Scotty, I need more power!
I’m giving it all she’s got Captain.
“No worries.” thought Mr Emergency Preparedness, “I will just replace them with backup tubes.”
And I do carry backup tubes. Lots of them. Various models of 12AX7s, EL84s, 5Y3s. Somewhere over 40 tubes in the closet. There was only one 6V6. A purist will tell you that you should always replace power tubes in pairs. Matched. A purist will say a lot of things about tube amps. More than I thought was possible.
So why did I have only one 6V6 as backup?
Maybe it was when I changed the tubes out in my 1984 Fender Super Champ.
The Super Champ is a Paul Rivera designed practice amp that puts out a pretty impressive 18-watts. Mine is all original and in brand new condition. Some folks like to swap out the 10-inch speaker to get less of a midrange sound out of the amp. But miked on a stage, this little beauty can really crank.
The Super Champ is now without two 6V6 tubes.
I was able to get my Swart back up before the rehearsal by raiding the tubes from the Super Champ. I bought two more 6V6s locally and I will order a few more.
I did panic for a little while. I had not realized the full extent to which I had fine tuned my tone to the Swart amp.
Maybe I need a second Swart as backup?
