Power Amplification And The 245 Tube - Radio News 1929
I've been doing my homework researching the old triodes when I found this old article. It is just two pages but I also noticed the magazine was packed with info on the 245 and some on the 250. I included a few ads from the magazine as well.
I really like the simple utilitarian look of this amp. 225 245 and 280 tubes.
