I love that people here love good music. All the gear lust in the world doesn't equal one aweome album side regardless of the source/amp/cans/speakers/etc.
The amp section is giving me trouble.
I have only tested one amp and it was giving me pretty weird value (I don't remember the exact value now.) The LED off the negative rail is very bright and the negative rail measured something like -0.8V. The LED off the positive rail is very dim and flickers when the amp is powering off. The positive rail measured +30V.
I turned it on once for testing and haven't turned it on since. I figured that whatever is dropping the voltage is getting hot very fast and keep turning it on without knowing the reason isn't a good idea.
I did test the PSU output tho. It gave me the correct +30 and -30 when disconnected from the amp.
Like how I do with other things.... I made a LTSpice model for the amp.... I couldn't get the negative rail to drop like that no matter what I tried... weird... I guess I will have to turn it back on for more measurements now.
I'm praying that the other amp board won't give me any trouble.
