Hello,
I have been researching tube preamps, I am looking for 4 channels of tube preamps for use with a stereo pair of Pearl Elm As, (dual output mics).
I record folk music, and would use them for minimalist recording and main pairs. I am really inspired by Kavi Alexander's recordings with rectangular diaphragm condensers into the EAR 824 tube preamp into tape.
So sound wise, I am looking for a sound that is clear, open, but not harsh at all. Every time I have done listening tests, I land on tube preamps being the most pleasant to listen to.
But I am also looking for things found in tube amps made to be more linear/ "transparent" eg DW Fearn, Knif Audio, EAR, etc. Low noise, high gain, lower distortion, not purposefully creating distortion....
The mics I'm using specify 1k+ input impedance is ideal, so that would be good.
I have really liked the sound of Tube Tech pm1a when I have heard them, and ideally I would use something like 4 channels of those, because they are modular, I was also looking at the builds of Gyraf GIX 51X.
Anything else is getting to be bigger than desirable for my rather mobile purposes. But Pm1a are out of production, and I keep reading about low end rolloff in the GIX 51X, ideally I would have a flatter response.
Has anyone copied the PM1a, as it is no longer in production? They seem almost impossible to find used.
I almost bought the Sebatron VMP Quad Plus recently, but I think it may not be linear enough at higher gains, although I think it is well built, and It is still in the running.
I would be interested in getting a quote from a good builder to make something like the pm1a if possible, or something like the GIX 51X if there was a solve for the low end rolloff issue. That is for another post, right now I'm just trying to figure out what's possible.
So basically TLDR,
-looking for 4 channels of modular tube preamps.
-At least 60 db gain
-Relatively flat response.
-Linear at higher gains
-Low distortion for a tube amp
-1k+ input impedance
-Low noise (for tube)
-Maybe something like a 2 tube stage design with step up input transformer, 20db pad, lundahl, cinemag, jensen? transformers...
-2 rack unit space or less.
I am not experienced enough to build tube equipment myself, so I am just asking to see if there is a diy design out there that I could hire someone to build for me, OR if there is someone who is building something like this who I could purchase from.
Thanks in advance!
