Hiraga 30W class A w/ current source+kubota reg partial kit no resistor two sets

Description

This is a kit of class A amplifier with ultra-fi sonic quality. The design is with reference to the legendary design by Jean Hiraga published in L'Audiophile
. This amplifier is the "Hiraga super 30W class A". With good heat dissipation, this amplifier can deliver 30W(+/-24V DC) of pure class A amplification.
Features : This is our updated and improved version. The low level section is constant current loaded, and fed by good-sounding Kubota regulator. In bench test and listening test, the amplifier has substantial improvement in speed and distortion performance in high frequency register. The noise and distortion is substantially lower. Sonically , comparing to the original design, it has a darker background, cleaner and more tranparency.
We attached some of our bench full power output measurement results in this listing.
The kit includes all the semiconductors and caps except the metal film resistors.
The output transistors are ALSO INCLUDED.
We provide schematic, part list and installation note for the buyers by EMAIL. We also provide heavy duty power supply boards that diyers can put in their favorite filtering electrolytic capacitors. Please check our other auctions.

PCB dimension : 90mm x 97mm
Copper Thickness : 75um ( four times normal thickness !!) tin-plated.
Finishing : Double-sided tracks, double-sided solder resist coating for best reliability.
The kit contains two channels for stereo application.
