Larger DC Jack help

Does anyone know where I can find barrel-style negative tip 2.1 DC jacks for a .6 inch / 15mm hole?

Re: Dyna Soar - Lite

I have made some of these in the past and, from what I remember, C9 should be .004uf and the RX is actually a cap and not a resistor. It should be .01uf

Re: you can help to fight the goop - FSB Tracer's Fund

It's still going on, but we're in a bit of a lull at the moment. No particular reason, just lost a little momentum. But feel free to post a new thread with photos when you get the Creamy Dreamer. No need to wait for the Fund to get involved. :thumbsup I am not sure how to get the goop off. It is a ...

Re: you can help to fight the goop - FSB Tracer's Fund

Is the pedal de-gooping still going on?
Someone told me they would send me a Creamy Dreamer to de-goop.

Re: Germanium Transistors

rawr i need some high gain germanium devices so i can build a Hoof Fuzz. I suppose I need to look at Russian? Providing that the transistors show minimum leakage, and a usable gain factor, you should be able to pretty much use any Germanium transistor for a fuzz circuit, I have heard some good thin...

I would love to see pix of that one. You purchased it in '68, or someone else said they did? Post some gut shots if you find it. I'll be going over there in the next few weeks. I'll collect all the old gear and bring it home. As I remember, there are some real gems there! Did you ever find that old...

It is present in alteredsounds version though.

Otherwise, I don't see any differences between the pics and the schem.

Re: Wah sounds octave like and dull

That's weird. You should be able to have a lower value in there. I usually have mine around 300 ohms. DougH has set his as low as 100 ohms IIRC. Lower values sound nice and growly, IMO, good amount of bass and "honk". How does it sound without the buffer? BTW, love your work. I rec' Stomp...

Re: Wah sounds octave like and dull

You've got something wrong with the bias. No worries, it's just a simple resistor swap. My advice: put a 1k trimpot in the Emittor resistor of Q1. It's prolly supposed to be a 470 or 510, something like that... Thanks. I tried that and it did clear up around 1k I might try a really hot HFE transistor

Re: Creamy Dreamer

I believe Jack Orman degooped it but he doesn't have a schematic. He did say that it is different from what people think was done to it.

How about degooping so we can get an accurate schematic of the Sustain Punch Creamy Dreamer?
There's one on Ebay.
