A pair of very sizable bi-filar wound audio output transformers with a 1:1 ratio. Decent transformers which would be ideal for signal level / line level balanced outputs in pro audio equipment etc. They can deal with very high line levels with low THD.
Measured at 20Hz each winding has an inductance (Ls) of just over 23 Henries & a DCR of just over 20 ohm. I have added some plots of them driven from a 10 ohm source and with either a 10K or 600 ohm load - as can be seen they have exceptional performance (which extends down to a few Hz!). The very slight upper resonant peak could be tamed with appropriate output network, although it’s so small it’s probably not worth the effort.
They measure approximately 68mm wide (excluding mounting lugs) by 45mm deep by 58mm high. One winding is the twisted white and yellow - the other winding is the twisted white and orange - the white being the start of each winding on both.
Not sure if these have been used or not, either way they are in very good condition. Any questions please ask. I have hundreds of audio transformers & related bits - please see my other listings.
