Adding a CRC for SE in relation to adding zener to drop B+

[yello]

I have a single ended Champ type amp that I plan to add an extra filter and resistor stage before the typical "A" node. Helps with noise and will lower B+ a little as a side benefit.

I also plan to lower B+ by adding a zener or two per @JMPGuitars drawing, and want to know if I've drawn this correctly to integrate the two:

The drawings appear to be accurately described.
