This pre has been 90% complete and sitting around for over a year, due to a couple failed attempts at building a power supply from scratch.
The thread that started it all: CLICK
I finally powered it up, and it's not passing a signal. My only clues at this point are a couple of strange voltage readings. -9V at the input of the LT1115. -18V at the output of the LT1010 buffer amp. -18V at the output of the LT1115, which I thought might be normal given that the current source is connected between this point and the -18V rail.
I've carefullly inspected my work for proper connections to each IC pin and for solder bridges, and it looks clean and correct. Any thoughts?
Thanks!
Brian
