Smart buying buying a preamp with tubes anot avail except as made by preamp manuf?

No amp or preamp manufacture actually makes their own tubes. NONE! So what kind of question is this?

If they use very rare and expensive tubes than it's a good reason to stay away from it.

Valid post. No need to mention co name that sells good products, so i didnt share co name.

tubes are a challenging area. 

Moderators,

You do a fine job deleting threads that contain opinions you disagree with -- yet you allow bullshit topics and threads like this one shoveled by @emergingsoul.  SMFH.

there is no such amp. amp makers make amps. tube makers make tubes.  next!

Well it's certainly one way to make sure you have a corner on the market. I'm sure I'd make a great milk carton pic. Holding my single tube. "Have you seen this tube"? If you have la-te-da..... :-)

Is this another troll alert?

@emergingsoul "...he is only person making the tubes?"

Really?  

No way I would ever buy into that. Companies come and go… tubes require replacement.

What are you talking about?  C'mon man, you can't just post stupified posts about nothing!  if you have a problem with a particular manufacturer then make it known. If you are just doing silly high games then make it known! Don't waste our and the moderators time.

@emergingsoul please cut to the chase and tell all who's the manufacturer and what tube.

Tubes if found are $300 per.  No inventory anywhere.
what if manuf discontinues making special tubes in a few years.  Resale value of preamp is low. 

My luck. I buy one with a spare tube. Then someone else buys all the rest, all 15 units.. all 30 tubes.. Sounds like a nightmare. to me.. Next thing we read about "what a nice guy he WAS".

It might be amazing. With spares, it could last a lifetime. Small signal tubes (can) last a long time.

Op, if you are interested in some informed comments state particulars so everyone knows what manufacturer, what preamp , what tubes etc. 

I would
