Sharing in the event someone finds value...

I have a TFTC in which the right channel - after playing for a bit - would simply go quiet...was certain it was the sound board, and if not the Z-connector - or possibly the connector at the sound board (all of which I explored) - but a friend of mine suggested the speaker itself - I thought, nah... Turns out - the voice-coil would slowly heat up and the impedance would rise (up to 66 ohms) and thus squelch the channel...turn the pin off for a bit - it'd start out at 4 ohms and slowly rise to 66 ohms again....sure as heck I thought I guess a good time to upgrade the backbox speakers anyway - I did - and all is good again in the right channel. Never would have thunk that....

It sure is nice when it's something easy like that! And an upgrade, all good.

I’m thinking that it was not so easy. When we have sound issues we are from experience, always checking boards, connectors, misc stuff. Rarely do we look at the speaker and hence why this may not be so easy simply as the speaker is often times assumed to be fine. “What can go wrong with a speaker right?”…
