I ordered an ACM-900 - yes. I really have to wait to see it (and certainly to soak up the sage advice of the many, many folks here who will know better what to do than I will), but the transformers look like the ones I replaced to good effect in the last round of GB ribbons. Have to wait to see what specs the replacements should have. I'm liking the Edcors that I have, and they're inexpensive.

Don't stare at the eye.
Yeah, after he soaks it up, I'll ask him to dribble the wisdom down to me--then I'll panic and probably do nothing.
...must be strong...

The 1st transformer ought to be a real big ratio--something like 1:200. Otherwise it doesn't make any sense--the noise will be way up and tube work with way too low source impedance.
If somebody has the stock transformer and willing to send my way, I will be more than happy to measure it.

More on this one... The tube is a 6J1 (*not* a 6J1B, which has flying leads instead of pins). Recordinghacks has this page on them: http://recordinghacks.com/microphones/tag/6j1
The common old stock designations for this tube are EF95 (European?); 6AK5 (American commercial?); and 5654 (American military?)
The good news is that there are a bunch of them out there! - I picked up a handful this morning locally and tried them out. I've got an RCA in place now, and I hear a definite improvement over the stock tube. Less wooly - better highs, better lows.
As most of us probably know by now, the transformers are in little (mu-metal?) boxes -- I think I'm gonna wait to see what TnC come up with before I try anything crazy with them.

Don't mean to be a re-animator, but I pulled out my ACM-900 this weekend, and used it some, mostly with the ACMP-73 preamp w/o EQ. Nice!! I've started layering tracks of crappily performed vocals, and it's going well. I also gave it the torture-test - my toddler singing her repertoire of children's songs -- and again, it performed admirably.
When she was singing in the front, I thought I could stand in the back and sing/talk, but it was almost like the back was in a nearly-null spot -- not acting like a figure 8 - not sure what's going on there, because it doesn't make sense - I'll do some more research.
Mine is still stock, except for an RCA tube that I put in - details here ( https://homerecording.com/bbs/showthread.php?t=278255 ).
Anyone else using one of these?

I tried a vocal thru mine when I first got it and didn't like it at all. I did some hand claps thru it recently and they sounded good. I should try swapping out the tube. I think there are a few component swaps out there as well.

is out. Leave a message.
It's consistent across all the lollipop ribbons. I think it has to do with reflections off the grille and/or pole piece somehow causing the polar pattern in the near field to be wretchedly uneven.
It behaves like a cross between figure-8 and omni, with lots of odd phase cancellation off the back side. Very odd. Back off a couple of feet and it behaves exactly as you would expect.

I've got lots of NOS tubes for it, btw - PM me if you want one.I tried a vocal thru mine when I first got it and didn't like it at all. I did some hand claps thru it recently and they sounded good. I should try swapping out the tube. I think there are a few component swaps out there as well.

I'd like to try some different tubes in mine sometime. At the moment it sounds really crisp way more than any other ribbon I've used. I haven't used it a whole lot though....if I put up a ribbon it's usually either the ACM-3 (I've been getting good results w/ these) or a Fathead (which I'm just not that crazy about).

My 900 was really dead sounding. It reminded me of a very lo fi recording with almost no 8k or above. But the vocalist was very close to the ribbon... I'm looking to pick up a new tube for it if it will clean it up a bit. Send me a pm with a price and I'll let you know.

echh. I left mine on for a few days, and now it seems to have a raspy hiss. Looking into it. I PM'ed you Bobby. The tubes are price-less - seriously, I grabbed a few extra for other ACM-900 owners, and they were so cheap that it's not worth selling them - happy to send one your way.
