Listed with kind permission from Kevin are my pair of LL1660S/14mA.These are the 'S' version which have the faraday shielding and better balance when used as SE to PP phase inverting transformers. In this configuration they are good for 1:0.9+0.9, also ~2:1+1 for lower drive impedance.
These are the same transformers that some (search) rate higher than the Tango's for line-out at 4.5:1.
I have found the 14mA rating to be a useful medium between the standard 10mA and 18mA builds. Works out for ~12mA is 4.5:1 SE or, ~25mA as SE to PP allowing for some beefier driver tube options (EL34, 6BQ5, 6V6 etc).
I was using them with 71A at ~20mA. Max current or max voltage swing never exceeded, these are a very well looked after pair and will suit the most discerning buyer. Asking price is $200 for the pair.
Cost price air postage world wide, I pack items better than most. Your satisfaction is guaranteed. Please email with any questions.
I have quite a few tubes listed at the asylum trader that would work well with these. For example triode connected E280F, or ECC99 as a driver to some nice vintage 2A3 in PP/differential, etc.
Thanks for looking, Shane
