  1. Hi I've made a request on some previous post bout chorus-ce1. I don't know if you are interested in this built however i found this board with a modernized version and a schematic https://lectric-fx.com/product/karaoke-chorus-v-1-0/ . Making layouts is way beyond me so please reconsider this if have some spare time on hand.

  2. Volume 1 should be on row I!

    1. Row I. It's currently connected to the filtering cap after Q3 though......

    2. ground=ground, I = ground, so vol1 goes to ground! will try to build it with my last bs170's

    3. Correct, volume 1 is in the wrong row, as is the negative leg of that 100uF cap?

    4. Yup, volume 1 is currently on row H, not I...

    5. negative side of that cap goes to 220cap and 47k res

    7. It does, but as we've said it's also currently got volume 1 going into it as well. Volume 1 needs to be on Row I.

      Far as I can see, that's the only thing wrong with this layout. Move Volume 1 to row I and it's all good.

    1. What transistors are you using? If they had to be flipped I'm assuming they're not BS170s.

    2. the label (s) of the transistors on the layout are correct, the orientation of the transistors should be flipped. i know cause i build this (twice)

    3. yea man they're bs170s unless my eyes have completly degraded ? if thats the case then ive probably brought countless wrong components over time ... just stating what i had to do to fire it up ..... but aside from that amazing tone

  6. Just finished. Sounds Great. Moved Vol 1 down to I. Didn't have to do anything else. Ive been waiting for this one for a while. Thank you.

    1. I'll take look and will probably give it a try. But with 6 op amps it is a biggie for sure...
