We've talked about these old big monsters in the past discussing possible ways to make them a bit more user friendly. I have finally got around to working on it and a lot of my other Kustoms.
Ok she's big Silver/White sparkle 3x15 one of the early A series amps. In and effort to make it lighter I bought some bass lite speakers. Since they are not available in four or sixteen ohms. I got two of them in eight ohm.
The cab is much louder, lighter, and can be moved now. I left the one of the CTS fifteens in the bottom. Not hooked up. First reason is it looks as though the speaker is working and reason two its one heavy speaker that keeps the center of gravity low in the cab. So its not tippy.
The result is lots of volume but also lots of rattles too. So I took the back off and tightned up every bolt in it. Result it still rattles. I like the volume and the portability but these rattles are driving me nuts.
Here's a couple of solutions I have been thinking of and why. I think its not the cab that really rattling but that the bass lites are pushing their reflex air onto the none functioning CTS fifteen and causing these noises.
Solution number one, wire the two ohm bass lites in series making them into a single sixteen ohm speaker as far as the resistance is seeing. Then wiring them in parrelell with the CTS fifteen inch sixteen ohm speaker. This would result in all fifteens workings as and eight ohm cab and also makes the rattles stop.
Solution number two, make a wooden plate that will act as a cover for the CTS fifteen in the bottom of the cab thereby removing the CTS. This keeps the cab's two bass lites in the top working as a four ohm cab. Result no more rattles. I might add a small weight in the bottom of the cab if I do that solution to keep if from rattling.
A some what weirder idea might be to put a sixteen ohm ten in the bottom wiring the entire cab for eight ohms as in the first solution above. Result rattles stop and all speakers work with at least some weight added in the bottom.
Whataya Think Fellas?
