Great !
That's mean I have to debugging mine ^_^

Hi,

I can't see where the SW 1 - 11 goes, I don't find where the OUT is on the layout.
Can you help me figure it out ?

Thanks !!!

Sw1-11 is THE output, so the lead from Sw1-11 goes directly to the output jack

Ok after playing it a bit I could tell it's still not perfect .

I still have noise

when switch 1 is engaged on lugs 1+2/4+5/7+8 (down position for me)

Here's a sample of the noise

Ok I'm not a specialist so maybe I will tell you something wrong ^_^ The "squeal" who was more like an alarm who's screaming like hell, happened when the 7th and 8th lugs were connected So when the 3PDT was on down position. Now I could notice differences in sound on the 3 positions. I sti...

In da box!

I built one couple of months ago
Order a good bunch of trannies, this built is a pain in the ass to bias correctly

You could try with 2N5457, MPF102, J201, J112 but you need to have around 4,5-5v to Q1,3 and 5

If it's your first built maybe it's better to try another one first
If so good luck

Hi guys! I tried to figure out with my squeal problem (I built the first layout from Tagboard Fx) I disconnected the leads 1,4 and 7 to switch 1 one by one to find the bad one. Problem comes from the lead sw1-7, so I connected directly to the BC547 base ans it's working great. But I'm not sure if it...

Hi Optical, Thx for your help, but I'm almost certain it's not a wiring problem I know this kind of problem when in/out leads are too close. In fact It's not really an oscillation, it's more like squeal/buzz, this happened whatever position of the gain pot is, zero to max I didn't box it, I always t...

Thx a lot

Ok I will let it like that, It doesn't bother me how the gain pot works
just curious if it was linked to my switch oscillation problem

So I'm still looking for a solution to this oscillation problem

Any advice?

Hi guys! First thx to Bajaman, Albru80 and all the others who contributed to traced this schematic :thumbsup I built this from Albru80's layout https://nsa39.casimages.com/img/2018/11/29/181129095950157501.png I used BC547 and 2SK117 It sounds great but I still have a problem when Switch 1 OD1 is en...

1N4348 ? Smd SOD-123 size ?
But I didn't find anything

Nice Boby

Smells good I just received my NE570 and LM380 yesterday!
I will try it soon
