Default Why the GZ34 Rectifiers are so expensive!

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.

Greetings,
Andreas

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.

+2 Absolute nonsense - like that silly thread recently offering six E88CC at $950 - this though is even worse.

I do not believe in the "sound" of rectifiers; how can they have a "sound" when there is masses of filtering around them?
