Well, maybe you can measure the primary size and report back? I head always hard they were 1 5/8ths primaries, which IMO is a bit small.

The PPE's and momentums are (at least) 1 3/4. I know that seems like a small difference, but small changes like that make big differences.

That and I'm not crazy about the FI's collector design.
