hi guys, well given up on the rustbucket pcb i acquired, no idea what the problem is with those smoking resistors!
ive built up a harbinger one, and it sounds sweet as. only thing is i feel the top speed is a little slow. found a couple of mods- changing the 4k7 resistors to 2.2k/3k3, and the 2m2 to 5.6m, but the bulb (using an led) stays on. tried switching q11 to a 2n5457 with the pinout switched around, but still no joy, almost seems slightly slower than stock values....?
i understand that there's a point the transistor will stop switching, but still seems a little slow in my mind and compared to some samples ive seen of other univibe effects.
also have a small problem in that if i go all the way slow, then it takes a few seconds when turning the speed back up before it starts oscillating.
any tips of values to trying changing around a bit? few people mentioned playing around with the cap values in the lfo, but i obviously dont want to burn my board out as its the only one ive got!
cheers for any advise!
