I'm wondering if anyone has a x-reference for TMC pn's. My SBE manual also has the Fed. Stock Nr's for each part. Anyway to x-ref those to MFg'rs? Like for transformers? My defective transformers have "TMC" stamped on them. Tony, do you have any info as to where these may have come from? I thought maybe HAmmond but they don't have what i need, at least not listed on the web site. Larry W0OGH
