On this front I recently found a source of the small wire-ended neons that I am sure we all were familiar with wired across the input transformers of Command Receivers and the like (I'm showing my age again !!) Neons take a few millisecs to fire but anyone who has them fitted with be aware of the little flashes with a non-earthed aerial that occur even when there is not any nearby thunder. I think they fire at about 70v. The neons are order code Z2459 from Greenweld at £2-50 for 10 www.greenweld.co.uk from the March 2001 cat. They often have odd values of high voltage (250V to 1kV) capacitors at reasonable prices. Cheers de Alan G3NYK Alan.Melia@btinternet.com
