I'm sure on triode direct thermal only plays the music's best.
You can't, but we believe we are the best direct thermal triode as a device for audio output, no longer relying on vintage tube. This is where we chose is manufactured in the current "2 A3-40".
This sphere is showing A 3 and 2 standards at all by Jimi plate loss but what 40 W, it shows you can retrieve output equivalent to 300 B. Heater voltage 2.5 V and was sparked a larger development motivation, possibilities, since good quality so low voltage AC ignition can be achieved more than 300 B audio tubes.
Pure class A, single-acting "A3-40 2" output stage
"2 A3-40" chose the output tubes are net ensured stable operation using self biased power was realized for the most simple action 3 2 A is A class of single-acting with original features. This "2 A3-40" the original 2 A 3 plate loss 15, outline is around 2 degrees bigger than W 40 W and more than doubled in real. It 30 delivers maximum output of 10 Watts while operating margin less than W.
Spans triode full analog amplifier configuration
Amplifier & high reliability dual triode tube "12AX7" driver Dan consists of analog circuit based on SRPP tube "ECC803". This concise spans triode amplification and unique and concise of has earned the ability to play music full of freshness and vibrant, expressive.
Independent 2 power choke coil configuration
Power amplifier and driver stage adopted the rectifier tube "5R4GA".
Private power choke coils that separate the power supply eliminates input signal amplifier and speaker circuit mutual interference, from the signal micro-level until the signal of high power amplified to clear.

Made in Sweden, Lindahl, output transformer to
Is the output transformers also heavily depends on quality parts. For best quality results selected, considering the many products from home and abroad, our aims are adopted output transformers manufactured by the lender. For audio quality, output impedance is fixed and has 8 Ω specification (8? 16 Ω), 4 Ω specifications (4? 8 Ω) choice at the factory.
Adopted copper foil oil capacitor coupling,
Amplifier & joined driver stage and power-stage coupling capacitor is amtrans corporation organized by the United States and Arizona capacitors manufactured copper foil oil capacitors used. Thickness of a medium-range, elongation and high sound quality combines the delicacy of the region has earned.
