Hi,
As I extended my microphone locker, I took an attempt on the ElaM251. I chose the T.Bone SCT800 donor body, as it is realtively easy and cheap to get in Europe and comes with the PSU.
As noted in other posts, tube microphones run on high and letal voltage. Even after switching them off they may hold these voltages in the capacitors for quite some time. Therefore only work on these projects if you know what you are doing and bear in mind that you should handle these things with the care and attention that they deserve!
In the link below you can find a building guide, the BOM for the PSU board and the microphone PCBs as well as a sound sample of female vocals (thanks a lot to Julia Wohlfahrt).

For the capsule I picked the Maiku K12 and the transformer is a 3u audio GZT-12 transfomer. The tube is a TAD 12AY7/6072A Gold (provided by Banzai music, order# SKU58307). The sound sample was recorded in cardioid pattern.
Here you can find some pictures:
Last but not least the project has been highly influenced and some solutions were simply copied from members of this forum (e.g. matador, khron, poctop, chunger, and others) - thanks for all of their posts, ideas and solutions that they have shared over the times.
Thanks again for all the nice hours I spent browsing through this forum,
all the best
