    Octanaut not working

    Nope- I was not able to get it to work, assumed I had a bad transformer which i wasn't up to replacing, and shelved it months ago. Thanks for your info! - I will give that a look and report back. If I understand you correctly, you are suggesting a VCC trace between C100 and R10, supposedly...

    Corduroy Fuzz pcb question

    I'm a casual builder with just enough knowledge to get in trouble. Buillding the Corduroy Fuzz and seeing two things on the PCB I haven't noticed before. (1) Why 5 pinout ports for a 3-pin trimmer pot ? 2) What are the little metallic pads that show just above the Q2, Q3, and Q4 transistor...

    Greengage clipping & LEDs issue

    i did continuity testing around the whole clipping circuit, and the switch, and all seemed in order. went from pins 1 and 2 on IC2 down thru R5 and the wiper on the gain pot. no shorting of the leads - snipped em off tight. hmmm. this kinda stuff drives me crazy.

    Greengage clipping & LEDs issue

    Completed a Greengage build and impressed by the gain it puts out. However, I notice no audible clipping regardless of switch position, and the clipping LEDs do not visibly light up. In general. should LEDs be visibly illuminated when they are clipping ? IOW, if they are not visibly lighting...

    Octanaut not working

    thanks for the further tips, eh las bas ma. i confirmed all components, board is clean, and reflowed all pads, still have the bacon-sizzling effect coming out of Transformer 1 and all points down stream of that. Of course I should have socketed the transformers and MOSFETs, but, at this point...

    Octanaut not working

    yes, the signal gets much louder coming OUT of the transformers by turning POT3 and POT6. However, it is still a very degraded, scratchy signal - it gets louder, but the quality remains horrible. (I also get a radio station coming out too - LOL) I tried tweaking all the trimpots, in every...

    Octanaut not working

    well OK, i used my audio probe to step down the signal chain. I have a strong CLEAN signal up to and coming out of the diode set (D1-D4) and INTO Transformer #1. The signal coming OUT of Transformer #1 is weak and very scratchy - "fried egg" sorta stuff. That continues all the way thru Vol1...

    Octanaut not working

    I did check the footswitches - they seemed fine - in one position the top 2 rows show continuity, and in the other position the bottom 2 rows. The jumpers seemed to be doing their job, w/ no shorts. There are no pots underneath the board. In the unboxed situation, pretty sure I had everything...

    Octanaut not working

    Could use another pair of eyes I think. Octanaut produces no sound when footswitch #2 is on. Produces bypass signal when both off, or #1 footswitch on (no difference). I read up on the trimpots... at their "all the way off" position, the drain pin on all four BS170s gets down to about 6.1V -...
