Well I am really not sure how this forum is supposed to work. It seems that I cannot post to the last reply and my thread seems to have been hijacked.
However, I am pleased to say that thanks to the input from Dieter on diagnosing the failed IC03 (UCC38084D) I purchased some replacements from Mouser and decided to take the plunge and bought one of the (in)famous 858D hot air clones and after a bit of practice on some junk boards I felt confident enough to start the surgery. Actually doing the job, was not difficult just a bit stressful. After removing the old chip, I dabbed a bit of flux on the board pads from a flux pen and re-soldering went very easily. All went well and as I plugged in the 12V supply to test the voltages, the neon colons were happily glowing. The clock is now reassembled and back in its place in my showcase glowing as good as ever. So once again, thanks to all who chimed in on this and a special thanks to Dieter for his very quick support.
