[Amps] Why are 833s so Expensive

[Hsu]

Hi Roger,
  I live  near one of 833A's manufacturer.only 1km haha.
Now, the 833A manufacturer's list price is CNY 600 orso, ( no more than $100)
But if quantity what you want  is big, I think it should be lower

 there are  two 833A's  manufzcturer,  the factury  nearby is the best.
 But few people would like to do this bussiness, because the 833A's weak 
filament, very easy to damage.
    73!Hsu
