Re: Panick, Please Help 12v in VCO

2005-03-10 by Kris Bishop

I cant thank you enough, your mail came through an hour before the 
money transfered, now canceleed and the remainder of my components 
have been ordered through Farnell.

I don't know how I missed them I searched the site and even when 
researching autocomplete came on and then I found them.(HArd to 
believe I've studied Computing for 4 years, Bloody Scottish 
Engineers lol)

Anyway thanx you saved me time and money, and you put a smile on my 
girlfriends face(which is hard trust me). 

I now only require the mains transformer with 2 18v secondaries does 
anyone know where I can get one, this is my last component that I 
need. Hopefully the PCB's Will be printed by next week and I'll have 
all my components in.

Cheers mate
Kris
