Control reactive load reflection

[Bob Callum]

I have a non-conventional IF load which tends to reflect back to the
signal source rather than load up and radiate. I understand that to
minimize this it needs to float at a potential halfway between the
positive rail and ground.

But how is this accomplished in practice when it is being driven by:

1. A transformer secondary without ground reference?

2. A monolithic amp, SE or P/P, where the resistive path to the
positive rail cannot be easily determined?

Thank you for any insight along these lines.

Best regards,

Bob Callum

Do you have a schematic?
