After
we have offered high quality Interstage transformer, the possibility of
building vacuum tube circuit has now changed to next level. Interstage coupling
is ideal device in audio vacuum tube circuit with its unique ability to
transfer signal at incredible life-like with impact and dynamic unheard
of from ordinary capacitor coupling. This amplifier is a good example of
bringing Interstage coupling to be used in push-pull configuration drive
the legendary tube "The 45". Generally circuit utilizing 45 as output stage in single ended class-A mode outputs at 2 wattsRMS with extreme liquide midrange and sweet top to bottom sound; however, once mate with some big loudspeaker systems, 45 SE may have difficult time to control its pace and maintain enough headroom. This 45 push-pull Interstage coupling is the answer. It outputs 8 wattRMS, providing much greater headroom and better ability to control loudspeaker at any frequency range. Interstage coupling removes coloration of capacitor coupling and improve signal transfer so only pure sound is being amplify by the 45 tubes. |
