The TTSH needs  Gate AND Trigger signals with 10/11Volts, otherwise it wont work as designed in usage of the AR/ADSR.


here the simple Solution:

i offer blank and assembled Gateboosters in my shop:

in case of  the version with midi implant connector, run a 1M resistor from ground to Pin3 of TL072 fix the issue.



preferred  Solution:  connect the gatebooster input with a cable from the GATE Input jack from the ttsh. (its needed to cut the trace from the S/H/Gate switch)

 ( ignore the boost trig out pointer on the picture - use the TRIG instead of GND (wink)


for Rev.1 use the speaker holes to mount a bracket

       



for rev.2 and 3:

Install a 3 pinheader in the 6 pol pinholes on bottom of the 2x 1uF electrolyte capacitors in the ADSR section and put the gate booster pcb power input on this 3 pin header.

the pcb sit on top of the IC from the AR section. make sure your gate booster pins don't touch any other parts. if needed install a 10mm or 12mm metalspacer as shown in my picture (on left bottom hole only)




other solution:

drill 2 holes in the pcb and mount brackets with woodscrews,  cut the TIP/HOT traces for 3 jacks on pcb, use one ground (you dont need 3 grounds) run wires from gatebooster to the tip of the jacks

use power from a module section (there are 6 solderholes, 2x3 rows - test with a voltmeter the voltage output/polarity) run powercable to the gatebooster.
