Hi everyone,

I am real curious how everyone is running their power tubes in their C-30 circuit?

I'm running two NOS RCA 5V4s and my center tap reads just under 327 volts.  I'm also currently running TADs.

I nudged my screen grid voltages down a few volts, but other than that, the rest of my power section is true to the layout (I'm running the stock cathode resistor values).  My Ik + Is is right around 38.

What are you guys running in terms of glass and where are you folks at with your measurements - please share?  I think it would be interesting to see where we are all at in terms of dissipation results.

P.S. I know I'm a nerd.

How did you get your screen grid voltage down?

 Ive tried swapping the 100R resistors for 1k but it didnt seem to change the screen voltage much at all, im still getting 333V which is a bit too much for my liking
