Northern Electric R14849AS and R14849E (like Western Electric 618A) SUT transformer for MC phono

[rafafredd]

I've acquired these transformers from a lot of a retired engineer, and I've made it into two SUT boxes a long time ago, but then I've moved to another home and never got these listed up.

Now, after some years, I've found these lying in one of my boxes of stuff, and I would like to have them sold, but I don't have a real ballpark about the price range on these.

Does anyone have a ballpark on how much these are worth nowadays?

From what I've seen online the R14849AS is 100% the same of a WE 618A but made by NE in Canada instead of USA, and could go for a thousand dollars or even more. Is that true?

Also, I've looked for info and it seems the E version could also be used as a MC stepu, wired 150:20k (1:12 turns ratio), so that's what I did. It can also be used as 600:20k (1:6 turns ratio) with the impedance switch.

The "AS" version is wired as 30/120 ohms primary with a switch for impedance and a ground lift control. The secondary is 55k just like the Western Electric WE 618A transformer.

The R14849E version is originally an output transformer, but also have the same permalloy core and mumetal shield, so I've just wired it as 150/600:20k so it works great as a SUT for your cartridge. Also have the impedance and the ground lift switches installed.

Anyway, this is what I have, but I'm not sure how much these are going for. Any ideas could help.

I want to sell them, so if anyone is interested or have some offers, just contact me.

I've been selling audio stuff online for quite some time, and you can check my accounts on Ebay, DIYAudio.com, Gearspace and GroupDIY, all with good feedback, so buy with confidence if you are interested in these. Just look for the screen name "rafafredd" and you will find refetence, feedback and happy buyers.

I've heard these transformers are becoming rarer and harder to come by each year.

Thank you on advance for any tips you might have!

PS.: if you look at the pictures, you can see that the pins from the octal base of the transformers have been removed, because some were loose. Then I've soldered silver/teflon wires directly in the contacts, so in fact it gives a better overall connection then the orinal octal pins, specially for very low output cartridges. Transformers are 100% tested and working great!
