If you need parts quickly, our EBay Store will give you access to most current inventory and shipping will generally be within 1 business day.

***NOTE- We don't normally prefer to sell and list Custom Part Builds using EBay, but in today's challenging International business environment EBay Global Shipping will offer a reasonable global forwarding logistics option outside the USA- much better than handing the parts to USPS and hoping all of the offshore import processes work well.  The new practice available will be to set up EBay custom listings as MAKE-AN-OFFER Store listings with a crazy price.  The requestor can make an acceptable offer we've agreed to <in advance> using email or ebay messages.  EBay fees will add a bit to this method- but EBay Store runs a nice international  tax engine with VAT and Customs brokers and beats USPS Priority Mail pricing.   In this case the fees seem worthwhile.***

Stock and Make to Order Items can also be purchased directly using PayPal. 

It is now possible to arrange local pickup in the Nashville TN area.  We can work with Venmo or PayPal.

Ordering by EBay is convenient, but if you need a more precise quote or are ordering several parts it can be simpler to contact us directly by E-Mail.  We can send a direct invoice to your PayPal address and offer quantity discounts.  Often the best shipping rates and lowest total costs are obtained this way.

  • Products you need by Part and Quantity

Shipping Estimates USPS Site

SHIPPING:  

EBay listings are back to USPS as the 1st choice. Their service is less expensive and has been improving.  USPS Flat Rate packages are a great option if you need several parts. If you still FEDEX  will remain as a more trackable option.  
LOCAL pickup is an option if you live near Zip Code 38401 in Tennessee

Domestic US shipment is by USPS Ground Advantage , FDX, or UPS
Canada shipment is by USPS Priority Flat Rate or EBay Global ShippingWorldwide shipment is by USPS Priority Flat Rate

 INT'L Shipping is generally by USPS Priority Mail.  The fall-back option is to conduct non-USA sales using EBay Global Shipping.  Forwarding and Tax/Duty/VAT control seems better there.  International Custom part orders on EBay require use of MAKE-AN-OFFER type listings so we can direct the sale to YOUR EBay user without "poaching".  Contact us by email or on EBay to set up a custom part purchase using EBay.

International Shipping Notes-  from  postcal.ups.com

  • Upon Invoicing we will provide a firm shipping cost upon taking your order and before payment
  • USPS Priority Mail is typically a 6-10 business day shipping route with some limited tracking.
  • Priority Padded envelope tracking just indicates data entry.  A proper shipping box is used inside the padded envelope
  • A phone number for Customs Contact is recommended on the Int'l shipment
  • Finished Audio Transformers from Musical Power Supplies will normally be exported using HTS Code 8504.31.40 Having a power handling capacity less than 1 kVA
