1:5 mic pre input transformers
« on: March 24, 2020, 09:50:18 PM »
Okay guys. I'm really liking the sound of the Cinemag 1:5 mic pre input transformer on my tube preamp. It seems to be middle of the road in terms of hi-fi with a hint of coloration.

Just out of curiosity, do you all have any other 1:5 recommendations? For example, going in both directions toward either neutral or colored. It would be nice to have a couple options for either super-fast transients versus big, fat vintage.

Anything that's off the beaten path and lesser known? Would need to be modern production and available.

Very simple dicrete mic pre, low noise, beautifully coloured sound!
(It´s not a fuzz box, you can make clean recordings with it too)

Jensen makes the JT-13k7-A. They also make a 1:4.8 input called JT-13k6-c.

Edcor makes a 1:5. No can on that one. You’d have to shield it yourself.

Sowter has one or two as well, One is a 1+1:5 (9045).

OEP may have one, Never bought any of their stuff.

As far as modern production, “off the beaten path”, I got nothin.

Whether you think you can or you think you can't, you're probably right.

I have been using Sennheiser TM003 transformers with great success in the past. (1:2.5 or 1:5)
There is a solution for every problem!

There's also Lundahl.  Having said that, your CMMI-5C is a nice choice.

Here's a different one for you, Dan. Check out the post in Magnetics about the A-10 clone from Crimson. They can customize a 1:5 based on the A-10 design for about $75 in singles. Probably cheaper in quantity.

You could also check out their standard input. I think 1:10 and 1:8 are stock options, but I'm betting 1:5 would be the same price.

Just a thought

That does seem very interesting. Thanks for the lead!
