Hello everyone, any help here would be greatly appreciated,

So today my new tubes arrived, M8161's, I did some research and found out about jumpers are needed to install these tubes, so i looked beneath my amp and saw the jumpers thinking they where already active... oppps, i know it was stupid but i have no idea about these things. I switched my amp on with the new tubes and nothing happened, so i quickly panicked replacing the tubes with stock LD MKIII tubes, and it still won't turn on! nothing happens when i turn my amp on? anyone know what happened? and if it easy to fix, or if my new tubes fried too? Thank you so much for your time!

-Mike

Hello its me again, i made a mistake,

I looked at the bottom of the amp and indeed what I thought was jumpers where not

so i turned the amp on with no jumpers for the M8161's!

Will you go on the Little Tube forum and leave a question there also? I am sure you will receive an answer on this matter!

I do not know enough about the jumpers to answer you!
