MY BUSINESS PROPOSITION

Musical Power Supplies, Inc. was set-up to fund a hobby only...not to make a living.  We will design and procure batches of custom designed magnetics as fast as we can sell them or design new ones that folks like you want. 

If you are buying OT's for a Stereo application please contact me & I can attempt to match the Inductance of pairs. Normal inductance tols in manufacture will be +/-10%.
