They don't sound the same..to me, original > replica > clone > homemade. My 2 cents.
The black beauty caps for coupling is $60 USD a pair now (one of the most important parts)..lol....doubt it if it could be found in HK., wouldn't be easy anyway.
Sometimes, people think bumble bees are black beauty (both black), like the one who did ST 70 mod, he mixed one bumble bee. Bumble bees are not good, due to easy electricity leakage.

Cap called Vitamin Q is just as good as black beauty, just half of the price..
Hard to find mint condition due to age....needs new parts. Only if you know which parts and how..different part/tubes/transformers result different sound.
