MetroAmp 50W Finished!

Amp building is addictive as I finished my 3rd amp in four months time and loved every minute. This MetroAmp 50W lead may become my favorite. I am extremely happy how this amp turned out with MetroAmp trannies. Crunchy, sensitive, and raw power to spare!
I only had one issue with the DC BIAS supply where the instructions call for a 150K ohm dropping resistor. The BIAS was too cold with this resistor so I substituted 220k ohm and all's well with the BIAS adjustment range.
Here are some pics. I will go back and clean up a few areas like the V1B cathode resistor is temporary. I used modified star grounding which seems fairly quiet so far.
Hats off to MetroAmp as this kit is a winner for sure. Scott
