The Filter knob will not work like this. I ...Hello! The Filter knob will not work like this. I followed up on this subject on a different forum where amateurs like us prefer to use tagboards. Let me share with you my conclusion.<br /><br />1. 2n2 and 22n are misplaced. What is 2n2 above should be the bigger value. and 22 should be the smaller. About the exact value please se the 3rd point.<br /><br />If you execute this change the filter will work somehow, but not exactly as it should. Further modifications can be done.<br /><br />2. Changing the 10k resitor to 100k that comes from the 1uF capacitor to the filter lug 1 and changing the filter pot to 500k (I used B500K, but perhaps A500K is better) will help you further to make it sound good.<br /><br />3. Playing a little with the capacitor values changes the overal sound a lot. 3n9 and 10n is reported to sound like the stock, but I can not affirm this. 10n and 22n is what I used, it sounds lika a Twin.<br /><br />Making these modifications might result in a drop in the overal output volume, but there is still plenty.Sandorhttps://www.blogger.com/profile/00829542408227432135noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-72397713384640590512020-01-28T16:10:21.261-05:002020-01-28T16:10:21.261-05:00hola, me pasó lo mismo, y fue porque puse un conde...hola, me pasó lo mismo, y fue porque puse un condensador de 0,1 uf en vez del de 68nf que está paralelo al diodo, pero lo cambié y quedó bienNicolaspbhttps://www.blogger.com/profile/08571469462716524961noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-73446296394764365162019-06-03T15:08:52.378-04:002019-06-03T15:08:52.378-04:00lo arme tal cual es layout y en mi caso tiene bast...lo arme tal cual es layout y en mi caso tiene bastante MAS ganancia que el original.. en algun lado cometi un error me parece... use J201<br />Anonimohttps://www.blogger.com/profile/01449693118407415948noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-59436784365478196642019-04-09T04:39:47.226-04:002019-04-09T04:39:47.226-04:00A mí tambiénA mí tambiénCharlyMEUhttps://www.blogger.com/profile/07818429158669007310noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-78858525511843099232018-09-23T21:19:24.028-04:002018-09-23T21:19:24.028-04:00The MPF102 might work.
