He sourced all the modules, I got the cabinets from Nishant.

Which power amp module is it? whats the power rating? I see total 6 pairs of output transistors which itself speaks a lot about the Beast.
 
WOW. Great Build.
Thanks Srini.

Kindly share a pic, if any, of the amps on the rack :)
Will share once they reach the owner's rack...

Nicely done,the cabinets look beautiful.

Just one thing,are the heatsinks enough?
They don't look too big.
Thanks Shashi, heat sink size is ok... the cab being cramped, have to provide a small fan for exhaust.

Which power amp module is it? whats the power rating? I see total 6 pairs of output transistors which itself speaks a lot about the Beast.
My friend sourced it from an audio WA group he is on... power is in excess of 400WPC, Japan MOSFETs 5200 and 1943

Here is the pre amp build:

My friend having decided that he wanted a pre-amplifier with tone and balance controls, which was lacking in the existing REGA integrated,
I began the search for a suitable project. Rod Elliott’s audio designs are often well regarded so I looked through his list of projects. Whilst the P88 is very popular, I went for the P97 for the on board tone, balance and volume.

I am using one of these cabinets for Shaan's PeeCeeBee build, deciced to use the other for this pre.

The 120 Volts AC Power Supply will yield a Max of approx 230 Watts into 8 Ohms
or
459 Watts into 4 Ohms

Well Built, Congrats.

Do share your friends feedback on the sound compared to his existing Rega Amplifier
