RCA MI-12241

So I just got a pair of RCA MI-12241 tube pres. Does anyone have any info, work experience, comments about this pre?

My own limited experience with them is this: I listened to it, I recorded a female vox through a ribbon and I liked how it sounded. I did a comparison to my API 512c that she sang through as well, the tube brought a cool quality out in her voice. Overall it's a pretty cool sounding pre I think, a little noisey (tube hiss-ness). I guess I could post the mp3s if anyone's interested.

Anyone else used these or BA-2As, etc? Besides vox, what else have you used them with?

Yes, I have a pair of those, haven't used them in a while, but used to all the time. I used them on electric guitar amps with a BK5 ribbon mics and shure dynamic mics. Vocals once in a while with condenser mics. Room mics on drum kits.

Powered with general radio tube regulated power supply. I also have the docs on them, to me they are just a nice sounding tube preamp. I think if you put 1620's or 21's (I don't remember what mil. tube it is!) instead of the 6J7's you get slightly lower noise. Hope this helps, Enjoy! PH

cool man, thanks. If anyone has info on swapping the tubes out for lower noise, that would be great.

so i guess it begs the question: If I'm liking the RCA tube, any other suggestions for old tube vibeness?

Besides an Avalon 737...

I'm totally kidding.

RCA MI-12241 preamp: kind of like a BA-2A with EQ addition

Also: if you go after lower noise tubes, there's little point in changing both, the 1st tube is going to be 95% or more of any perceived noise floor, the later stage simply amplifies the noise of the 1st. As rare and expensive as tubes are, and will increasingly be, I'd never indiscriminately stick 'low noise' tubes in every stage unless it's proven to contribute. Save'em for later replacement use!
