唔識嘢請指教

膽機擺喺個倉到幾年都冇用過。
手痕行的返屋企試吓。
插座電源之後完全唔着。
小弟啱啱入門玩cas. 想試吓玩膽機
睇下有咩唔同組合。
乜都試吓。
Ching 大佬可以解釋一下嗎?{:9_419:}

師兄件野好特色，有機會影下內部look look 嗎？

"隻膽正確嗎? " -- this's a good question  !  and that's the reason for my request of a "OPEN VIEW" of ur antique.  

it appears two rectifier tubes were (or to be) installed.  Or, that tube was wrongly located .......Oop~~,  as u said"  FUSE 冇斷,.....見D其他相有大有細,..."

兩隻膽係一樣.
我指大細係見到其它機通常裝4大2細膽
個座有個凹凸位同隻膽一樣,得一個位可以裝上去

兩隻膽係一樣..... I can't tell more, until u show the "OPEN VIEW" of the unit.
其它機通常裝4大2細膽..... those 係integrate/pwr amplifier, not the type of yours. (see pic below).  YOURS is a pre-amp.

個座有個凹凸位同隻膽一樣,得一個位可以裝上去.... that's fool-proof for orientation.  it doesn't prevent u from installing the WRONG tube(s).

may be, yes may be...... the right tubes are 6sn7.  hv u ??


stop installing any tubes.....

5v4g是整流膽，
師兄內外影個全相吧

ADA

都係果句, 影張開底蓋相看看就清楚了.
如果樓主你肯定這2支膽係這部機用就一定係左右位問題,
但因為這2支膽的特性及接腳是完全不同的, 所以最好唔好再通電試了.

亦有可能5V4G不是這機用的, 見你部機後面有2組輸入輸出, 又有粒拍拍掣,又有獨立VR,
...這組合比較奇怪, 以前是否電子分音用的?

打開之後我都俾佢嚇親

那二個膽座唔係 5V4G 亦唔係 6SN7 的.
