[HBR] 85Khz IF Transf.

[Tony]

Tnx for the info Darrell.

One other question comes to mind here in that the transformers I have are from an R23 and have tapped coils in the first and IF second cans.
Was wondering if it would be better to modify the connections or use the taps as they did in the R23.

Tnx and 73,

Tony
