Parentheses Octave and other issues.

[JetFixxxer]

With Octave engaged I'm not getting the octave. Also if I go full clockwise with the BLEND the output is lower.

Is D6 suppose illuminate?

 

[JetFixxxer]

Also toggle switch in the middle and down sound the same. Toggle switch up sounds different, but volume is low and have to use the boost.

Are your Germanium diodes backward?

Are your Germanium diodes backward?

No, they are opposite polarity.

No, they are opposite polarity.

Ah

Ah

On the Russian diodes the stripe is on the anode (positive) instead of the cathode (negative)

I found D7 and D8 are bad. Not sure why both of those went Tango Uniform.

 

[JetFixxxer]

Anyone have the schematic for this?

Swapped out D7 and D8 and they are still getting blown. I'm getting flow both ways. D4 and D5 are fine.

EDIT: Removed from the PCB they work normal. Place them back into the PCB and signal flows both ways.

I’d stop messing with it until the schematics are available, that way you can really see what’s going on.

I do need to stop messing with it until the schematic is posted. I might have messed the D7 trace up. I also put the "clipping led" as suggested on the other thread. Now when the toggle switch is selected down the volume drops, opposite of what it did. Everything else seems to work except the Octave and not getting the different sounds from two out of the 3 position of the toggle switch. Unless it's subtle..

I do like the sound I'm getting out of it, I wanted the octave portion of it. I have already 4 other fuzz on my pedal.

D7 and D8 are in parallel in opposite polarity so it's normal that they conduct like a diode in both directions.

Might have received a bad batch of 10k resistors. So far 4 of my 10k readings are all over the place.

 

[zgrav]

are you reading them after they have been soldered into your pcb? and are the readings you are getting less than 10K? the other parts on the PCB will often make it impossible to get an accurate reading for your resistance.

 

[JetFixxxer]

The 10k are being read while already soldered. I'm not getting a steady reading. I checked all the other resistors and those are good, when I measured R4 it was all over the place. Checked R8 and R7 with same results. R9 was at 10k and haven't check any others. Will when I get home.

I would just go by the band colors on the resistors you have already put on the board, at least as long as your resistance readings is the same or less than the value shown by the band colors. When you measure on the board you are also getting the resistance on any other paths on the board between those two points so the measured resistance will be lower than shown on the bands. your reading may also vary at first due to capacitors in those other circuit paths.

It varies, but never a constant (even after 2-3 minutes) and it's has only been on the 10k resistors. I'm going check the others that I haven't installed to see. Of course I'm going try to not mess with anything until I get a schematic, it will be difficult as it's in my nature to figure it out.

 

[Nostradoomus]

Desolder one side of the components you want to check...measuring them in circuit will never give you accurate readings
