I'm trying to make a NOTC relay. I found this:
http://forum.allaboutcircuits.com/threads/time-delay-relay.22874/
but none of the links to the actual circuit are still good.
I have a vague idea of what the circuit should be given the discussion about it I was just hoping someone had a working picture of the circuit.
That said, what I really would like is to make the switch in the picture close after some time.
(picture from http://www.valvewizard.co.uk/standby.html) Just like the link of where the picture is from I'm trying to slow the application of HT to a tube amplifier. Really what I would like is to just flip the ON switch for the amp and have the heaters turn on instantly, then have that switch close after 15~30 seconds automatically. Because of this, a very ideal circuit would be something that is powered by 120VAC (turning the amp on).
Any ideas on how to make such a thing would help.
Thanks all
