What is the tranny doing sitting at the bottom of the combo cab? Is that a standard configuation or a mod?

Whatever the reason, IMHO It is an " intelligent design " at least for shipping purposes. The chassis on this amp was not built to support the tranny on a long UPS ride across the US. For shipping its best to prop up the tranny with a 2" x 4" cut to size or rewire the amp so the tranny is anchored to the bottom of the cab.

That's the way they were, or at least one version. From a strength standpoint you are right- it is a better place to mount it. However, it was done mainly for other reasons: this location dropped the hum level considerably by putting the magnetic field of the transformer farther away from the preamp and the pickup of the guitar. You'd have to play laying on your back to get the guitar near the transformer!

Another advantage was that the rectifier tube remained base down, as preferred for cooling purposes. Of course, it was also easier to break the tube by throwing gear in the back of the amp.

Mr. Hall, thanks for your insights. They are very much appreciated!
