Actually in another ten years there won't be any tube producing companys period. Kinda like a new shaker hood scoop for a 1970 hemi Cuda. 30 years ago that was a 60 dollar part.....new. Today there are very few new in the box ones left. They can command up to 10,000 dollars today.
Even if your model number tube is made new there is such little demand for them the price will be high. The only reason electronic parts get cheap is when they crank out 700,000 of them a year. I bet there are maybe 200 people a year that need your specific tube, thats why so much.
I'll bet that they make that many amplifiers a year or 10x that many!
LOL!!!
I had to laugh when I read the Ferarri comment. Years ago I had a customer who bought a Testorossa and found it wasnt up to par. I had to replace the clutch, pressure plate and flywheel, trans seals, and some other parts that I dont remember right now, and gave it an oil change and tuned it correctly, and you should have seen his face when he got the bill!!! Parts aint cheap or plentiful, and they are packaged pretty tight in there.
You know, ya gotta pay if you wanna play.LOL!
