In place of a high impedance horn speaker, I would like to use the output transformer and speaker from a battery radio that used a 3V4 as an output tube. Assuming the speaker is 3 or 4 ohms, is this too high an impedance for such an old tube tube as an 01A?
The plate voltage on the 01A would likely be around 90 to 135 depending on the power supply I use.
