Hello,
I have a very lightly used Sowter 1290 trannie that I bought for a MEQ-5 build that was pulled from service before the first build power up in favor of a last minute Traid HS-56 find.
The unit is fully tested and working, but the wires have been clipped and the case shows a couple of light scratches. The wires scan easily be extended - if need be.

$100 USD with free shipping from San Francisco CA. Sorry, no International shipping.

From Sowter's website...
1290 Teletronix LA-2A Original 15K/600 Line op.
Ratio 5:1. 15k/600 ohms output transformer for driving balanced line from ac coupled cathode follower or SRPP circuit. Total dc resistance ref secondary 31 ohms. Colour coded leads and threaded grommet mounting. Max output level +30 dBu. 30% Mumetal core for exceptional bandwidth and dynamic range. Similar to UTC A24 and Triad HS-50 (in overall 5:1 configuration) but with improved bandwidth. Suitable for Drip Electronics Opto 4 and 5 PCB. Also suitable for UE-100 Output.
This transformer is very similar to type 1010 and is essentially a size and cost reduced version achieved by using a smaller lamiination size and a smaller proportion of Mumetal laminations. The can size is also smaller and less expensive. The performance is unaffected except at very high level low frequencies where the THD measures somewhat higher.
