in this project are Lundahl products and the distributor list is available here
Lundahl is one of the world´s leading manufacturer of audio transformers used in many professional studio recording and radio stations so it has great experience and all these products use a custom audio C-core.
I am using a DACT stepper attenuator instead of the normal ALPS or NOBLE solution, because the the sound is clearer.
The input and driver stage is the dual triode 6GL7 or 6EM7 with high-mu unit and low-mu unit..
About wire; forget the teflon ! Use only stranded tinned copper wire with pvc insulator, and for loudspeakers use the same.A very good quality stranded tinned copper wire could be bought directly from E-Z-HOOK that carries an extensive line of fine stranded and extra flexible wire.
