Does anybody know why these seemingly ordinary tubes are going for ridiculous prices? for example look at this eBay auction for two nos GZ34. Only $1900ish. Why I'll take a box for that price!

I've a 1955 metal base GZ34 that I found in an old 807 diy amp. It's bound for a "suitably fashionable" home when I get a "suitably fashionable" price - 😉
Bought JJ GZ34 for a few Euros/piece. Work fine, though I have to admit that I only used them with a choke-input supply.
Some people claim that new production GZ34 are somewhat fragile with large filter caps behind them.

They sound much, much better than current production GZ34, specially in resolution and treble and they last for decades ...
One of these I have in my amp more than 10 years ... Metal base GZ34 / 5AR4 made by Philips

Especially when you're a tube seller.😀 If they caused a difference in "resolution" and "treble," then the amp is bizarrely incompetent in design and/or construction. And I've never experienced an amp THAT badly designed.
I've got a fair number of vintage English GZ34 in service, and the one thing I will say about them is that they are reliable in way that no current production GZ34/5AR4 is. No failures at all in 15yrs.
Better regulation under varying loads and less forward drop than current production JJ, Sovtek or Shuguang 5AR4..
I hear no difference in performance attributable to brand or vintage of these tubes. (Reasonably well designed regulated supplies)
And I definitely couldn't afford to buy them today... FWIW.. 😀

the entire point of tube vs silicon is controversial anyway.
i bet the dead engineers at phillips would turn in their graves if they just knew 😛

yeah phillips. the major part of the metal base stuff is 😀
anyway i guess it goes for engineers worldwide

I'll second that. The only difference i have noticed is in reliability, and price of course. I see a trend in people who have no knowledge whatsoever regarding tube electronics driving prices through the roof based on silly claims they have heard from so-called "experts". (read- tube sellers looking for more money)
Do you know why these seemingly ordinary audio cables are going for ridiculous prices? For example look at this company's claim. high-end cable
Bottom line is, it's not just limited to audio cable vendors.
All the JJ GZ34 I've used, they seem to last 4 years max. Music for a few hours every other day. Vintages are just too pricy nowadays. And I too don't believe in "sound of rectifiers". I smile when I see the designed and constant 430VDC B+ when I stick that voltmeter red color probe there.

Overpriced rubbish my electronics supplier had a one time offer on 500
1N4007 at 1 cents each 😀
@ those audio cables .
I had a supplier selling RCA plugs two females for 70 cents/Set gold plated ofcourse
i laughed Real hard every time i saw A 500 dollar interlink use those connectors
