I wud have thought this thread would have died an unnatural death by now.
I hope not - I just found this thread and I am putting together a parts list to build one of these.

Well, it takes me a long time to decide what to build, I’m just now thinking about a 6V6 linestage buffer
just wondering about the merits of volume pot before or after the cf, that may take a few months to decide if I’m not careful...

I could say that about some other recent threads, but certainly not this one.

Just a quick question on the 6V6 since you guys know it well. I was wondering about using trioded 6V6 in PSE (a pair in parallel) for an output stage. How would something like 385v at 35mA be? I have some 3.5K OPTS at 70mA. I have a friend who uses 6P6s in his guitar amp at 415v a-k with apparently no ill effects.
Are we talking about 6V6 or 6P6S?
EDIT: skim read that post...my bad.
From the datasheet of the latter, I interpret that Va max of 350V is datasheet max. About 15W total anode and g2 dissipation.
I suspect I'm running then in the region of 11W to 13W. I'm not so sure I'd run 6V6 quite as hot as that. (13W)
I dont have any 6V6, but I do have 6P1P, another tube Koda knows a bit about.
I'd probably run them at a level you are planning, due to their ever so slightly lower rating

I need gain, but I also need lowish Rout. I know there are many ways to do this, but has anyone used the gain version and then connect that to the CF version? Seems like both versions are low noise enough that this would still sound good.
Thoughts?
Are there any negative side effects that I might not be considering?

If going sand, I would think I would think I wouldn't need a HV mosfet solution, as long as I put the buffer after the DC blocking cap. I could use almost any buffer.
Are your proposing putting this before the cap? Is there an advantage?

He usually goes dc I think. Im sure he’ll be happy to answer with his opinions. He has had those things on the bench for long.
