50 Watt Updates

I’ve been tweaking the 50 watt amplifier.  It’s sounding very promising!

Some of the highlights:
50 watts of power
6L6 or EL34 power tubes
3 12AX7 pre-amp tubes
5U4 or solid state rectified
Sound signature borrowed from it’s little brother
Still just 4 knobs (Gain, Bass, Treble, Volume)
4/8/16 ohm output

I’ve modified the tone controls to beef up the sound a bit to match the greater output power.  I’ve also added a small amount of negative feedback to increase the headroom.  I’m still in the process of tuning this by ear.  I expect to have the prototype done by the end of the year.
