You can e-mail
[email protected] and we can send you some additional LED's.
I would encourage you, however, to post all your resistances before turning this amp on again.
If the resistance check is good, then move on to powering up the amp.
For an issue like an LED not lighting, that is certainly what we are here for. More often than not, this actually has nothing to do with the LED itself, but manifests from elsewhere in the circuit.
