Default Tek 545B O'scope Fuse and Power

Of course the fuse takes care of the whole thing, it's in the primary to
the power transformer. F601, it's a 6amp fast-blo 3AG fuse for 120vac
operation (3ampts if running off 240v).

blow"
type.


It's a standard glass fuse, you should be able to get them anywhere.

I couldn't be bothered going down to the basement to check, the manual was
handy. The parts list says fast-blo. The odd thing about the manual is I
see no photo of the back panel.



** So the thick plottens .......

Seems there is disagreement between the manual and the labelling on the
back.

A "T 6.3" amp fuse is too big for a tube scope - but an "F 6.3" amp fuse
would be about right, given the inrush surge of the circa 200VA supply
transformer.
