As you've found - most of the changes are documented there - the reset switch is no longer the 2 part switch used by the original QL, but takes a standard footprint momentary switch with 6 pad layout.
Checking out what components left for my repro Tetroid Iss6 in service manual...
L3 & L5 have not reference at all on it.
Only in the Schema. Based on Schema:
L5 = 22uH
L3 = 22uH
But... no idea what other electrical or any other attb they should keep.
L5 needs to be a large 1 or 2 W inductor as it's in the 9v feed for the Microdrives and is there to prevent noise being passed through the supply. It should be rated for at least 1 Amp
L3 can be a lower power - 1/4 W inductor - it's used in the PAL video encoder chip circuit.

Both components should be axial types with leads.
Thank you
The share the same footprint so ... I will put same type, and at least 1W (perhaps 2W if it is not too big)
