Quoted from G-P-E:
On-Semi was the last major seller for these SCR's and discontinued them a couple years ago. I bought about 15K of these when On-Semi listed these on LTB list. I still have just over 6K remaining.
Since then - Central Semi has taken up the slack but at increased prices.
Littelfuse has taken over several product lines of SCR's and include some that are rated close to the 2N5060 series. One of these days - I gotta figure out which is closest to the 2N5064. Surely gotta be cheaper than the Central Semi parts.
Lastly -- damn, I love being on vacation!
Glad I read this post. I had a couple lamp drivers with this problem. I did go ahead and change out a few of the 2N5060's even though they tested good. I jacked around with the DMM leads and tested in a bass-ack-ward way and I was able to discern which were actually bad (less jacking around with the schematics). I think I replaced them with 2N6051's I got from Ed long ago, or a while back anyway.
Have those gone the way of the dinosaur also?
May 3rd tomorrow, hope your rested up and ready for the avalanche brother?
One other thing I have done that's sorta' cool was to actually get organized by using the Plano plastic organizer boxes (Menards, Home Depot, Lowes) for all the stuff Ed and a few other sellers - sell. If you get lucky you can peel the label that comes on the bags from Great Plains and put it in the compartment of each device. Saves on using the label maker, on top of that Ed's labels have all the info for the device...cool like mad. I have a box for Gottlieb cpu's, Bally mpu's, Sound board caps, Solenoid driver rebuild stuff... and about 15 others. Watch out though, those boxes multiply like pinball machines.
