[QUOTE="DavidC, post: 1170017, member: 21431"] Rehashing an old thread. The Daan Jacobs amps were supplied as a completed PCB, I don't think they were ever sold as a build it yourself module. ( The pre amp on the other hand was only available as a complete built kit with all components supplied) The buyer had the option to buy the enclosure as pictured. Assembly included fitting the heat sink, wiring up the power supply and connecting the input and speaker outputs to the PCB. The reason for the two transformers were that the amp needed -70V-0V- +70v for the 250w version and -50v - 0v - +50 for the 125w version (250w had 4 output transistors and 125 w had 2). Most people used a center tap transformer so only one transformer was required so a 70v-0v-70v AC supply to the rectifier and capacitors in the power supply. With 2 single tap transformers the two would be connected together to get the 70v-0v-70v AC. See images below [/QUOTE]
