I hope that's not true.. only two years use..yikes..

It can last years if you rotate tubes ...... But sadly, they won't last forever.

You have the clear-top. So there is no need to hunt 421A. I have about 5 pairs of those, and haven't touched the 421a for a long time. Tubes are consumables....it will die or degrade in 1 or 2 years.

This is more alarmist than factual. On a purely technical basis, yes, tubes start to degrade the moment you plug them in as electrons start to boil off the cathode coating. How long the tube ultimately lasts is dependent on the quality of the tube itself, how much it's used, and more importantly, what voltages it is subjected to in the particular component. I have a pair of 300B's (outputs) and CV378's (rectifiers) that have been going for almost 20 years, and still sound as good as a new pair and still test quite well to boot. OTOH, if anyone remembers the Audible Illusions Modulus 3B, it ate tubes for breakfast. 6 months tops, and usually less. The tubes were juiced SO hard that some vendors (like Upscale Audio) ceased selling tubes to anyone using them in that preamp. On a more normal basis and assuming a tube is run at reasonable and conservative voltages I would expect most octals (small drivers and even power tubes) to last 5 years with minimal degradation. Rectifier tubes can last 30+ years if they are run conservatively.

This seems to becoming more prevalent in recent times and I don’t fully understand why? It has been suggested to me that to post items outside of the USA you have to visit a post office. Whereas internal post can be collected from their mailboxes at the end of their driveways?

Maybe something like that but it's just a trip to the post office... I don't get it. I'll even pay 60 bucks to have it shipped via UPS in 5 days but most seem to deny my offer

I think we forget how vast the USA is. I can walk to my nearest post office in 10 minutes, could be a 60 mile round trip plus in the States.

Yes, off eBay last week.

Currently working on securing some of these 1953 WE 5998/421A ...

IMHO, stay away from these greedy Italian sellers, they are likely some aliases of the notorious "Italian BangyBang" wege_high_tubes, aka BangioBang (named by @jonathan c )

you mean they are an Italian political party?

 

[cddc]

LOL...there could be a BangioBang party, a branch of the American BangyBang party

 

[cddc]

We've known some members of the BangyBang party - BangyBang, Menifee_Audio, FallAngelFall, etc.

But little we know about the BangioBang party, other than wege_high_tubes.

 

[bcowen]

Probably more like an offshoot of the Italian mafia.

We are under attack from the mafia.
