[#1] 膽 Tester for 6550 & 6H30    
請問有什麽膽 tester 使用簡單又唔太貴可以test 到 6550 同6H30 的狀態? 邊到買? 大概幾錢?
Orange VT-1000 本來是一個好的選擇, 但只能 test 到 6550.... thx

樓主要明白6H30係前蘇聯軍方獨家研發,一般歐美古董試膽机未必測試到,AT-1000 spec就寫左測試到

ARC?

6h30 has no old tube.. Just buy from reputable online shops will do.

For 6550, i would do the same and not to be bothered. I do have tester for 6550 but I need to have many 6550 to be able to match properly. As well just order from shops in pairs/quads....

市場上冇 old tube? 定冇NOS (New Old Stock)? 我係指NOC, 例如:

Those are relatively new tubes and should have no problem getting from reputable shops matched. (Not telefunken or mullard type of vintage age from before 70s.)

6H30-DR is fade out already since 1999. There are many fakes 6H30-DR in the market:

Tube testers will not be able to tell you whether a tube is fake or not fake.

1999 is not far away. I googled and immediately found a reputable store that sell them. Whether you wanna pay for it is another question....
