OT20SE  USA built version installed in HC100 covers- fully shielded--  Back In Stock

This is a new 20VA Single-Ended Tube Output transformer for tube guitar circuit applications (50Hz to 15KHz) using large bottle power tubes such as 6L6, EL34, KT66, KT77, KT88 or 6v6 SE-Pairs. This version of the transformer is built to an MPS custom design spec & is suitable for many 12 to 20VA Single-Ended guitar amp circuits looking for a solid USA built output transformer at a reasonable price.  We are using audio grade 29M6 laminations in a 1.125" oversized stack in an E-I 100 gapped core structure with bobbin wound construction.  It's an interleaved winding with 2K3/3K Ohm input impedances and three output impedences. It's surface mounts by a 4-hole pattern at 2.5in x 1.75in

This is ideally suited to SE circuits looking for up to 90mADC current handling
