No need! R 8 = 270-470K, only protect you, and protect Cap 220uF when make Supply.

Sounds very interesting. I always wanted to hear a good E182CC output stage. What output transformers are you using?

The only place I can find the CCF50 Dale resistor is from mouser but minimum order is 5000. Is there anywhere else or other alternatives?
