tube

Hello guys!
I'm from the small country of Bulgaria and I need help from experts like you with identifying 2 vintage tube microphones that I've acquired recently.
Bought them cheap for $13 each. I believe these are Tesla made since there was a 3rd different microphone in the lot and its box has the same ornaments and finish as the ones I am interested about. I've disassembled both and they both have 5703WA miniature tube inside.
I am attaching pictures below.
Thanks in advance!

Hey all!

I just finished up a fun little project of covering the theme song to the tv show "Drake and Josh". I feel pretty good about the mix but I keep hearing a tiny bit of too much tube saturation/distortion on the lead vox. It's funny because it only catches my ear sometimes, and after listening again I can't hear it when actively listening for it. All of my levels are good and have plenty of headroom. I do have a bit of rasp in my voice and i'm wondering if that's what i'm hearing.

Please tell me what you think!

I've recently been hearing whispers of this in the wind from some fellow engineers - but no one I've talked with has actually had a chance to use it... has anyone here had a chance to use this mic?

Priced at $499 ( new), the LA320 is a cardioid tube condenser, featuring both HPF and LPF; it comes with an external power supply.

Thoughts?

Can somebody tell me what they think of this mic? Groove Tubes GT 66?

Thanks

Hi,I'm new here,so first of all. .Hello.

Just been digging around some recordings I started a few years ago and I've found the most terrific sounding late sixties/70's Rolling Stones type guitar sound I've ever heard outside of "Honky Tonk Woman" and similar,it's that good (I wish everything else I'd recorded was),works in mix not just solo.

I got this by running a Les Paul copy through an ART MP tube preamp,the cheap basic one complete with Chinese valve into a 10 watt Crate practice amp,no valves and recorded on an SM 57 into a 16 bit Zoom MRS 1608.

Hello, I'm just getting into the very basics of recording and purchased myself an XM8500 mic. My uncle had a preamp/mixer that I was going to use, but for some reason the mic doesn't work with it. I've tried everything and decided that I would just get a new preamp instead. I'm on a very tight ~$50 budget and already have a UCA202 for an ADC (16 bit isn't a ton but I think it will work; ~600mV inputs), so I'm looking for a cheap preamp that would get me where I want, and the ART seems to be the only thing under $70 or so.

from what i gathered searching this site the tesla ec (forget model #) seems to be what i'm looking for, just wondering if anyone has some general suggestions/links as to the tonal tendencies of different preamp tubes.

Look at this gem!
