at the risk of being redundant, is the electro on the LP input
alligned correctly?
also did you use the same transistors specified in the schematic?
metal cans or TO92s? its worth double checking you haven't got the
pinouts mixed, there is a lot of variation between different makes.
check the datasheets for the ones you are using.
its a common mistake - especially for me
