JTM-45 Problem with High Treble channel and Speaker Output
Posted: Sat Dec 21, 2013 9:23 am
Hi all,
This is my first post on this forum.
I just finished a Metroamp JTM 45 build, and after solving the "classical" standby switch squeal I'm facing two new issues now:
1) the normal channel sounds AWESOME but the high treble sounds thin, with a lot of background hum and most of all, the channels seems to be "mixed". If I'm connected to the normal, if I raise the volume of the HT one the sound get brighter as if the two channels are jumpered... Is it normal?
2) only one of the speakers output jack works (the one that is far from the impedance switch). The jacks seems go be connected correctly...faulty jack?
Apart from that, the sound of this amplifier is incredible, also the overdrive when cranked up was a surprise to me!
Thanks in advance for your help, this forum rocks!
