I have a Superior Broadcast Products exciter with no model number listed on it. Behind the Superior label, it says TF (m) 30. Any idea who made this for them? I contacted Superior for a schematic and haven't heard anything back. Does aybody out there have a schematic or manual I could copy? I have checked the web for some of the foreign mfg's like RVR and Elenos to no avail. I'd like to get this thing working.
