I don't know about worn components, most caps/resistors in those old Laneys are perfectly ok - some amps just ain't that loud and it's natural for a booster to get them much louder (specially if it's the one I sent you, lmao) :lol:
Old/worn output valves will cause loss of volume/punch so it may be worth looking into that but I doubt all three amps are on the quiet side because of worn components.
:twisted:
