Octals have a bigger plate structure so tend to be more microphonic, as you add gain this might worsen. Depends on the tube and you won't know till you try, give it a try and report back.

I'm no expert but I think the correct electronics term is "cascode."

Enough hair-splitting.
Merlin says to try a 6SN7.

Too much to learn, too little time! Thanks for explaining the difference.

Synchu,

Did you keep the 2M grid leaks at the input?

Don't let that smoke out!

I think I will give this a try based on what's-his-face's PTP layout. I may need to double check a cascaded layout with you guys before I embark, though. I can always build a 5e3 later.

@Structo - yep. 2M at the input. But, I guess whatever larger than 1M is used should be fine.
Didn't try a serial arrangement, but its an easy mod and can be put on switch so once I get off the HRM, I am (very) slowly tweaking, I would try that.
