The Audio Note Custom EL34 is a very
rugged EL34 Based Tube Power Amplifier operating in Class
AB1. This amplifier provides 35 watts of pure smooth and
warm EL34 wattage out of this unit. The driver section for
each channel consists of an ECF80 tube. This part of the
amplifier is a high quality thick PCB with highest grade
copper tracks.
The power supply uses a huge
Mains transformer and choke along with some ultra fast
Fairchild diodes we use to supply the AC filaments to the
driver and power tubes. An optional Mundorf M-Cap can be
simply connected to the circuit as an optional high quality
upgrade.
All power
supply capacitors bypassed with high quality poly film
capacitors.
Response Audio custom builds each Audio
Note Custom product to order. The prices below are for a
fully assembled and tested amplifier with fully warranty.
".........The new EL34
stereo CLASS AB1 amplifier from AudioNote Kits was designed
by master craftsman Andy Grove of Audio Note UK – This amp
is near & dear to Andy’s heart and he has used many years of
amplifier design knowledge to come up with this awesome new
EL34 tube amplifier for the DIY market! As one customer
recently put it – it sounds ridiculous! (that means very
good!)
I asked Andy to write
me an article on how the design came about – what were some
of the reasons you went with the Pentode wiring instead of
the Ultra linear mode as used in the famous DYNA ST-70 – Its
been about a year of R&D from the development of the output
transformers, the overall circuit design– the prototype
building, the tuning and optimizations of the circuits, the
partitioning of the circuits into hardwired and PCB – the
overall layout of the amplifier, the manual and all the
parts sourcing – the end result is a product of the highest
quality with amazing sound results! At 35W it is very
flexible and running in CLASS AB1 it has many of the
benefits of a single ended sound with the advantages of push
pull!......"
