Must have mojo parts

Ahoy!
I consolidated some of my parts storage and suddenly have six glorious 4x4x2" drawers sitting empty. Naturally, my first thought is - what obscure mojo parts can I start hoarding with zero intention of ever actually using?

I'm getting into breadboarding and experimenting with the handful of PNP germanium transistors I’ve got. Those are as "mojo" as I have got.
I have a hefty stock pile of standard stuff you can get at Tayda or Mouser.

So… what am I missing? I need to fill these drawers with pure TOANZ!

What are some must haves?

Got a good stock of J201s from here, set on that front.

Soviet diodes? Japanese diodes? Free range organic diodes?

I got a bunch of old germanium diodes from stompboxparts to experiment with... I'm afraid they instantly sell out of them free range organic diodes whenever they get them;)

I just ordered some NPN and PNP Germanium Transistors from ebay SOVCOM seller seems legit. Kinda went down that rabbit hole and had to get something before all the good ones are gone (all the really good ones are already gone or horded imo)

the big three LM108/208/308, metal can CA3080, TA7136AP ... metal can op amps in general give off big mojo energy

maybe some Russian germanium diodes or transistors, definitely some of their op amps and silicon transistors and diodes (like the Sovtek muff)

those NPN germanium top hats from RCA that Smallbear used to carry are pretty magical and you can still find horde quantities of 2N404

I wish I had more Telefunken BC108/109 and some lower gain silicon transistors in general come in handy
 
I got on an OCP71 kick for a minute... it appears they are fairly available and I got about 50 pieces of them online a couple years ago to play with... rumor has it they were higher graded OC71's and used as a more expensive phototransistor..... When you put it inside a dark enclosure and not exposed to light they are an OC71 tranny...

In an interview I found with a former Mullard engineer, he said something a long the lines of:
It was a different process than the OC71
OC71s had a different process/specs.
If the unit is failed screening to be OCP71s, they were re-evaluated to be used as OC71s. But it was only a portion that were reused as OC71s.

So basically, a functional overlap.
Also, keep them away from red and IR LEDs
