Toy12 Plasma tweeter 離子高音 Diy-12 change new flame needle


Before change the flame needle always cause noise.
This is first time to change new needle.


Too busy so have half year no clean flame needle.


Below one is new.


Finish change flame needle.


This is more worse flame needle of Another channel .


After long time high temperature and a little bending the flame needle crack away.


Siemens PL519 almost run out left time so I change cathode bias to drive more plasma flame.

Because Siemens PL519 tube is hard  to find .

My wife coffee shop's amplifier


This Pioneer amplifier working over 15 years.
Fix two times already and always one channel broken.



 
So I buy a tube amplifier on internet.
12AX7 + 6AQ5 + Look-T Opt and diode rectifier with Look-T chock.



 
This Amplifier had been modify so many time.
With Opt second side feed back to 12AX7 cathode bias.




Take off Opt second side feed back to 12AX7 cathode bias.
Modify 12AX7 and 6AQ5 bias and change couple capacitor ...Bennic cap not good.

走過咖啡店早年歲月

咖啡店從無到有... 從有到無... 歲月的流逝 ,剩下的祇有記憶.

從無到有--- 舊店設立.
從有到無--- 拔營....牧咖啡的咖啡人.....移址, 啡客...........的遷徙.

咖啡店=咖啡+音樂

咖啡=日式咖啡+美式咖啡
日式咖啡=日式單品+日式花式咖啡
美式咖啡=美式單品+美式花式咖啡
.........."請不要找茶".

音樂=古典音樂+真空管
