I know this is not a Tascam product but from the same parent company. In the event that you own a X7R or X7 and have had the 2.5 to 3 minute wind time, know that there are people that figure out ways the deck should have been designed in the first place and report it. These people are likely very experienced Technicians or BSEE types. I cover both of those but regardless, the mod I have come up with requires a hook up to the 35 Vdc supply and a small proto board with a couple of transistors and a power resistor as well as two smaller R. My idea is to provide the 26 Vdc to the reel motor supply isolated from the 14Vdc supply by a Diode. This results in a wind only speed change of 3 minutes to less than 1 minute. The motor is marked 24 Vdc so why not deliver some voltage in fast wind mode as is done in the X10R. I suppose I can sell you a kit for this but it is so simple that anyone should be able to hook this in within a 40 minute period. I would have to provide detailed instructions or I could send you a schematic in Pdf format. The mod has been tested in a machine and it works well.
