I have an L-48 from an estate. very clean, however, I do not know how
long it has been since its been on the air.
Plan to bring it up on a variac ( its wired for 220). Curious as
opinions on how long it should sit at reduced voltage.
Also looking for any known safety or improvements (components)
recommended for this amp. I'm not looking for additional power.
Appreciate any recomendations.
