Kevin:
I think you might be right on the money for the one "volume control" because it is a coil that moves with the knob and depending on how the coil is positioned it makes the selectivity of the radio better or worse (better or worse separation between stations on the dial and also makes the overall reception better or worse depending on the position of the coil) and the second "volume control" which is the one that is actually a rheostat type control is the actual volume control because the overall volume of the set is made louder or quieter when that knob is turned. Titan1a: This radio I think is on par with Grebe as far as being a great DX'ng TRF set because as I said previously this radio was picking up stations loud and clear from as far away 300+ miles away or more, and this radio is still using the original bypass caps for the RF cans! Also I got my replacement speaker in for this radio's speaker cabinet which was an American Bosch Model 612 8" Dynamic Speaker just like what was in there originally so right now I'm working on repairing the blown out wood around the original screw holes that were used to hold the original speaker in place when the speaker was made back in 1927, and I'm making the repairs with Elmer's Stainable/Paintable and Sandable Wood Filler that also resists shrinking and cracking. Once I'm done repairing the damage I'll re-drill the holes back where they were originally and install the speaker and put it back together and wire up the speaker and test out the radio with the newly repaired speaker and see how it sounds and works.

It is finished! I have uploaded a video showing the after results of the restoration including what it sounds like with the speaker repaired (I actually had to repair the replacement speaker because apparently the speaker I got off ebay even had some damage to it (fairly minor damage compared to the original).
Enjoy! Pictures below showing what the radio looks like. YouTube Video Link Below: https://www.youtube.com/watch?v=P-1rXkXH_IY |

You did real good, it sounds very nice for a radio from that period. Now if you only had an outdoor antenna away from buildings with a shielded lead-in connected to a good ground, you could lose a lot of that buzz riding on the rf. With an indoor antenna you're actually picking up a lot of your signal that's being re-radiated from your AC wiring. In other words your houses AC wiring acts like a long wire antenna, but it's also got all the noise on it.

Understandable. Sometimes just getting the radio connected to a good earth ground can help, or even a separate long wire connected to the antenna ground can act as a counterpoise and cancel out some of that noise. Often it takes a lot of experimenting to find the best solution.

You did the best you could. To cut through the "crud" I use a very expensive amplified loop antenna. Listening to WSM as I type.

I was able to pick up WSM just fine on my radio with just a long wire antenna at 10 o'clock at night, I was also able to pick up the Oldies station out of Toronto, Ontario, Canada just fine on my radio as well on my radio at 10 o'clock at night one night with just a longwire antenna.

Excellent! Maybe I need to get one of these.

Yes, this radio actually has really good sound for its age and also it has great DX'ing abilities for a TRF set.

I know I'm late to the party here, but I own two of these. Mine are Model 2's, which are the same radio but in a green metal case. $75 is a good price; I paid about $100 each for mine.
On a whim I powered up the nicer of the two and was surprised to find it still worked! It's encouraging to hear it'll be a decent performer after restoration. I'm not a big fan of 1920s sets, but the Art Deco styling of these won me over. |

One question Tim, did your radio when you powered it up make a high pitched whistling noise out of the speaker while it was warming up? The reason I ask is because my radio when its first powered on and while its warming up makes a high pitched whistling noise out of the speaker before finally putting out an audio signal.

No. 43 the .002 MFD Cap is a mica cap so I didn't even bother with that cap. |

The whistling noise it makes when it first powers on isn't that annoying , because it does go away once the radio is warmed up, it doesn't really bother me that much it was more of a curiosity than anything. |
