3500 Ohm Single ended 10W Output transformer (KT88 or similar)

Description

A high quality 10W Single ended output transformer. May be used in any single ended design with a valve having an output impedance of 3500 Ohms, such as a KT88.

Primary

90mA DC current
Multi section winding, for reduced leakage inductance.

Inductance

Inductance 24H at 25Hz.
Leakage inductance 15mH

Bandwidth

Wide bandwidth, 20-30KHz. (-1dB)

Secondary

Output impedance 4,8 and 16 Ohms.

Steel

High quality Grain Orientated M6 0.35mm.
Hand laminated for the best stacking factor, and accuracy.

Winding wire

Double coated Grade 2 enamelled copper wire.
Wound using CNC winders for highly accurate wire placement and turns count.
Layer wound for excellent wind consistency and alignment resulting in reduced leakage inductance.

Connecting wire – stand up only

High quality PVC 600V
Primary : 24AWG UL1015
Secondary : 20 AWG UL1015

Mounting

Available in Frame, Drop through or stand up versions.
