Perhaps a caveat is needed here, and that is, if you have
old as-new stocks of wire-ended components, (with the possible

Also, if you're moving in the direction of SMD, then
the easily-installed 1206 former larger sizes are
something to get hold of while you can.

My regret is that a couple of years ago in a clear-out,
I binned all my "geranium" semiconductors and RTL logic chips.

I've not had a problem sourcing any discrete components as yet. Via mail
order. The days of having several shops round here that sold them long
gone, though.

Some things are more difficult to get and come at a price watch out.

74LS76

£6.60

~£4 for five but £7 P&P

We had to scap these from a lab because we couldn't get them reasonably priced
and that was over 5 years ago.

They used be be 25p or so.


Russia is a happy hunting ground. The Old Soviet semiconductors are
usually straight copes of western components and work just as well.
And they are usually a few pence.

I wouldn't send my CC details to a russian company.

But if anyone can provoide a link to some reasonably priced 74LS76
then I'd be interested, we'd need about 100 to start with.

But personally I;d prefer we teach our students how to use cpmponents that
are currently easy to get a a little more modern.
I;m pushing to go exclusively to the HC series.
Not interested in the 7400, or 74LS, or 74S or 74F or 74ALS.

Some chips/components are getting difficult to get as 'through hole"
