chuck	help w/ Tone bender MKII..please hi, i built the TBMKII and it works for a few seconds and then the power drops out of it, along w/ the led (used 3pdt). i used 2N388a's transistors and was told to reverse power from - to +, reverse the electolytics on the power supply and drive pot. i did this and checked it, its right. then i decided to change the input electo polarity, which wasn't metioned, this didn't solve the problem, do need to change it back so + is on the input side? does anyone know why the power would drop out like that? i used the stereo input jack for shorting to save batteries, and also wired a power supply jack for optional power. all my other pedals are wired the same and don't have this problem. i appreciate your help on this. chuck
