What model L Tatro is this
Nothing printed anywhere. Big clips on the power leads suggests a battery radio or a really makeshift power supply.

There seems to be no rectifier and the tube filaments appear to be battery type (thus why I did not call them heaters) so I agree with your guess that it is a battery radio.
Do you have the Collectors guide to Antique Radios? If so look up the maker, look at the models that are battery sets and compare cabinet descriptions, then look up the riders (especially if there is more than 1 match) and see if the chassis matches the riders.

Those big battery clips suggest operation off a 6-volt storage battery. I'll bet the metal box contains a transformer and vibrator high voltage supply.

I have a Setchell Carlson tombstone, that I converted to AC operation. It was an interesting conversion. It uses the speaker field to drop the 6 volt source down to 2 volts for the tube filaments. That model is not covered in Riders. |

Was probably a farm radio. Back in the days where rural locations didn't have access to REA electricity or them there fancy shmancy tely-ma-fones.

Furnish the tube types, so a comparison can be made. |

Tubes are 1B5, 1A4, 1C6 and 1F4
Update: Model EN6-4 may be the winner. [image removed] Sent from my SAMSUNG-SGH-I337 using Tapatalk

Got everything recapped tonight. Hooked up a small 6V wall PS without tubes and heard the vibrator humming. It wasn't enough to light the tubes though. Would something like this power this radio?

It likely would have enough power, but SMPS tend to put out lots of RF noise that would jam reception. Personally I'd look for an old transformer type 6V battery charger and put 2-4 stages of RC and or LC low pass filters between it and the radio.

Kinda what I thought. I picked up an EICO 1064s and powered it up after all the caps were replaced. Good news is that she plays and has decent reception but the amplification is low. The speaker is a small replacement that was in the case when I got it so I need to figure out what the correct speaker would be. Also, the IF4 tests borderline on my Nat'l Lab tester. Also need to verify all the resistors.

You'd have to consult a tube manual to see what the plate load is needed for that particular tube. |

Works OK on my Coronado farm radio, that uses a 33 output tube. The radio originally used a magnetic high impedance speaker. |

I connected this to the coil/speaker on another battery radio and it sounded loud and proud. It was a 675 ohm coil I believe. I found a 400 ohm coil and used it with the little speaker and it improved the sound tremendously. Looking for a 5" speaker and 600-700 coil.
