Well after MUCH trials and tribulations.. I gave up. :) I lack
Since I'm picky stubborn, I do my own designs. That way I can only blame
myself. Snarkiness aside, making a production-worthy design is not trivial
and I'm sure that the few kits that are available are designed by engineers
who have day-jobs as well. On top of that, kits need to be affordable,

It is a Japanese type. but their are probably hundreds that would work...
use the specs in the link above
Kiran, PM me...I have all the parts you need and can send them to you for the
price of postage only.

Well.. I replaced the voltage regulator with JT's part, it appears to
be working perfectly.. a solid 5V right on the mark. I also replaced C1.

I suspect they will solve the problem but at considerably more cost than two
small capacitors which should have been there in the first place. ...

Something I want to note about how I used a heatsink; I epoxied it to the tops
of the cases of M1 U1; traditionally you'd bolt
will accelerate the dryout of any nearby
electrolytic caps.

Could you have a faulty DS1307? Would that cause a timing issue?

The voltage from the wallwart (12V, 1A) is 11.8V under load. The high
voltage to the tubes is 172.8V. It's very difficult to get it right at 170V
when adjusting R26
