echotodd said:They're VTB1148s wired 1:1. Thanks! I started it a long time ago and kind of got stuck on the options. I'm still mulling over trying Ed's 1166 on the outputs but it sounds so good right now!

I'm using a 1Watt one and still runs hot.
thanks

echotodd said:Check to make sure you don't have any of the pins shorted on the output transistors. That'll make it get hot in a hurry.
echotodd said:warpie,
what are you using for output transistors? Is it happening on one channel or both?
echotodd said:I using the JLM myself. I wanted a dedicated source for my meter lamps so I'm sure you're fine there. Why eliminate the caps at C3&C4? i'm not super great with my electronics know-how but, especially C4 provides an AC ground path for both the MJE2955. My guess is that you have a stability issue that's causing MJE2955 to draw excessive current and looking at the schematic it seems like C4 is a pretty good place to start.
