Carver CT-23 pre-amplifier/tuner
TFM-15CB power amplifier
I fear one of my two TFM-15CB amplifiers has "died....." Now, when I turn on the tuner/pre-amp and amp units, I get no sound out of my speakers. If I hook up my second amp everything works fine.
For about a month leading up to the failure, I noticed that there was some delay between the time I turned on the rig and the time sound emanated from the speakers. This period increased from about a minute to about 2 hours before total failure.
There is no "pilot error" of which I'm aware. That is, the speaker select button is properly set, the input level knobs are set to maximum, and the unit has power (the power meters light up).
What do you think? Is my amp just dead?
I'm wondering how/why it died. I don't know if others in my house have turned the unit on/off too frequently (I set this up for my mom to listen to, and she is wont to turn the unit off when not actively listening).
Many thanks in advance....
