Re: help identify symbol on toggle switch

A quick google and... you were right. Jietong. A switch manufacturer.

Doh! I never even considered that, of course.

help identify symbol on toggle switch

Hi. Wiring up my pups in series with a on/off/on switch (like vintage duosonic). Have found a toggle switch that might do the job but am noticing a symbol beside the center lug that I do not recognise.

Can anyone help identify it?

Re: Amptweaker - Tight Metal [traced]

I'm building this up from DimbuGG's 'Tight-Ass' layout on p26.
On the layout there are three blank capacitor slots between pins 1 & 2 on IC2 & 3 and pin 6,7 on IC1. Are these optional slots for small pF capacitors to reduce oscillation/noise?

Re: Triple Wreck boost section issues

I've tested the continuity of both switches and they are working fine.
Can anyone give me more tips to debug this?

Re: Wampler Pedals - Triple Wreck [traced]

Can anyone provide voltages from an original unit, or a clone with the original boost, to assist with debugging?

Triple Wreck boost section issues

Hope someone can help. I've built up a Triple Wreck clone, the pedalparts "Wrecktifier" http://shop.pedalparts.co.uk/Wrecktifier_-_High-Gain_Distortion_with_Boost/p847124_12271789.aspx For the boost section I opted for the original boost as I liked the OD>fuzz sound in demos I'd seen. The ...

I think it's 2N5550 which is NPN with hfe 60-250, making it a good candidate.

Re: Black Arts Toneworks - Pharaoh [traced]

Anyone saw the Supreme version? From their description I'd guess it's a pot (something close to 390k) wired as a variable resistor on the input and that seems like it could be useful. The other control they explain clearly but I find it hard to see the point of having six types of diode available o...

Re: Black Arts Toneworks Black Forest [traced]

There are gut-shots around and they don't look like they've messed with the original values of the Colorsound Overdrive, they've even used the same trannies. This is an educated guess and is not definitive, I've just staggered the input cap values around the original values.

There is no "horus2" layout, the second layout I posted is probably what was being referred to.

I don't recall him ever posting a layout. He posted a schematic he'd drawn. His site has all the schematics for the Vox Starstreamer here http://www.acidfuzz.com/voxguitars
