Patron selamlar, sana mesaj attım ama almadın galiba...Benim Vox hakkaten bitti, adamlar haklıymış Opto-coupler ayvayı yedi. Nerden biliyorsun dersen bu alet amfinin üzerinde Tremolo efektini yöneten bir parça ve şu an tremolo efekti çalışmıyor. Korg'un teknik servisine telefon açtım. O da aynı şeyi söyledi. Zaten adamın eline bunun gibi bir kaç şikayet daha gelmiş. Aynı amfiye yönelik. Tremolo efektinin çalışmadığı gibi amfide ciddi bir Volume kaybı da var. Bu da onunla ilgiliymiş. Ben konuyu sana tam olarak anlatamıyorum. Bu yüzden harmony-central'dan bir alıntı yazıyorum : "FOR ALL C30 OWNERS!!!!! READ THIS!!!!!!! THIS IS VITAL !!!
The villain of all bad reviews of this amp has a name and location!! it is a crap part that was used on the amp! it's the opto-coupler model LT9914 which is responsible for the tremolo and its located on the circuit board next to the volume pot, all users MUST change this part for a VTC5L3 optocoupler!! even those who didn't yet have the problem. All you hear about crappy sound, low volume, volume variation while playing (after getting warm).....here is the solution besides, there's two pot's called VR11 and VR12 on the C30 Circuit Board that happens to be (most of times) not well regulated, they alter the gain that is sent to the power section of the amp so, when it's not regulated makes in some amps sound crappy (Clipping) ! I also made the modification to 60W don't be mistaken these amps are a bargain! they just need a little tweaking!! I'll give you another important tip check this site www.voxtalks.com the truth is outhere! :) YOU HAVE TO DO THIS GUYS !!! THIS AMP ROCKS! FORGET THE BAD REVIEWS, that's why you see some excelent reviews and some terrible reviews!! DONT WASTE THE CHANCE TO HAVE AN INCREDIBLE AMP FOR A CHEAP PRICE!!! OPEN YOUR EYES AND CHECK THE VOX FORUM !!!! I was about to sell it when a optocoupler went off, thanks vox for using such a crap in it! now I have a fantastic amp! after my research about the problem! One thing I don't understand if VOX put a IC Power to 60W they could ask twice the price! it sounds SO MUCH BETTER you have no idea..... To change it do 60W you just have to change the original IC POWER which is a TDA2050 for a LM3875 (my case I used a LM3876) the best is, the 60W IC costs about 5$ US dollars!!! 2 hours job separates you from a FANTASTIC amp" İngilizcen yoksa çevirisini de yollarım sana. Yardım ve tavsiyene ihtiyacım var.
