THE GREAT MULLARD MAGIC BLOG

My 11-year-old nephew Mikey was smiling at the array of master and slave clocks in my shack.   Mikey did once proudly tell the curator at the Malta National War Museum at Valletta that “Uncle Steve has an RAF sector clock” but this time his interest was piqued by my ship’s radio room slave clock pair which are a Seiko QC-6MS and a Citizen TX5 5S being driven by the Power Station Synchronome master and he was asking why these clocks had different sectors to the RAF clock so as I was telling him why, I realised that others may appreciate the...

Mama Mia!  An e-mail from Vigata in Sicily enquiring about when certain valve bases were introduced.   I know a valve dealer from Sicily you know, he's from Messina and ever such a nice chap but I digress........
