TAD1000 Blowing Fuse

No changes to the system. Just started out of the blue. Any ideas would be great on where I should start trouble shooting. Thanks.

I'm not familiar with that amp, but assume it has a solid state rectifier. Normal troubleshooting would start with the rectifier tube, then go to the power tubes. If you pull the power tubes and power on, and the fuse blows, it's time to take it to a tech. If not, try different power tubes.

Insert tubes one after another till the fuse blows.
