Hi,
I have a 5 watt valve head for my Guitar that I recently bought, and am saving up to buy a good speaker. For now, I want to try it out, but all I have is the 6 inch speaker from my old Laney solid state combo. I measured the resistance across the two terminals of the speaker, and it read 4.7 ohms. Is this ok to plug into the 4 ohm tap of my amp, or should I use the 8 ohm tap, or neither?
I know that its generally not a good idea to have a higher impedance speaker than the socket, and it might kill the OT, but seem as it is 0.7 volts, I have no idea.
Thanks in advance!
Billy 🙂

It will be fine, but 4.7 ohms resistance is about what we expect from an 8 ohm speaker. So it would be better to plug in to the 8 ohm tap.
(The nominal 8 ohms of a speaker is a 'reactive impedance' which includes the coil inductance etc. as well as the resistance.)

:Cop: Since this is guitar amplifier related this thread really belongs in the Instruments & Amps forum where I'll move it.
