	I would be very grateful if you tell me any common device that has 4.5-MHz 1F-can-style RF transformer. I'm seeking for it. Please help me.

	If you're looking for a specific IF strip then tell us what it is... I have designed IF strips for spectrum analysers and 4.5 MHz is fairly simple BUT it does depend on the bandwidth and shape of the pass band curve to determine exactly what the design criteria are...

	I haven't seen these in catalogs for some time. Locate an old tube-type TV where there should be two or more that could be removed.
