Thanks for sorting it...
That sort of transformer is going to work fine. The clock uses a lot
less than 15VA - I used that size for its availablity and donut hole
(not potted) to wind on the heater (filament) supply winding. In
practice you could use two smaller transformers 2x 0-15V plus some sort
of 6V transformer. You could also use a transformer other than a
toroidal but most other transformer designs have a stronger external
magnetic field which would require a larger spacing between the scope
and the transformer or shielding etc Lots of tunes to play.
