There are a couple of minor issues though. The 470uf cap (on the diagram) is spread over 4 holes when it should be only 2.... 13U to 13V. The cut shown at 25E should be at 26E as per the diagram with parts on it. Also, it shows the cuts as 33 x 34... when the norm would be to have it written as 34 x 33.... Though I should have looked before I cut the vero :(. With that it works well and thanks for a great job.Massatonyhttps://www.blogger.com/profile/17811956148443341996noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-34783769645416748602022-09-26T05:46:37.536+01:002022-09-26T05:46:37.536+01:00Having trouble with this one.

I've checked over this thing dozens of time... no micro connections and all component values are as stipulated. I'm getting around 17.8 volts from the charge pump. The only thing I'm not sure of is the lamp. I've just bought a 12 volt lamp from Jaycar and don't know whether the lamp makes any difference.

Everything "works" but it sounds really compressed and distorted. I've knifed it, reflowed solder, checked it a million times, but I still can't figure out where my problem lies. Short of probing the circuit, does anyone have an idea of what might be causing this? It's super frustrating.Mulekickerhttps://www.blogger.com/profile/02560136987462145600noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-67463000109316855202022-04-15T19:40:50.759+01:002022-04-15T19:40:50.759+01:005549 and/or 5539 a mix is also nice.

I realized this by looking at D Means' Neovibe Resley-Tone Tremolo mod scheme. In doing so, the tremolo no longer starts to oscillate. Moreover, lowering the value of the 100K resistance accentuates the tremolo effect. I tested by putting a 50K variable resistor in series with a 47k. At the bottom is the best. I have to test even lower to see. But it's already excellent!francois Junquashttps://www.blogger.com/profile/14562962613142269008noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-1954340314809485202018-04-10T15:27:08.435+01:002018-04-10T15:27:08.435+01:00Just an addition that might help some people :

It has become a bit of an obsession to want to understand more and optimize. After the Banzai LDR + lamp kit, I ordered Photocells Silonex / Advanced Photonix Hi-Dark TO-5 from smallbear and a 7371. It is registered SL-04-17090 1422 on LDR. I took 8 and sorted them.<br /><br />Very beautiful these photocells :))! I have noted a greater progressivity of the incandescence of the 7371. As for the multimeter, the LDRs are also more reactive and have a larger resistance range. The rendering is improved but not as significant proportions as I could have hoped. Which leaves me a little pensive ...<br /><br />By the way, I always fight with the tremolo mode. It has always been a little weak in depth and especially in output volume. I had managed to find a compromise by lowering the value of the 100k resistor in series with the 68nf condo but in the end it was not a panacea either. After changing photocells I tried a return to the values indicated on the Chance diagram. But by doing this I have a saturation oscillation on all the presets. This is where I seek help because I still can not understand the phenomenon. A capacitance story or something? But I do not understand much yet. Do you have prospects?<br /><br />Does your tremolo mode work perfectly? With a signal level similar to chorus and vibrato modes?francois Junquashttps://www.blogger.com/profile/14562962613142269008noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-29406030368865049772018-04-01T14:11:04.890+01:002018-04-01T14:11:04.890+01:00Bye the way, i changed all the phase capacitors to...Bye the way, i changed all the phase capacitors to 10uf (c8,c9,c11,C12,C13,C15,c16 on the harbinger schem) like suggest in the RG report.francois Junquashttps://www.blogger.com/profile/14562962613142269008noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-62993063658623906262018-04-01T12:31:10.633+01:002018-04-01T12:31:10.633+01:00This comment has been removed by the author.francois Junquashttps://www.blogger.com/profile/14562962613142269008noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-12458005871431894832018-02-20T12:06:24.114+00:002018-02-20T12:06:24.114+00:00Found out it was my 18V adaptor 2000ma was far to ...Found out it was my 18V adaptor 2000ma was far to high .That's what I think gave it that strange tweeting sound .
