I'm trying to use 2N2222A BJTs as a toggle switch using the bistable multivibrator circuit connected to JFETs. I based it off of what BOSS uses in their guitar pedals, which is highlighted in the photo. I have 6 of these circuits set up and they are only connected to each other through Vcc and ground. Vcc is around 16V instead of 9V like BOSS does. I have 2 momentary switches hooked up to a rotary switch. The rotary switch is being used as a selector to control which toggle circuits will receive the triggering pulse from each momentary switch. I can only control 2 of the 6 BJT toggle circuits at a time (each connected to one of the momentary switches). However, I'm finding that triggering one of the BJT toggle circuits triggers some of the other ones sometimes even though they're not connected to the momentary switch that was pressed.
So my question is... Why would multiple BJT bistable multivibrators affect each other when hooked up to the same power source, and what can I do to keep them from affecting each other? Most of the collectors of the BJTs go to JFETs, and each multivibrator has an LED attached similar to the BOSS schematic. Most of the values are the same as the BOSS schematic, but the capacitors connected to the collectors are not equal so one side is favored on power up. Also one of the toggle circuits is using 62K resistors because I ran out of 56K. The zener diodes for the LEDs are 9.1V since Vcc is 16V instead of 9V. I thought the circuit would be pretty forgiving with values, so not much calculation went into this. An explanation would be greatly appreciated.
