My super thumper has been redesigned once again. The 24 volt AC adapter took 15 seconds to charge the capacitors so I went back to using a power transformer and reduced the charging time to 5 seconds. Note the use of a plastic lid to cover the coil.
Fitting the power transformer in the smaller cabinet was tricky but here it is all fit nicely in the instrument case.
Its up for sale for $250 and I might list one on Ebay to help sell them.
