Here is the transformer and its mount-
ing screws 

HF-2500 Magnum 

Transformer Installation 

Procedure 

Position the transformer over the mounting holes 
in the chassis and insert the provided 1/4-20 
Phillips head screws through the transformer 
mounting tabs and into the threaded inserts in the 
chassis plate and tighten. 

Lift the transformer into amplifier chassis

 

Plug the first connector on the transformer into 
the mating one on the chassis wiring harness.  It 
is keyed so that it cannot be plugged in back-
wards.  Make sure that the connector halves are 
pressed together until the lock tabs snap in place.
