Hi everyone.
I've built my cmoy!
However, theres a problem - music is quiet through the left headphone and a good level through the right.
I measured the voltage between + and ground and - and ground, and theres a difference. + to ground is around 1.3 volts, while - to ground is around -7.7 volts. Obviously theres a solder bridge somewhere but I can't see/find it!!
The PSU section was completely fine before with 4.5 and -4.5 volts showing for either side of it respectively when tested.
After putting the remainder of the amp if I've got the problem.
I know I can't really get much help with this, and I'll just have to find it, but I need to know if the problem is going to be around the PSU section or wether it could be anywhere?
All the PSU connections look good, and the main op-amp hook up wires (and connections look fine).
Any tips would be great. I've been following Tangent's guide FWIW.
Cheers
