FlextoneIIuser

I'm not getting any sound from my Flextone II (there is only 1 speaker). It's just a "regular" Flextone II...not an XL, or a Plus, etc. I was playing, and then all of a sudden...no sound. This amp is about 12 years old, used fairly regularly, very good condition, never dropped (lol), never modified/updated in any way, completely "stock". I am getting power It seems to be ok when using the headphone jack....I can hear the differences when I move through amp choices The Line 6 speaker is not blown...(I ran the speaker leads of another small amp to the Line 6 speaker) I didn't notice anything different about the amp prior to losing sound I removed the head from the enclosure and looked at components....didn't see anything broken, no burn marks, etc. I will be checking to see if it might be the speaker/lead wire. Aside from that I don't know what to check. I'd appreciate any troubleshooting tips....things I can look for or test? Are there any "typical" issues, or components that blow out on this particular amp? Thanks Steve
