Firstly Hi All, I've read with interest this forum, and decided it was worth joining - so here I am! [CODE][/CODE]I've bought an old Trilogy VTi integrated amplifier. Its beautifully made and I love the sound yet one thing bugs me :confused: , at low volume ther is a noticable hiss, which is very pronounced in the left channel. My speaker is quite close to the amp on that side so I swapped speaker cables round at the back on the channels to see if it was interference. Then the hiss came out of the right. so its definitely something to do with the left channel. This amp uses a pair of E34L and ECC83 valves on each side. It has recently arrived in transit, so I'm wondering if it got drop-kicked from London. I had a look at the walrus forum, and stuck a mains filter on to no avail - any clues? Thanks!
