The build involves taking a cheap Chinese condenser and stripping it of
everything except the case and the capsule: All components were
stripped off of the PCB and the 3-prong XLR was removed, leaving
basically a hollow tube with a mic capsule on the end. A 5-pin XLR is
retrofitted into the end of the capsule and wired up directly up to the tube leads. The original chassis ground of the mic is wired to pin 3 as per the schematic.

| Not my prettiest work, but functional. |
By the way, check out these NOS tubes I scored on Evilbay:

| RCA 5840 |
I used some perfboard to build the boards for the power supply. These are wired up just like the schematic. Lots of good advice on
the tape op message board and
groupdiy.com .
This guy did this same build, but has quite a bit more skill than me.
