hi
i’m from italy.
i recently bought an english muff’n on ebay.

after a few minute i have noticed a drastically loss of volume and a large amount of high distorsion and hiss.

this happens sometimes and it’s a problem, in fact i can’t bring it on my gig.
i have noticed that if i touch the left tube i can hear a little “toc” on my speaker.
so i have changed it with another ehx 12ay7 tube, but nothing happens.

sometimes if i plug off and then plug in the input jack, that problem stops… sometimes not. and sometimes it starts since i push the on button.

anyone have had a problem like this???

sorry for my english.
