25EC58 is the last year flat SS chassis. The best ever built. They were replaced by the 25EC45 upright CC2 sets mid model year. Never known for buzz like
the all tube sets. Audio basically same as hybrid. Normal no equipment
alignment is.
1) set RF & IF AGC controls. ( some chassis only have one )
2) Adjust detector coil for minimum / slowest buzz.
3) Adjust SIF coil for minimum hiss.
