5E3---Pop and I lost my normal channel?

[Memphis.Mike]

I have a Mission 5E3 kit. I was playing tonight...heard a pop and lost my normal channels. Before I start digging can anyone lead me in the right direction? The bright channel is working well. Thanks!

Try another tube in V1 for starters. Check grid wire from inputs to pin 2 of V1. Check voltages at pin 1 & compare to pin 6 (should be about the same). Check integrity of connections of wire from V1 pin 1/coupling cap/wire from coupling cap to Normal vol pot, check pot is working properly. If the rest of the amp works fine, your problem, lies between the Normal volume control & Normal input jacks.
