Replacement JFET for ASM-1 VCO

[Dr Steve Grainger]

Dear All,

	Found an interesting page on Siliconix's site :-

	http://www.siliconix.com/www/product/nchjfet2.htm

	This has the data for their 'switching' JFETs and the J109 looks
	a good replacement for the 4391 type (and its available from Maplin
	Electronics in the UK) In fact it seems to have a LOWER ON resistance.

	I'll try and buy some tomorrow and report results later this week.

	Regards

	Steve Grainger
