What do these circled and boxed numbers on a schematic mean?

[guitylerham]

I'm trying to debug a circuit and was curious what these numbers circled in red mean? Are they keys that you reference from the power supply part of the schematic? I imagine they pertain to the voltage reading at that point. All the boxed numbers show voltages, I believe, while the circled numbers do not. There are also keys like "S1" and "E2" or "P2" any idea what these are for?

Are they keys that you reference from the power supply part of the schematic?

Yes the numbers in square boxes all refer to different voltages from the power supply. So all the points with a 5 connect to the 5 you've circled in red on the power supply part of the schematic, all the 1s connect to 1 and so on.
I'm not sure about the numbers in circles, is there any more of the schematic that they could be referring to? Or they could be test points, where you are supposed to measure things.

This schematic actually came from a Korg keyboard. This portion of the schematic is the leslie simulator circuit that has now been isolated and reworked into a standalone pedal. So that may in fact reference another part of the keyboard! Thanks for confirming the voltages aspect.

Good luck with this one! I built it last summer, but never quite got it how I wanted. I've since moved on to other things, but always meant to go back to it. Never enough time...

Oh man, tell me about it! I've got a bunch of issues with this circuit. several transistors aren't reading correctly, one of the MN3007's output sounds super distorted and I can't get any more voltage than 5.5v to it. So far, no leslie effect whatsoever on the output of the circuit, just slightly amplified garbly distorted signal. But I'll do my best to not let this one go. I need to get it up and running for my multi-fx board I'm designing.

Can you tell me what you couldn't get working in your circuit last time?

i had a TINY filament of solder (or some other metal) messing with the power supply to one of the BBDs that caused it to not work. Once I spotted that, it worked, but it's very noisy and missing a ton of top end. Also, I moved the depth trimmer to a pot on the front panel, and I think the LFO signal through the attached wires is giving me some ticking. It needs to be fixed up, but since I made it with the hope of using it in a band that no longer exists, it's sitting pretty far down on my list at the moment. Are you using Bajaman's layout?

[guitylerham]

Hmm, I see. Yeah, I plan to take a toothbrush and scrub the solder side of the board. Do you remember if the MN3007's require a solid 6v at pin 3? I can only get one of them up to 5.5v before the bias trimmer stops. Something else must be wrong.

I am using Bajaman's layout. I included a couple of the tone mods too. I am at a loss right now but I'll keep digging away at it.
