Here´s my next little thing for you
B2Pro builders:
How to create a nice housing/bottom for the transformerThe B2Pro is a transformerless microphone.So it has nothing but a gap on it´s bottom end.
I thought a bit about how to securely mount my T13 in my build.
I have read people tried to do that with unbelievable techniques like cable straps or even let them wiggle around inside.This can cause shorts on the xlr connections and therefore is an absolute "NO-GO"(...I wanted to avoid the word "B**LS**T"....).
After some investigation of my cellar storage I found some old and broken kitchen chairs like this:
The construction is from chromium plated steel at a diameter of 28mm.Cool!
So I cut off a piece of 35mm length and inserted it to the bottom part where the xlr is seated.
Like this:
I put on some shrink tube over the blank solder joints prior to that.
For putting it in I used a 2 component glue-this construction withstands even a tank attack.
Next step was to cut some stripes of rubber foam and carefully insert the transformer.
Like this:
Once fully seated slide back the pcb assembly so it sits flush to the bottom tube.Tighten the screws.Now you have no more moving parts-prominsed!And here´s the spot where you can apply your AMI sticker
After all wires soldered it should look kinda this:
Done!
Have fun,
Udo.
P.S.:I calulated that I can build around 700+ bottom tubes from my leftover broken chairs,not bad.....
