I gave up on eBay parts when I realized I could usually find modern versions of the same parts on Digikey for the same (or lower) price.
Here is the plastic case alternative for just $0.14 each. Obsolete like the tin can version but much less risk with Digikey stamp of tracking and tracing approval.
Order today, ships today. TN3019A – Bipolar (BJT) Transistor NPN 80 V 1 A 100MHz 1 W Through Hole TO-226-3 from Fairchild Semiconductor. Pricing and Availability on millions of electronic components from Digi-Key Electronics.
Just to stock spares for my 50yo 'scope. I don't know if it uses those exact ones, but I noticed a few TO39's from that seller, so s/he may have the ones it does use. Just one of those things I keep an eye out for. I find it sad if I have to resort to modern substitutes.
