OT15SE (USA) SE Output Xfmr 15VA @75mAdc - 5K to 4/8/16ohm - full covers

Description

OT15SE-5K
USA built version of Single Ended output transformer installed in HC100 covers
This is a new
15VA
Single-Ended Tube Output transformer for tube audio circuit applications (50Hz to 20KHz). This version of the transformer is built in USA to an MPS custom design specs & is suitable for many 10 to 15VA Single-Ended tube amp circuits looking for a solid USA built output transformer at a reasonable price.  We are using audio grade 29M6 laminations in a 1.25" oversized stack in an E-I 100 gapped core structure with bobbin wound construction.  It's an interleaved winding with 5K Ohm input impedances and three output impedances. It's surface mounts by a 4-hole pattern at 2.5in x 1.875in
This is ideally suited to SE circuits looking for up to 75mADC current handling
