DIY Tube Mic project

[Emmathom]

Some people just like the physical shape of the glass envelope of vacuum-tubes, along with the soft, warm glow that emanates from within them!!! What's there -- NOT -- to love about vacuum-tubes.....despite all of their inefficiencies???

Inefficiencies ??? could you be more precise please ?

Inefficiencies ??? could you be more precise please ?

It is about energy inefficiency, electrical yeld, high consumption, a lot of dissipated heat, heavy equipment, etc.

I understood what you said from the begining but I wanted you to be more clear...
BTW why write your arguments in bold ?
Your style is a bit agressive for me - my POV -

PS : if you don't like tubes that's your right, but don't disgust others. Thank you

[if you don't like tubes that's your right, but don't disgust others] -- YOU'VE GOT BOTH ME AND MY ATTITUDE ALL COMPLETELY WRONG, Buddy!!! -- >> I LOVE VACUUM-TUBES!!! << and actually prefer them to all of the new-fangled digital stuff!!! I've got vacuum-tubed audio amplifiers in my radio-production studio, some old vacuum-tube preamps and I've even still got an old vacuum-tube AM-transmitter that some guy had built for me back in the late-60's!!! So.....calm down, OK???

@MidnightArrakis
Your description of valves/tubes strangely reminds me of my woman:
“Some people just like the physical shape “
Even her inner being: “along with the soft, warm glow that emanates from within “
Absolutely right: “What's there -- NOT -- to love about her”

Yes I’m sure there’s better out there “....despite all of her inefficiencies???”
(She allways gets lost even with Google maps).

But just like a good Fender Twin or a Marshall JCM 900... there’s something about Her, that I cannot clearly identify or quantify and I just love it. I rather stick with Her (valves) I would miss Her if She was not around.

PS: Gentlemen take it easy, Text messages, e-mails and GDIY posts DO NOT transmit accurately our real human emotions & personalities. Don’t get too offended please.

Hi guys
I will come back in a while with modifications on these 6AK5 mics (I'm building a second one for fun) : capsule, capacitor, output transformer... and also picts of the metal work process to fit the t.bone SC440 USB (body donor) with XLR connector and some more infos...

Pict of the PSU : on the back pannel is the main switch (and heater on). On the front pannel the led indicates that main power (and heater) is ON and the led-lighted-switch activates HT (I know that the cooling holes [for LM137 heater heatsink] on the top are not "nice" > will do better for the second one). The enclosure is almosy full...

See ya
