Re: Murphy tv19uk10d
The right speaker is / is not affected?
Sound good from left but with buzzing - or no sound only buzzing?
All inputs affected or only certain inputs?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Murphy tv19uk10d
So with only left connected you can ONLY hear buzzing, or you can hear audio + buzzing?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Murphy tv19uk10d
Trying to think of an easy way to test it... You could try hooking up a pair of sensitive headphones (600 ohms or greater) to pin 9 or pin 1 to check the audio signals going into the amplifier. Otherwise, you will need an oscilloscope to test it.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Murphy tv19uk10d
could be a bad dc blocking cap,
but that usually makes these types of amp get VERY hot.
maybe instead of headfones,
you link the left & right inputs on the chip.
if you get noise on both channels it's before the amp.Last edited by stj; 07-01-2014, 05:15 AM.Comment

Hello friends, I just received this equipment, it has a strange hum on the board. The computer works fine, outputs an image and starts Windows. But the problem is when charging the battery, a constant loop to charge. In short, it never charges the battery. When the charger is connected, the stability of the CPU is stressed and it seems that the coils make that electrical sound louder. This board is modern and I don't have a schematic. I have checked with a microscope and the pcb is completely new. Has anyone had this happen to them before? defect in driver ic?...

Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they... -
