I can't find the 2SA1266 transistor. Tried a cross-ref site and it gave

It is a Japanese type. but their are probably hundreds that would work...
use the specs in the link above
Since this is a TTL device, the transistors will be reverse-biased with the
supply reversed (power pins are typically in opposite corners, so
reverse-installation reverses power). With reverse-bias, there will be
almost zero current, therefore the device wont get damaged.

Thanks Niek.. I'll try replacing those parts you mentioned. The IN-18s are
socketed.. I wouldn't expect to have much trouble moving them to a new
clock. I'd hope not, anyway.
MichaelB.. I replaced C6 first, when I was having a problem with all of the
tubes lighting up all sorts of numbers
Kiran, PM me...I have all the parts you need and can send them to you for the
price of postage only.
Cheers,
Nick

The inductor; I know it's 'inductance' is 270uh.. but what current rating?
There's about 330 choices. :D I wish I could tell these things by looking
at the schematic.
