  1. oh yeah, you can't imagine how anxious i am about finishing it, but you know, everybody always saying to be patient, just didn't want to screw it up XD i'm gonna try now!!!
  2. instead of the 1n4001 diodes for the bridge i used 1n4004, i think this is not a reasson for the higher voltage, but it's after the bridge that i read 17 volts dc although gettig 12.6 ac from the transformer.... please anybody who knows
  3. i'm trying to solve a problem i got now with the power supply now i found my resistor and thought i'd share it here to see if you can help (i'm sure you will ) so, i've wired the power supply of the mc tubes, and i should be getting 15V when there's nothing more plugged in the low dc voltage output, the one to the filaments. but i'm getting no less than 17. i've tried 10ohm 12 ohm and 15 ohm resistors without going under 17, and in the high dc output i should be getting 150 but i got 180, what's the problem, i just wired the power supply as the diagram, if i could get an explanation of what elements i got to change to get the desired voltages it would be great this is the diagram i'm following here

    cd4066

    wow, i've read the sheet. i don't understand a word. haha, see if tomorrow i can get some books and study about this.

    cd4066

    found this sine wave generator, i more or less understand how it works, but could someone help me to move the signal to the levels i need?? i must move the signal so that the lowest level is 0 instead of a negative value to control the 4016 right?

    cd4066

    slowly improving my electronics knowledge i came up with this idea reading your last linl lovecraft: i don't really know if it's already been done if you feed a sine wave to the trigger of the 4016 that should make a tremolo, right? i'm still looking into the sine wave generator, i think it could be done easily with a 555 and then placing an rc on the output, but haven't found a text that explains it yet.
  7. takeshi's castle.... here in spain there were two guys speaking what happened improvising. it was great. i love jackass too, but dude, takeshi's a genius XD

    cd4066

    saber... you are damned right. sorry, i thought i was talking about the 66 when indeed i was thinking of the 53, then it all got mixed in the head..... a look to the specs again was needed. how can all you expirienced people be so patient??

    cd4066

    the series wich i know i can get easily is all that start with 74, so i assume they won't work, i think the high level is 5v. i don't really know if i can get across, but has something to do with the switch, it doesn't matter which pole is the input and wich the output, if you look at the original schematic from geofex you can see they don't u don't need the inverter and in the specs from the 4066 both poles of the switch are mentioned like in/out. that is what i want to do too. but i wanted to have a wide view of all the posibilities. . mmm, that looks interesting, how slowly "slowly" is? enough to having a significant lag as you notice in some digital effects?

    cd4066

    yeah, if you just place the wires in opposite order, you don´t need the not gate. what about the d-flip flop can i just use any?? the signal level is always the same isn't it?
  11. all you have to do is desolder the wires that go from the pickup to the pots and wire the new ones instead. there should be no problem if they have the same number of wires, in case the number was different, and you wanted to go for something a little bit more complicated as coil phase reversal.... check out the tutorial pages, tutorials or go to guitarElectronicsto the wiring diagrams section and have a look

    cd4066

    indeed i was thinking of using q to control both, what may be the difference?

    cd4066

    ok, i've been reading the article on geofex to make a bypass with a cd4053, but ansil recomended using cd4066. can i just replace it directly, i mean, minding the differences in pin layouts. about the flip flop. can i replace it with just any d flip flop. las question, why not use the last switch to control the led?? here's the link to the geofex
  14. love the shape, i don't see anything wrong with the headstock, but go for something crazy really love that body.

    varitone

    i think he means something like this the image, btw

    Mid Freqs

    maybe this is just a total misunderstanding of effects loops, but here i go: if you place an eq in the effects loop and try to overdrive the power amp, could you be just overdriving the input on the eq, i mean if the eq is made with opamps or whatever, you are overdriving that instead of the valves in the power amp. is this right? maybe you meant a passive and not a pedal there? this really interests me, cos i'm planning on building a preamp, and maybe it would be a good idea to have two or more eq in different stages.
  17. well, don't really need to perform that well if the look really good
  18. works great with that program . not so nice looking as electronics workbench tho
  19. no way to make it work i'm using electronics workbench multisim 7, any chances it could be the software. i would use spice, but i really don't know how to make it work
  20. a quick search got this, it's just for the last 30 days, i remember reading a lot more about this topic, even a tutorial de que parte de españa eres??
  21. nope, i've tried it, the same problem, the reading in b is about half the reading in a. doesn't make sense to me. any other ideas?? edit: in the schematic i was trying to imitate it said +150V to that point, that is why i placed it like that.
  22. could anyone try the circuit in the link in the simulation software he uses and feedback what he sees in the osciloscope. i swear the output signal is smaller than the input signal, shouldn't it be the opposite or just look at the schematic and tell me where i've screwed up
