so if i understand after reading, re-reading, and re-re-reading the application note and using the layout about and the pdf for my pt80 from ggg, it seems as simple as soldering a few connection (after building the board obviously). As for the switches being shown, for the the tempo, pwm, and double time, what switches do you guys recommend? The tempo scale is jsut SPDT switch right? Also, for the delay time pot in the taptation, does that just replace what original time pot from the pt-80?
Only other thing that confuses me is the voltage difference between the two layouts for stripboard and the layout for perf. Why is it only 5vlts for the perf layout and in the stripboard you can use 9vlts? Just wondering
Yes it should be pretty easy to wire in the TapTation into the PT80. You can reuse the 50K linear Delay Time pot for the Time pot on the TapTation if you already have it. The pot doesn't have to be a 100K, just linear taper. If you are going to wire the TapTation via the pads on the GGG board layout then jumper the 1K resistor at T3 otherwise the calibration will be off. Other then that you would just replace the Delay Time pot with the TapTation time control. When you turn the pot it will override the tap time going into manual mode.
The tempo scale switch should be a ON-OFF-ON switch which is a three position SPST switch. If you can't find one you can wire a common ON-ON switch as in the diagram, optionally you can leave the 100K resistor off the center pole in this configuration, and you will get just the quarter and eighth scales. The double time and PWM switches are normal two position SPST switches. The Tempo Input switch can be a toggle or momentary switch, set through the Tempo Clock Pulse Mode Input, but most people with make this a footswitch. You can use the 3PDT that Aron sells using one pole.
If you wish you can skip the voltage regulator and wire into the PT80's 5v supply. The only major caveat is you should be sure how much current you are pulling from the regulator but I think you will be fine. If not or you want to be safe use the regulator provided on the strip board.
