Cool pics of my diy-proj : clone krell-ksa100mkII

For a long time preparation and hard working , here ,I have finished this proj :
the Krell-Ksa100MKII clone .these are some photos , any advices are welcome.

the bias current was adjusted to 500ma , metal heatsinks' temp stay at 50 degrees Celsius .

The amplifier is powered by a 1200VA toroidal transformer , double independent winding which charges 4 * 68000uf/63v RIFA capacitors.
power-supply soft start.

I match output these output devices to within 2%.
