Hi,I never really drew it out, because it's simple.
It is a simple ECC88/7308 with a choke or CCS load, biased negative minimally (around -0.1V) from a 47R I/V resistor (and the -2mA offset current for digital silence) and with a 10R Cathode resistor. Anode Voltage around 75V IIRC. The one added trick is an "anti sinc" filter using the most primitive methode of a parallel RLC Circuit. Good output coupling capacitor (2.2uF Mundorf Silver or AN Copper). That's all.
Ciao T
