Hi, I’m working on a Matrix 6R with corrosion damage from some sticky liquid spilled through the top vents. Most everything is now working but one of the coils for the HFO’s is too far gone. Does anyone know of a replacement part that could work? The original variable inductor was a Sumida E648 as far as I can tell. Thanks.
have a look here. You will need to measure the inductors and find a replacement.

Do you have a picture of it so we know what we’re looking at?
Presuming you have the schematic already?
Are they the L1, L2, L3, 3-7uH ones on the schematic?
There are loads of types of variable inductors on Aliexpress if you struggle to find one locally.
