[#76] etsang3 修理好聲"山水"機一部    
Good morning etsang3 hing

Great Hint!!

almost forgot the "soft clip" circuit.

I suspect 10000uF filter cap but it look perfect, no sign of leak or swell, try switch off the soft clip and replace filter cap first.

THX

Wo hing, please check (LOOK) from this direction for parts condition and soldering.
Power Plug -> power cord -> power cable clip entry hole -> power switch of amplifier -> power fuse holder -> transformer wire soldering ->rectifier -> Big filtering cap soldering and connectors to the power amp PCB.
I am afraid the problem will only happen when the current flow is prolonged and that problem point is heated up.
Also, please try to knock on the amp without playing a music to see if there is any abnormal noise.

bbqiller hing, I missed your question.
What amp you want to change from 110V to 220V ?
If the transformer primary side is multi-taps it cab be changed otherwise need to change the Transformer.

唉!部AU-D9又番鷑,發覺燒鑆ower管,無理由100零mA BIAS會燒power管假,細看原來都係Remark貨。我幫襯開果間(好似轉鬫挐)都賣remark貨,真失望。
換過哂 D On-Semi power管,又再Boom..Boom..Boom..鰲X粒鍾,明天可以call機主囉機苤C
<<請認住呢D假,7DY?大細字?)

On-Semi MJL1302/MJL3281 ,Mark機都用,十分好聲,聲音好通透,因為fT高,比Sanken管好D。Farnell有得買又唔貴
。最重要肯定係正洁C
