Assemble and estimate rack design. I put Aluminum plate in each layer for shielding RF influence.


Paining wood racks for good looking.


Prepare Layer 1 components and parts.


After placement design and finish assembly Layer 1 module for Plasma tweeter high voltage generate.


Put Layer  1 module into wood rack and estimate hand make process flow.
Put  in step by step list.


Design Layer 2 module and put in wood rack for estimate hand make process flow.
This layer module main function is feed Audio-in and generate I-F modulate signal.

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
