Early Freshman Masterpiece

[fsjonsey]

Hello everyone,
Last week, I picked up a 1924 Freshman Masterpiece For $15 at an a antique mall. The other day, I popped in a set of 01A's, connected a 6V 5AH SLA battery from an exit sign as an A battery, and used 10 9 volt batteries in series, tapped at 45V for the Amplifier and Detector B+. Plugged in my RCA 100a Speaker, connected a 100ft long wire antenna, and fired it up. No dice.

I finally had a chance to open it up tonight, only to discover that both of the audio interstage transformers were missing. I replaced them both using this cap/resistor mod:

Finally, I have audio, but it's extremely faint. Also, the only range on any of the three dials that will barely pick up a station is about 92-100 on the 0-100 scale tuning dials (all dials are set to the same position). Below 90 or over 100 and the set goes completely silent. Any tips on working with this dinosaur would be greatly appreciated. This is the first three-dial TRF set I've ever owned. The oldest set I've had any experience with prior to this is a Radiola 18.
