I've got an AD30 Combo amp that I've owned for a year now. It worked great up until yesterday when I suddenly had no audible sound. Upon further reading and investigation, it appears that the HT Fuse is blown. I know this is a 500mA fuse, but is it Slo Blow? 250V?
Would something like this do the trick?

AD30 Blown HT Fuse - What are the specs?

Re: AD30 Blown HT Fuse - What are the specs?
Also, should I go ahead and get a new rectifier and/or power tubes or is it possible that simply changing the fuse will suffice?
Re: AD30 Blown HT Fuse - What are the specs?
Usually the fuse blows because there's an issue. I use fast blow.
Re: AD30 Blown HT Fuse - What are the specs?
OK thanks, I'll try a tube swap and a new recto.
Is 250V correct?

Depends on where you live and what the voltage is.

HT fuse value doesn't change with different mains voltages, only the mains fuse.
But yeah, as Billy says it is always nice / handy to know your location!

OK, I will update it. I'm in the US.
So would that be 250V or another value?

Yeah, they should be slow blow.Sooner wrote: ↑Sat May 13, 2017 4:31 pmThe manual calls for a slow blo: https://ln-media.orangeamps.com/wp-cont ... Manual.pdf
If you use fast blow, they are likely to keep on blowing as the current surge upon powering up might overwhelm the fuse.
If your fuse has blown, it's likely caused by an issue somewhere, usually power valve related.

Re: AD30 Blown HT Fuse - What are the specs?
Yeah, it's the other way around. I use fast blow on the mains. Slow blow on the HT. T for time delay. T500mA.Sooner wrote: ↑Sat May 13, 2017 4:31 pmThe manual calls for a slow blo: https://ln-media.orangeamps.com/wp-cont ... Manual.pdf
