IMPORTANT NOTE: 28th September 2018
Amp Maker is currently closed for a year as I take a sabbatical. It will re-open in Autumn 2019. During this time, you cannot place orders, nor will I be available to answer email enquiries or offer technical support. The construction manuals and amp building info will remain available.

While Amp Maker is closed some of my transformers will be available to buy directly from the manufacturer: Primary Windings. The first is the 0-190-275V 20W mains transformer, and the next is the 15W single-ended output transformer. Others - including 5W and 18W output transformers - will follow.
