Hi I´m building the ultra flanger from the layout at geofex http://www.geofex.com/pcb_layouts/layouts/ultrafln.pdf
According to the parts list r24 is 2.7k, but it also says 39k, further down. There is no resistor value value for r25.
Am I missing something? which one is supposed to be 39k.
Best Regards

When I built this I asked the same question and was advised by oldrocker that R24 is 39K and R25 is 2.7K.
Beware on this build as from what I understand a number of people (myself included) can't seem to get rid of the ticking. For my abilities this was a build above my understanding but I needed a flanger so dived in, but others seem to have had a similar problem. If you can get it to work without the ticking it is an incredibly cool flanger.

The problem is that RG inadvertently had R24 twice on his list of components in that documents. As you work your way down the component list, you'll see that the first time R24 is mentioned (2k7), it should actually say R25. The second time it is mentioned (39k), it is accurate.
Thanks very much. I will report back when I´m finished, to let you know if it´s ticking or not.
Hmm. voltages seems ok, and controls are working. But no guitar signal coming thru. When turning the manual knob, the signal comes thru, but the effect dissapears. Time to debug.
