醜女大返身之 -- KT88 (Part II)

Dear Cat & accphoto,

Kindly share with us the finding after u had done the troubleshooting..

TQ

Dear Cat,

So finally what's the main cause of the "sss" & "bu bu bu" sound on your KT88? How you both solve it? is it because of faulty part or connection problem or grounding problem?

Dear Cat,

Thanks for info.
We learn something new.
