Re: Epi valve Jr v Blackheart Killer Ant
I had a Little Giant, the 5 watt amp (EL84 + 12AX7, just like the Valve Junior) and it had no hum and was very well made.
The Killer Ant, in my opinion, has very little, if nothing at all in common with an amp like the Valve Junior.
The tube complements of the Valve Junior and Little Giant are identical, while the Killer Ant is quite different.
Valve Junior: 12AX7 -> EL84
Little Giant: 12AX7 -> EL84
Killer Ant: 12AX7 -> 12AX7
Both the Little Giant and the Killer ant supply DC power to the filaments for super quiet operation.
To be fair, the Valve Junior runs DC to their filaments as well.
I have played single coils through a Little Giant for about a year in a basement with fluorescent lights and a computer, and never had any noise.
