building another Tube mic

Let's say we're not going to invent the warm water and start with:

-decent capsules like the Oktava Mk-012 series
-the capsule can be connected to a new body using  the Oktava -10dB Pad
-EF86 or another decent tube
- a lundahl transformer like the LL1576
-the t.bone PSU Retro Tube II , you can buy it at:

Or is it better to buy the Oktava “mini tube"?
( would love to see the schematic)

Alternative :  Gefell  m92 with mv691 or692 Body.  A  6s6b Tube and a  Haufe t14/1  you should. Be able to get all that for 250€

Definately e.oelberg idea is more interesting, at least for me
Also you could use gefell transformer for tube circuit These trannies are ultra great.

Wonderful chunky thread on the 691! Looks nice and solid!!

I want a thread like that in my life.  8)
