APS audio transformers

You send us your complete unit and we will install the Vocm mod and your new transformers if purchased.

You must pay for return shipping.  We will contact you for return shipping cost.

This price includes the standard Vocm caps.

This is a Level 1 upgrade.  The least expensive. We use standard Vocm caps and do not change out the 1% thick film resistors.

For a Level 2 upgrade see our Signature Series.

For a Level 3 upgrade add the PLUS upgrade for the instalation of our internal analog power supply.  This is the best and most expensive however we feel it's worth every penny.
