There is a second one available for the same price if you need a pair I can list it also or whatever. The primary is 20,000 ohms center tapped or 12,500 ohms center tapped or 5000-3125 ohms, the secondary is 500 ohms center tapped, 200 oms center tapped, or 333, 250, 125, or 50 ohms, 15mA DC  max., 2mA unbalanced max. 30dB hum bucking. The stated frequency responce 20-20,000 Hz at a max level of +18dBm.  This was owned by a retired Altec engineer friend of mine that used it for 600 ohm balanced XLR to RCA jack high impeadance matching, he would always tell me how great these transformers were for that application. After I got it I used it and its mate for high to low impeadance matching out of a CD player to a mixers XLR jacks. It checks good with a meter but as with all old stuff must be sold as-is. I have to get rid of my stuff because my new son (now 5 wow) and now we have a girl turned 2 are more important than piles of audio gear I may never use. My normal shipping is UPS ground. We combine shipping. This is just a hobby for me to get rid of my stuff so other shipping methods must be arranged prior to bidding on the item. I package overkill so the stuff should arrive ok. Please note shipping to the continental 48 states only unless arranged prior to bidding. If I agree to ship outside the US I require insurance and a trackable shipping method using the post office such as airmail parcel post. Thanks for looking and I try to describe this stuff the best I can. If you are not satisfied please let me know and we can work it out. Winning buyer please contact me as soon as possible so I know you want the item and I will pack it up to make room for more stuff. All my collection must go. Thank you. Place a Bid!
