quad 606 mk1 problem

kokheng · 3rd February 2009, 05:33 PM

recently my quad 606 mk1 start to sound funny, broken sound (low frequentcy) can be heard on the right channel only on certain frequency whlie left channel perfectly normal. I've swapped the speaker cable from left to right and vise versa, it is confirmed that the broken sound coming from only the right channel of the amp.

Please can someone advise what is the problem with the 606?

Thanks

Hi Alex,

Thanks for your respond, actually all the e-cap had been changed to audio grade e-cap except the 6800uf power tank. It is really a worth upgrade of the cap as the sound quality improve a lot af the the change, but the broken sound issue remains unsolve.....
