Tube Booster/Overdrive Radio Signal problem

[Zben3129]

Did you ever have it RF free with 9v? If so, are you using the same type of 9v as before (battery/adaptor)?

  Try increasing the value of the cap (330 pF, 470 pF, etc) and see if that helps.

sorry zach, what is RF?

ya i think im gonna try that inscrease the value of it.

thanx guys

Radio frequency/signal

i didnt turn all the way up to see when i fixed put that cap. today i turned up the gain and vol. and realized there was still RF.

so im guessing it was there before too. adn im using same 9v power adaptor.

hmm??

[mitzrecords]

ohh and i also just built fuzz F pedal and it also has a radio signal coming in. so maybe it is my power adaptor??

[mitzrecords]

I used 22AWG wire. Should I use thinner wire for radio signals??

this didn't help. so maybe my power supply?

[mitzrecords]

i guess i might as well try lower value cap from pin 2 to ground.

[mitzrecords]

so i just found this on another thread. i guess i will do this. can't wait!!!
seems pretty simple, just one electro 110uf and regulator?

What you do is just put a 100uF cap across the DC jack (positive leg to positive rail, neg. leg to neg. rail), then, instead of connecting the positive rail directly to the circuit, connect it to the regulator's pin1, ground to pin2, and the circuit to pin3.
Here is the regulator's pinout:


Is this clear?

so today i received 7812 in mail and tried to put it onto my valvecaster. didn't work. I think I'm wiring it wrong. sorry pics are really hard to see. i tired my best.

left: to + of dj jack.
middle:to ground.
right:to 9V board and led.




please help me

Mitz - I don't see a ground connection between your DC socket and the 7812/circuit.

Hi Rick thanx for reply. I put middle one to the input jack shield for ground point.

Is it wrong? sorry im still pretty newbie to this.

any advice would be awesome! thanx!

It looks to me from the photo that the cap is soldered onto the DC socket which is good, but you should also have two wires from the DC socket to the circuit, +ve and ground - you only have one wire from the DC socket to the circuit.

[mitzrecords]

thanx rick. so another one from + on dc jack to ground, is this right?

[Zben3129]

nope, one from - on DC jack to ground on board/input jack/output jack. Pretend that DC jack is actually a battery and battery clip - you don't have the black lead from the battery clip attatched to your circuit.

oh my lord!!

thanx! zach and rick and everyone else! just installed regulator and it fized both hum and radio signal completely!!!

wow!!!

thanks!! sorry for asking step by step im learning lots!!!

thank you!!!

No problemo amigo. Glad you got it working!
