Is a buffer (EL2001) considered blown if it's spitting out ~7-8V DC from its output?
(I have a bad feeling about this, since the EL2001's seem hard to get now)
Update: Ok, so the buffers don't seem to be blown, since I stuck in a new and untouched EL2001 and got the same result out of that.
Any ideas about this situation: Circuit has correct voltage (18V between rails, with + and - 9V from each rail to ground. Each EL2001 buffer for each channel is outputting ~7-8V DC with nothing at the amp's input. The op amp that outputs to the input of the buffer gets very hot if the buffers are in the circuit, but remains cool if the buffer IC are pulled out of their sockets. Op amp has been replaced with the same result. The only other things in the circuit are resistors, non-polarized (is that the term?) decoupling capacitors, non-polarized input-coupling capacitors, and electrolytic capacitors. The circuit has not been changed and was working before I attempted something yesterday, so there are no shorts.
What could be causing the output DC voltage? What's making the op amp hot when the buffers are in? If a source is connected to the input, all I hear are random pops and random static at the output.
