ZXY-ED8-10 1:1 Audio Isolation Transformer, 600 Ohm to 400 Ohm Line Matching, ED8X10-2.0H Laminated Core, Gull-Wing Terminals in a 14 mm Package
ZXY-ED8-10 is the product name and ED8X10-2.0H is the type: ED8X10 for the package, which measures 0.555 in by 0.313 in by 0.197 in, and 2.0H for the 2.0 henry minimum inductance. The part carries no printed label. What little marking there is sits on the bobbin between the core and the clamp, where it is too small to read in the photographs and too dark to photograph against the varnish; the only place the type appears in full is on the documents.

ZXY-EI25 Flying Lead Audio Isolation Transformer, 1:4 Turns Ratio, 50 Hz-20 kHz, EI25 Laminated Core
ZXY-EI25, a flying-lead audio isolation transformer built on an EI25 laminated core. Its two windings are isolated and wound to a 1:4 turns ratio. At 1 kHz and 0.3 V the primary measures 56 mH min and the secondary 800 mH min; DC resistance at 25 °C is 1.6 Ω on the primary and 17 Ω on the secondary, ±15 %. The part covers 50 Hz to 20 kHz and is designed for low distortion across that band, which is why it is described as both a voice and a data coupling transformer.

ZXY EI28-600:600 Audio Isolation Transformer - Permalloy Core 600 Ohm to 600 Ohm 1:1 Turns Ratio Audio Isolation Transformer for PCB Mounting
The ZXY EI28-600:600 is a 1:1 audio isolation transformer built on a high-permeability permalloy laminated core. It couples a balanced signal from primary to secondary at matched 600 Ω impedance and transfers audio from 20 Hz to 20 kHz without changing signal level, while galvanically separating the two windings so that ground loops, DC offset and common-mode noise never reach the downstream stage.
