Damn Cable is Loose

Not Again So, there you are, a semi-pro or pro musician who owns a PA system. It has worked great for several years.  You start to notice that the speaker cables seem to be loose, or don't connect correctly when you plug them in.  And then, your speakers start to cut out in the middle of a show.   What The Hell Happened?  Several things can cause the problem.  1> a cable goes bad If you are lucky, it is just that the wire has come loose by the connector end, or maybe a wire was broken from repeated yanking of the cable out of the speaker cabinet when you are in rush to pack up and go.  Those are easy and inexpensive repairs to make.  If you are not so lucky, a wire broke somewhere in the cable other than the end, and it is next to impossible to find the exact spot, and if you did, your cable would be too short.  That sucks.  Buy a new cable.  2> a speaker-out jack on the PA head goes out This really sucks.  You might be able to open the PA head up and replace

Mixing Up Speakers

Status Quo I think I have some really great speakers for my guitar amps.  I have a Celestion G12H Anniversary (8ohm), a Celestion Vintage 30 (16 ohm), a WGS HM75 (16 ohm) and a WGS ET65 (8ohm). The Celestion G12H Anniversary has been in my Marshall DSL 15C combo, the WGS ET65 has been in my Marshall DSL 40C combo, and the Celestion Vintage 30 and WGS HM75 have been in a 2x12 cabinet that I used with my HEAT head (a point-to-point hand-wired 50watt head based on a Marshall JCM800 2204). Changes in Amp Preferences A while back, my preferred amp was my Marshall DSL 40C.  Lately,  I've been using the Marshall DSL 15C combo a lot.  After some mods and changes in tube selection, the DSL 15C amp is dialed in.   After I added a post phase inverter volume control the HEAT head and switched to JJ 6V6S power tubes, instead of EL34 power tubes, I have excellent control of volume levels and can drive that amp harder, which delivers clean to crunchy, with a little creaminess all aroun
