to have, what I believe, are several problems. I'm very confident
the amplifier was in excellent shape when sent as the previous
owner only sold it as he accquired a Lightstar Reference 2.0 amp.
First, the VU meter lights do not illuminate. I removed the cover
and examined the lamps to find one of the blubs has a broken
filament. Okay..no big deal....simple lamp replacements.
I then connected the amp to my C-4000t preamp, TX-12 tuner
and Polk SDA-2B speakers. The amp sounds great, but
demonstrates a few odd characteristics. When powered-on there
is a buzzing sound for about 2 seconds. The left channel seems to
be 5db +/- lower than the right channel. I had to adjust the preamp
balance control at 10:30 - 11 to achieve volume balance.
When powered-down the amp produces a shuttering sound
(Shssss-Thut-tut-tut-tut-tut....tut....tut) starting in the right
channel and migrating to the left channel. Also, when powered-off,
the VU meters jump to a 5-8 watt reading and then slowly (10-15
seconds) dissapate to zero with the right channel meter returning
to zero faster than the left channel.
Are these symptoms normal for a TFM-45?
Can anyone give me a general diagnosis?
I'm concerend that the package had impact during shipping and
the amp needs to vist Rita's repair shop. If so, I would need to
file a damage claim with UPS.
