Question about Teac A-H300 Amplifier
My TEAC Reference 300 amp has developed a problem over the last few months. Currently, only two of the inputs (the Tape I/II) are working correctly. When the CD/Tuner/MD or external sources are connected to any other inputs, I only get sound out of one of my speakers.
Can anyone suggest anything, or should I simply try and find a new amp?
Thanks for your help!
Odd one! Normaly you would loose a channel if the main amp was down, or the pre-amp was. But clearly the main is working. The only conclusion is that there must be more than one pre-amp and that's why the Tape section works. The only way to solve this one is to go inside and trace the imputs to where they join the PC board.
A helpful hint is that if you touch the audio section with a srewdriver, it will buzz! And since you have two channels which copy one another you can work out where the fault is. Because if it buzz's in the good channel, it should in the same place on the bad one.
WARNING don't stick your srewdriver on power parts, and don't short any part out with it.
