Taiwan switch

Differ with 5E3 20w:
V1 12AX7 instead of 5E3's 12AY7 for more preamp gain
V1 cathodes separated to reduce channel interaction
V1 cathode resistors 1k compared to 5E3 equivalent 1640 ohm for a slightly warm 12AX7 bias
V1 coupling caps reduced from .1uF to .022uF to trim excessive bass frequencies
Local negative feedback from phase inverter plate to grid

Helps the phase inverter deal with the added gain from the 12AX7 V1 by reducing nasty cathodyne phase inverter distortion, tightening the transition from clean to distortion and slightly reducing gain.

Phase Inverter plate load and tail load resistance is increased from 56k to 110k to add headroom

Phase Inverter cathode resistor is increased from 1.5k to 4.7k to cool the bias and make sweet sounding asymmetrical cutoff clipping more likely

Phase Inverter Balance Control

The circuit allows control of even order harmonic distortion generated by phase inverter imbalance. Add imbalance to fatten the clean tone or balance the phase inverter to smooth out the overdrive tone
