hello. i recently finished my pimeta and i am having a problem. i tried using the search function, but i couldnt find any answers to my problem. so here it goes. first of all, my amp has 2 buffers per channel, including ground. i havent cased it up yet, but i make sure to isolate the output jack from everything else when i am using it. i measured about 5 mV of offset at each output and i am using 2 9 volt alkalines as my power source. so, my problem is when i am listening to the amp, after a certain amount of time, the sound cuts out and i hear staic, which builds in volume and then everything cuts out and i dont even hear hissing in the background. so i switch it off and turn it back on, and the amount of time it will play before shutting down again seems to correspond to how long i had it on. if i shut it off for a few seconds, it will play for a few seconds then nothing. i have tried both ad8610/8620 and poa 134/2134 and it does it with both. the opamps dont feel hot, and neither does the tle. i didnt check the power rails to the opamps, but i will do that soon. is my amp occilating? i dont know exactly what symptoms of occilation look like, so i dont know.
any and all help will be appreciated.
thanks
