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. 

There's a really sophisticated inventory control system here....we're going to order another 500 part load when the 1st load is half shipped. If you  have a stellar idea for what ought to be in that next load drop an email to us, or better yet...order a custom transformer to prove it!  Depending on cores and bobbins we can get about 5 variations into a single lot. 

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%.
