Hi there, first time poster here! My mother-in-law offered me this amp that was her grandmothers that she had gotten refurbished, and I was looking for info on it online to use it best and keep it in good condition, but I can't find anything from a few google searches, and the label on the back is too faded to make out. She said it's from around WW1 era if that helps. Still works great! Though I noticed after only a few minutes of playing the top piece got a little hot. Thanks for the help!
