This series is still TOTALLY under the radar for some reason.
Even on e-Bay, they go for cheap.
Insanely well made, though a bit of a rats nest inside.
The Alps switches are almost military grade, the front faceplate milled out of thick solid aluminum.
I completely rebuilt a 7055, with all new caps, including filter caps.
It sounds fantastic, and it's now my daughter's daily driver.
Have a 7065a waiting for the same treatment.
Can't say enough good things about this line.
Super bargains, for quality of sound and build.
