Ok, I'm baffeld. I find no RFC before T2 in any version of minima I can find a schematic of. Near T3 in the detector there is a RFC however. For that choke the key feature is to have low loss core and self resonant frequency higher than 20mhz (IF frequency). That makes it a fairly non-critical part. SMT parts should work if they meet the above. For the breadboard I'm building I used 8 turns of #28 on a FT23-43 has I have a few. The value there is not critical as its reactance should be about 10X 50 ohms or 500ohms. 8 Turns on that core is about 1200ohms reactance with minimal capacitance.
