There is a Model 20 speaker being advertised on ePay right now as we speak. Seller is "oldtvsandtoys", 2 days left, no bidders yet, starting bid is about $20.00 Disclaimer: I do not know this eBay seller and have no financial gain from providing this info. I apologize to the Moderators if this post breaks any rules.
I am working on a Model 20 right now. The case is a basket case and I am still working on the chassis (Yep, the coils!!) I'm using a modern 8" 8 Ohm speaker, a 3K 10 watt resistor and 40 / 40 uF capacitors. Not original but works well before another RF Coil opened, but still receives my talking house transmitter from the detector grid. The modern speaker is low end but still sounds much better than an original condition Model 20 that I repaired. I may put in an Aux input and audio volume control between the detector and 1st AF to hear how good the Push Pull 71A Amplifier sounds. This radio is not good enough and complete enough for a restoration to original condition right now (Although the 3 24as and 27 are Philco branded globes. The 71As and 80 are RCA Globes. I got the chassis and case separately, the chassis without tubes.
