2014年11月15日 · A10K = 10K total resistance between the ends, and the resistance is distributed nonlinearly along the rotation. B10K = 10K total, but with the resistance distributed linearly.

2025年2月28日 · Hi everyone, I'm designing a passive switcher to route several inputs (PC output, audio card output, pre-amped record player output) to a set of active speakers.

A10k A100k A250k A500k B1k B5k B25k B100k B1M C500k EDIT: Also, this is for the MOSFET boost if you're ...

2004年7月13日 · Bass - A10K Mid - A10K Treble - B10K Gain - 1M Channel 2 Output - A20K Bass - A10K Mid - A10K Treble - B10K Gain - 500K There is also 5 small 4 legged IC's labeled JTp 37, but I'm having trouble gettin info on these. The parts count is high on this pedal the R and C number are both close to 200 each. There are 3 MC33179D quads and 3 of the duals.

2003年10月18日 · On the alpha pots, "A" is audio taper, and "B" is linear taper. Wish there were more values available in those 16mm audio taper minipots.

2011年10月13日 · If anyone is curious, for the schem. above, dropping the original 100k to ground on the end, and leaving my A10K pot, seemed fine (no surprise). I took off the 51k after the preamp stage and heard no difference, but then I also took off the 1M and heard no difference, so now I have none! (Those would be "pull down resistors" there, correct?

2019年5月23日 · The pots I received with the kit were not all exactly the same as on the board, in the kit there were 1 x A10K (speed), 1 x B10K (depth), 1 x C100K (bias) and 1 x B100K (level). The notes which came with it indicate that C100K should be used for the bias.

2023年11月4日 · A capacitor across R48, the 4.7K feedback resistor, would help tame the highs and also help improve stability.

2017年2月5日 · Hi there! Built yesterday this preamp, using layout from effectslayout blog. Used 2n5457 and BC549. Is the bright and fat switches a big improvment in sound, or just a very subtle effect?

2020年12月21日 · The DRIVE control (replaces SW1, SW2, R19 & R20) is A10K in series with 1.2K. I had also reduced R6 from 4.7K to 240 Ohms in an effort to increase the opto's LED current. Once the opto started working, the effect was extreme gating and a very sputtery sound at lower GAIN settings and/or softer playing.
