Mic is finished and sounds fantastic...quiet and smooth. I ended up with a clarity caps coupling cap but I would like to play around with this. I am thinking of trying a PIO but it’s not easy to find one that fits. I ordered a couple of nos Cornell-D 1uf 200v that looks like it will fit...or I could go 0.47uf and use a k42. Anyone tried a PIO in that position? Any suggestions? Thanks in advance.

give a chance to NOS Soviet caps if they can fit inside

Hey Moby, thanks. I have a k42 0.47uf that fits. Do you like those or should I try a k40 instead? I think the 42’s are not as good as k40s but I could be wrong.

I like them both But you can always compare them. Matter of taste IMO

Sellers report good measurements as far as Vloss and esr. Hopefully they will be ok.

^Good to hear. Smart to go with tested caps. I have a decent stash of old NOS caps and it's ghastly to see how many of them test. Makes you realize why a lot of the audio vets are cynical about people using old caps.

I'm not into going overboard with exotic caps because that market is saturated with audiophollery but rolling caps in the M49 output was a real eye-opener for me. I am cautious to recommend thsi since it might not fit but check the physical measurements on the Mundorf EVO Oil (just oil, not the up-charged variants).

Also, good to hear about the tube!

Yes, I have had a few that I ended up throwing out but it seems that some of them have a few good years left. Trial and error I guess. I’ll take a look at the mundorf. Thank you so much.

So I tried one of the nos caps I got on the output. A Cornell dubilier 1uf 200v. I believe it is paper in wax but I could be wrong. Vloss and esr is really low.
Very different sound than the claritycaps I had there before. Less direct with softer/rounder highs and a general sense of roundness. It feels darker, more relaxed and “3D”...more natural and real but pleasant at the same time...This sense of “realness” might be, although contradictory, due to less detail and maybe more harmonic distortion that gives the impression of distance and space.
I’ll probably have to break it in a lot more so we will see...
Next will be a sprague metalized paper.

So just to make sure about setting the bias...
At b+118 I found the most “pleasant “ results are at:
A 43v
K 1.5v
H+ 6.3v

Does that sound right? Or am I out of spec? Thanks
