Has anyone tried adding a choke to replace the 500 ohm resistor on the screen mode? Most of the available schematics have a choke instead of a resistor and I was thinking about trying it and seeing if it had any significant effect on feel. I think the output transformer is nearing its limits with 6l6s and I’m curious if the smaller voltage drop of the choke might push 6l6s beyond the 40W OT rating. Thoughts?

Interesting concept! Better high-frequency response and less power loss with a choke instead of a resistor might change the amp's dynamics and feel. Be careful not to overdrive the output transformer; monitor temps to avoid damage. Would love to hear about your experiment!

Adding a choke in place of the 500-ohm screen resistor can change your amp's feel and response. A choke provides better regulation, reducing voltage sag and allowing for a more dynamic response, especially in high-current transient conditions. This can lead to a tighter, Sprunki Pyramixed punchier feel with improved note articulation.

The use of choke can make a difference in dynamics by keeping the display voltage more stable, but it can be risky to push the limits of the 40W output transformer, so you need to be careful, sometimes you can try to feel good by playing basketball legends, this will allow you to have a good time.

Hey, swapping out that 500 ohm resistor for a choke in the screen supply is definitely worth experimenting with! I’ve done this on a couple of builds, and it can make a noticeable difference in feel. A choke (say, 4-10H, ~100-200 ohms DCR) will give you less voltage drop compared to the 500 ohm resistor, which means the screen voltage will stay closer to the plate voltage—potentially giving you a bit more headroom and a tighter, punchier response. The resistor adds more sag, which some folks love for that compressed, spongy feel, but a choke smooths out the ripple better and keeps things more stable, especially when you’re pushing the amp hard. ragdoll hit
