Lets face it, anyone with Sparky in his name is either a dodgy chap who works with live wires or has a talking piano.

Showing your age there, Bernard...

True, and I see that your campaign againgst The Sheds is starting to take effect

I did often wonder what a "shed" was

Genuinely had BAS down as a guy who dislikes garden huts?

Sorry B-A-S. Misleading username? - no, I cannot let that slip past!

origin of the trade, or rank nickname "Sparky" or "Sparks" was (usually seagoing) radio (W/T) operator.
Actual (rf) sparks were an inherent, necessary and occasionally spectacular part of the first generation (no pun intended) of long-range W/T Tx gear, I won't insult your ignorance by going into the details of why.

Circumstance, policy, common usage and technical ignorance has led to the term becoming applicable to those who often work with electrical cables and wires (though not necessarily electricity!) although in general now the term "Spark" appears to be common usage in reference to an "electrician".

However, as I have suggested before on this forum, sparks are certainly not an inherent or necessary part of the equipment or trade of an electrician - nor have they ever been.

If I may be permitted, I would further suggest that a Spark's frequency of sparking - in the time-domain at least, should (hopefully) decrease with experience, whereas a Sparky's frequency of sparking would ideally increase with experience...both in time and frequency domains.

Misleading username? sorry, no. "Heritage" username? possibly.

As I am qualified in the trade that is (was) supposed to produce sparks yet unqualified as an electrician, I probably produce the most sparks of all....

after a further incredulous look back at a genuine & honest technical enquiry once again derailed by the disaffected, it strikes me that certain of us might do well to remember the amazing gift of bandwidth that we daily abuse at our fingertips.

BNC - sorry, mea culpa. I meant Bayonet lamp connection, not the Niels-Consulmann type.

The Singing Arc transmitter, used modulated interference from a massive spark to transmit speach and even music (?)

Misleading username? sorry, no.

Sorry, yes.

This is an electrics forum, and in that context the word "sparky" has only one connotation.

That it means, or used to mean, other things in other contexts is irrelevant. Here it means electrician, and nothing else.

Now that I look again at the photo, the connection to the metal backplate does appear to be an earth.... I no longer have the lumi to hand, but my initial glance seemed to show one of the Bayonet terminals connected directly to the backplate also. That does seem unlikely.
thanks all for help.

I wondered whether the hot wire ballast was perhaps a wizard-wheeze to heat up the tube a bit and get it fluorescing harder...?

This is an electrics forum of which I am a grateful member: As such - and as I have just demonstrated - the word "sparky" definitely has more than one connotation. I have simply drawn attention to its origin.

The word "electrician" means "electrician" and nothing else.

if nothing further relevant to bring to this thread then pse qsy, preferably qrp.

No.

AS SUCH it does not - AS SUCH it has only one.
