My amp just died, and some ohm questions

Post by sp3k »

My amp just died yesterday. I plugged it in and no sound comes out. I've tryed other cabs and cables and all that stuff, it's the amp...

The valves all light up. I poked them and no sound came out. Any advice? should i just take it to a tech? tha last time i did that the fucker made me pay almost 80 euros for a bunch of stuff i didn't want...

The amp is a orange dual terror btw.

Also, the amp has a 8 ohm and a 16 ohm out, i can't plug it to a 4ohm cab right? and can i plug a 4ohm out amp to a 8ohm cab?

No can't plug it into a 4ohm cab.
You could plug a 4ohm out into an 8ohm cab and it would be "ok", but it does totally depend on the amp and the output transformer.

I'd just take it to a tech. Assuming that you've checked that the volume isn't at zero ;)

its a bassman 100 that the guys in my new "studio" have. It sounds so good with the 2x15 speakers, but i would like to try it on my 2x12 cab.

Should be fine, old Fenders are pretty good at mismatches. There's some really good info on OSG in the technical amps section, in the FAQ or something.

Thanks Thom.

I bought new valves, and it still doesn't work, so a tech has the amp now.

please post more info, maybe a schematic if you can find one, otherwise here is a good amp troubleshooting list that can help narrow down issues:

The tech fixed it in a few minutes. Some really thin wire couldn't take the bass power of the dwarfcraft robot devil, so it got disconnected. He soldered a new better one and had to change to fuses.

the WORST thing that could have happend is that the output transformer is blown, what would cost 100 new. so nothing that couldnt be fixed..
