possible help with magnetic tape head?

I have a magnetic tape head from a pre-disassembled tape player some one gave me. I took off the head and i'm trying to convert it to 1/8" to run through my pre-amp, so you can play loose peices of tape with your fingers. (I do know this has been done many times before)

this is the wiring on the device and I've tried with banana clips doing

black to ground, white to lead or red to lead and vice versa.

none of these work, I'm not sure what I can do to get it to work, does any one have experience in this type of stuff?

you mean add a connector straight on the end that goes into a pre-amp? i don't think there's enough gain to do it this way, would need another circuit to sort that i think, but that's a bit much effort:

how i'd go about doing what you want would be to get a whole new other cheapy tape player and cut and lengthen the wires from the tape head so you can stick it down externally and run the tape over by hand there. then just use the headphone/line out to get your signal. better if you can strip out or disable the motor to reduce noise but watch out for tricky tape players that do stuff like checking that the motor is turning/lid isn't open etc. etc.

as for the wiring it's probably different for everything but on the dismantled walkman i have in front of me here it's red right and white left with a common/ground/whatever alongside, i assume you have a play/record head if it has 4+ground. try doing it that way and see, a pre-amp might just allow you to hear something but i'm fairly sure the volume will be too low.

yeah Im just going to use some other tape heads I have to get tomorrow. I'm impatient and wanted to get these to work some how. >:U
