Title: Vp, Ik readings on your C-30? Just curious. Post by: OldRushFan on October 04, 2009, 08:24:44 PM 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. Title: Re: Vp, Ik readings on your C-30? Just curious.

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 |
