Just to have a reference..
(ignoring compensating capacitor pins 1 & 8..)

Voltage on pin 2 should be the same with pin 3..
2.19V could be down to partially shorted C6 and/or C5 in relevance with Distortion pot setting, BUT, in such a case, voltage on pin 6
shouldn't stay on 4.51V..
(for a 4.51V on pin 2 it should be ok but for present voltage it should almost be hitting the positive supply rail..)
You can check for the above with pot set at its extreme ends while measuring voltage on pin 2..
If you get different voltage readings on pin 2 then check for DC gain (other than unity, due to C5 & C6) inside NFB loop..
(something forms a DC path from pin 6 to GND via R5/C6, R4/C5 AND
pin 6 is somehow shorted to VB..)

Additionally, voltage on JFET Source should be about double, for 2N5457 & 10k Source resistor - in case you've altered device type & resistor value I can't figure the "right" voltage..
(clipped signal voltage, after
Si diode pair, is about 600 - 650mV so on negative waveform is marginally additionally clipped..)
