RCA laydown head Nothing from 20 to 1200hz

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

WTF Not an amp issue, works on a 1d, Grampian, and tkv head. Embossed sin wave sweep from 20-20k, and head wouldn't play back anything below 1200 hz. Attached is a picture of the spectrograph captured from Audacity. The head is an RCA MI-11850-C. Any hints what's up with my head?
