Transformer identification Parmeko gardners RCA ???

[gary o]

Got some audio transformers ...wondered what I can use them for

RCA MI 12399.......1:14 ratio 250 ptimary 50K secondary with CT ??

Parmeko Neptunes series has this printed on it 6000/1 100ohm ratio 1/25 ??

Gardners 7006 printed on side on top is hand painted AF matching GR118066 Pri 6.25/25K Sec 100K


Was wondering if I could use them in Microphone or mic pres or compressor type projects

Thanks for looking

Gary, the RCA may possibly work as a mic input for a valve preamp.

I don't quite understand the Parmeko's label.

The Gardners may be ok as a line input into a valve stage. I'm not sure what examples there are of this though.
