Hi Ron
Thanks for the information. I'm a complete novice . I bought a cheap 'scope last week to play with and get used to when & how to use. I've spent the weekend stripping it down and removing several Kgs of dust etc, reassembled and all is OK. I decided to get a signal generator to use to play with the 'scope to get used to it. I don't want to buy one I want to build it, just for the hell of it really, and to extend my experience.
If I can use ceramic caps, thats fine, I've used before so they are familiar. The XR2206CP is obsolete at most suppliers now, but there are many available on Ebay.
Good to hear from you
