The amplifier is a very important link in the high fidelity chain
and it must be of "low distortion" and "broad bandwidth",
something that many audiophiles know. The essence is not that it is
class A or B, with simple or complex circuitry,
or containing very special or modern components, but that it is quite
This is the fully assembled pcb. We offer those in kits in our Online
shop. We use only high quality capacitors.
Standard version is delivered with the BC transistors. You can update
the kit with the great Panasonic FC capacitors.
Those are better in sound especially in bass tones and much more dynamic.
This version of the Hiraga Amp is very popular amp. With the Output
of 20W you can drive your hifi devices at a powerful rate.
This design is not the LeMonstre even if it looks very similar it
is a different design!
Please pay attention to the voltages, the polings
of capacitors and the correct mounting of heatsink!
The transistors must be isolated! The Hiraga produces quite a bit
heat so an appropiate heatsink is very important.
This Amp is designed for high (1F) capacitors and 12V rechargeable
batteries. Please be carefull with those devices
due to high voltage loaded inside the capacitors!
We offer you for the Hiraga Amp 20W serveral kits and materials.
