Marshall DSL15C/H DSL40C schematics

[lowell]

Per the schematic it looks like V1 preamp tube runs off 12vDC and each half of the filament should have 6vDC. I'm getting 5.17vDC on each. Anyone think this is too low? Customer says he thought the amp wasn't as loud as it was (love it when they say that). But I assured them it's working great... it gets very loud when turned up as the pots keep it quite low till you get em up above 5.

The link in post 2 is missing. Anyone got a schematic for this amp? NEVERMIND... links don't show on mobile.

Mains fuse is integrated in mains socket.

Are you measuring 'open' on the primary?
It's possible it has one. Could be a broken or burnt wire near the terminals also.
