**BUG**
Concise problem statement:
Sim fails due to:
`Error: unknown subckt: xt1 xt1_1 0 0 volprobe1 mutual_inductors`
The problem is that the `Mutual_Inductors` subckt *does* exist in the EasyEDA spice model library:
`.SUBCKT Mutual_Inductors_%s n1 n2 n3 n4`
`*`
`* Updated to add Rdcpath1 - Rdcpath4 to `
`* provide DC paths to ground in case any `
`* winding is left floating by mistake.`

`L2 n4 NetR2_1 %s`
`Rs1 NetR1_1 n2 %s`

*************
The schematic has correctly called the `Mutual_Inductors` subckt from the EasyEDA spice model library because it is in the netlist!
The EasyEDA Source for the 'Mutual_Inductors' schematic symbol seems to be OK:
