HotSMD Audio Isolation Transformer, ED8-600Ω to 600Ω, 1:1, 6-Pin, 10.5 mm, 1250 V AC Withstand Voltage
A 600Ω-to-600Ω audio isolation transformer in a surface-mount package. The two windings are 1:1, so the device acts as an electrical isolation break in a line-level path rather than as a matching transformer: the voltage across it remains unchanged, only the ground connection between the two sides is removed. Six gull-wing leads, three per side, let it mount on the board like any other SMD part, which is why it sits alongside the through-hole parts it replaces.

ZXY-ED8-10 1:1 Audio Isolation Transformer, 600 Ohm to 400 Ohm Line Matching, ED8X10-2.0H Laminated Core, 14mm Package Gull-Wing Terminals
ZXY-ED8-10 is the product name, and ED8X10-2.0H is the model number: ED8X10 indicates the package size, measuring 0.555 inch × 0.313 inch × 0.197 inch; 2.0H indicates a minimum inductance of 2.0 henry. This device has no printed label. The only slight marking is on the bobbin between the core and the clip, which is too small to be discerned in photos and too dark to be photographed against the varnish background; the full model designation appears only in documentation.
