Tube Amp Archive

thanks for the replies.yes,i have an 12ay7 at v1, and 5y3gt at v5 and not weber's wy3gt.where is more possible to have a cold joint?maybe at the tube's grounding?

thank you cbass!

yeah,that's exaclty what i want to say cbass

yeay, i've tried at both inputs, both channels.i've played with the same guitars in another 5e3, too, which also have the same "problem"

that's great martin,thank you!you may think my english is good,but i couldn't understand this sentence though haha Sliding heat shrink or even 18 gauge wire jacket stripping over those resistors on the input jacks should be done. rd jones,that's an optical illusion of the photo,they are not touching...

thank you tillydog,i'll re-make some of them and posts the results!thanks again!

well,i've got some news.my amp finally plays as loud as it should be,after cleaning as tsutt adviced me.however,the problems do not stop here.sometimes(not always), the volume pot at bright channel do not work,it plays at the same volume,wherever i adjust it.and the sound is now distorted at both ch...
