I had bought one of these a year or so back and had forgotten that I sold it because it had no low end.<br /><br />So I built it again recently with the 470n instead of the 100n and swapped some electrolytics - 47u instead of 22u, 4u7 for the 1u caps and now it has some grunt.<br /><br />So then I built it like that again but with John K's added bass knob, and it sounds great! It even makes a cool overdrive. It surprises me because Bjorn usually has a good ear, but this time he really left out the low end. With John K's help it sounds like it should IMO.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-16615331298991508242016-10-25T22:19:25.802+01:002016-10-25T22:19:25.802+01:00here is a link to the original layout from the ori...here is a link to the original layout from the original poster, but with the copper side flipped horizontally and change of color.

I know the one is a mosfet input but what's the main differences between those opamps and what Audible differences would there be. If much of any.

If you can't get hold of any reverse pot, use a A50K, ground lugs 2 and 3, then link lug 1 where John initially linked lug 3 to the breadboard. It'll then be in counter-clockwise direction but it has no importance at all.<br />And that's it! You'll never get any trebly sound from this attractive DRD. You'll never want to revert to the 3-knob diagram.<br /><br />To be given the choice between two different voltages, more specifically 15 and 5 volts, resort to the 18v/9v charge pump designed by Mark.<br />After the 18v source, solder a 1K0 resistor to get 15 volts. After the 9v source, solder a 2K7 resistor, to retrieve 5 volts. Check out the voltages and adjust the resistor values accordingly.<br />An on-on SPDT toggle switch will enable you to select each voltage. The terminal (Sw2) is to be linked to the vero at the row where the IC pin 7 is located. The 47R resistor is then useless!<br />Frederik Eriksonhttps://www.blogger.com/profile/05133197265918130589noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-60110691253908147742016-02-19T10:17:04.352+00:002016-02-19T10:17:04.352+00:00This comment has been removed by the author.Frederik Eriksonhttps://www.blogger.com/profile/05133197265918130589noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-46876076554311296862016-02-19T10:12:10.227+00:002016-02-19T10:12:10.227+00:00This comment has been removed by the author.Frederik Eriksonhttps://www.blogger.com/profile/05133197265918130589noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-55186851634322649502016-02-16T13:11:17.953+00:002016-02-16T13:11:17.953+00:00This comment has been removed by the author.Frederik Eriksonhttps://www.blogger.com/profile/05133197265918130589noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-87772657263724754192015-12-22T21:30:12.476+00:002015-12-22T21:30:12.476+00:00Mine is also crazy bright
