Pair of General Precision Stepup Transformer MC MM MIC Input Phono Stancor Triad

Description

Up for sale is one pair of Pair of General Precision Stepup Transformer MC MM MIC Input Phono as seen in the pictures. I think they are possible made by Stancor or Triad back in the days.
They are tested using signal generator and oscilloscope from 20Hz-20KHz. I don't use ohmmeter or digital multi-meter to measure the DC resistance on the coils since the DC current from ohmmeter could temporarily magnetize the transformer core and can arguably effect the sound of these input transformers. Of course, you should not use ohmmeter on them as any knowledge T/T guy would NOT too.
Primary side has 100ohm impedance and secondary side has 12Kohm impedance for about a stepup ratio of 10.
They both looks very nice cosmetic condition with only minor paint losses. They are about the same size as the Triad A-J series transformers.
Return is NOT Accepted Due to the nature of the Vintage Item.
I only sell the good parts and want to make sure you get the good parts.
They will be packed well for safe shipping.
I will ship them Internationally with USPS Priority Mail Insured.
Please ask any questions you have before purchasing them! Happy Listening!
