Welcome to Musical Power Supplies, Inc.

Musical Power Supplies, Inc. has been providing audio transformers for Vacuum Tube Guitar and Audio applications since 2006.  The designs we create and sell are original and utilize the finest audio grade laminations and proven manufacturing techniques.  New designs typically evolve from low volume manufacturing in our own US shop, to volume manufacturing sites as demand and volume grows.  Most new product is now being built in the USA or Mexico.  A core group of the most popular offerings are typically available from stock at the EBay Store, or reach out for a PayPal Invoice via email to save a few bucks in fees.


MPS EBay Store

When you are ready to order, Musical Power Supplies keeps an available inventory of Stock Items on our EBay store which is the best indicator if a prioduct is available from stock.  Additional discounts are available for single order or volume purchases via PayPal invoice  if you contact MPS directly.  All payments are processed by PayPal unless special arrangements are made by email. Custom builds are also possible and built per quote.
