With a tube amp you should always keep the speakers hooked up. You are correct, tube amps need a load or else they can be damaged!
amp blowing fuse
- Powered up my tube amp this a:m and almost immediately the fuse blew. It happened so quickly I don’t even think any voltage was reaching the tubes Put the fuse from the other mono in and got the same result. Going to buy some more fuses now and my question is could a bad power tube cause this? Or does it seem there’s some other internal issue ? The tubes are brand new so I don’t think that’s the case but I guess it’s always possible The amps have been in hibernation for almost two years
