Blues Jr. / Pro Jr. JJ Tube Upgrade Kit (2x EL84, 3x 12AX7)

Q: Will this set work in a vox ac15?

If your amp requires 3x12AX7's and 2x EL84's then this set will work perfectly.

Q: Who or what is tesla? this was previously listed as a jj set, now it says jj/tesla.

Nikola Tesla was an inventor, electrical engineer, mechanical engineer best known for his contributions to the design of modern alternating current. How JJ co-opted his name is unknown to me. As for the tubes I am not a fan. I tried them several times in different amps and beyond those suffering infant mortality (nearly immediate failure) I found them to be short lived overall. I pretty much stick with TAD (Tube Amp Doctor) tubes these days. They sound good and the failure rate is very low. Strictly my opinion, but I hope it helps you with your decision.

Q: Will these work for a blues junior 1?

They work and still do, a 12AX7was bad, so bought a set ans have new extras, different valve/tubes. they work fine
