Hell the fact you can still source the same components, over such long wait times especially, is just as impressive.
What components are you talking about?
About the NOS RFT EL34? - still 24 quads in stock and 60 pcs. more on the way. Additional still 9 quads of the NOS Mullard EL34 remaining.
About the NOS Tungsram ECC83? - still about 200 pcs. in stock. Additional lots of NOS Mullard, Philips, Siemens&Halske, Valvo & Brimar ECC83s.
About the NOS Cinch and ELCO B9A preamp tube sockets? - still enough for 25 more Larry amps in stock (all individually packed airtight).
About the NOS LCR 50-50/500V can caps? - well stock meanwhile is shrinking, but the currently available ARS is a spot-on rebuild of the good old Daly.
About the NOS Dubilier Cornell 170 polypropylene caps? - still all required values for about 50 more Larry amps in stock.
About the NOS British Imperial M6 sheet metal for my custom made transformers? - my tranny winder in the UK recently found me 180 kg of it once again.
Yes, if you buy enough in time, you will have enough for the future later

And I additional have good contacts to people in Poland, Hungary and Ukraine, who always find old NOS components for me again and again
Sometimes however it is unfortunately the case that components that have long been out of production can no longer be found anywhere.
That's why I had to switch from my beloved Belling Lee fuse holders to a currently produced type already years ago.
Or my beloved Arrows switches for power & standby on my British Purist & Rock Wizard models are nowhere to be found anymore and I have to use currently produced types for them
But don't worry about it too much and believe me - in 100 years at the latest no one will be talking about it anymore anyway
