What is the tr. characteristic(s) to check in datasheets for Millenium 1 and 2 ?

[frank_p]

I am having a hard time finding a P ch. JFET or MOSFET for the Millenium 1 and/or 2 circuit for using in a positive ground / negative supply circuit.  When looking in datasheets, what is the characteristic variable name to look to and to be close to (what values) ?

Thanks !

So the MOSFET  BS250 might be a better solution (than the J176 FET)...
Gonna search again...

Hi Frank, I've used the BS250 and the TP0610KL in a positive ground Easy Face. They share the same Vishay datasheet but have different pinouts. Bought both at Digikey.

Today, I've been searching in Montreal for the J176...  and equivalents.   I toughed that you could find anything in my own city.  I wished to, this is the best way to support local diversity.  Even Mail ordered: it seems to be a problem.   So a look for the Millenium 2 with mosfets P-ch. , as suggested on the forum: this was in plans.  Well it seems to be the way to go now... But I still have to mail order (is a thing that I don't like).  I am willing to pay a little bit more to buy in Montreal CA. : So, to support the local industry at the least price for a LED indicator circuit.

Try the CD4049 and do a Millenium C.

Thanks R.G. gonna check that.
