You're right, I'm missing the 47n before the gain pot.
I'll fix it and upload again.

Fixed, just do a browser refresh.

Ok ! But what's up with r3 or 100k? Cleggy is still keeping it on his schem, but Juansolo said:

The tone pot is really just a treble cut. Pin 3 is not connected. 2 goes via a cap to ground and 1 connects to the output of the circuit and vol pin 3 (output is vol pin 2).

The R3 and R2 resistors mentioned by Cleggy the power feed to the plates. The 23-45v feed goes via them to pin 1 and 6 of the tube socket.

Should I use it or not?

Thanks !!

Perfect ! Thanks a lot !!! I'm ordering the components right now ! ;)

I'm going to build something like a Box of Rock, with the Valvecaster and the Boob Tube ! ... One for slightly overdrive and boost and the second one for something else ;)

EDIT: I have been reading the Cleggy drawn schem, and it's not exactly what Juansolo posted before. There is a 100k (R3) which didn't mention and there is not c2 (47nF) which is supposed to be soldered between tube pin 1 and gain pot pin 3?

Which one is correct? I've drawn exactly the schem with juansolo instruccions also following the pictures (where are 6 caps !) in Cleggy Schem are 5 caps !  ??? ??? ??? ???

Theres a buffer on the output and theres Madbean's Road Rage providing 15v to that, 23v to the plates and 12v to the heaters. It can take a variety of valves, but out of what we had, the NOS Brimar 12BH7 sounded best.


Ok. Let me see... You are using a 12vdc supply which goes into the Road Rage to provide 23v ( or 24?v)... With the Road Rage you are also getting a 15v regulated to supply the buffer, (i've just got a klon so I'm not going to need the buffer, in order i'm not going to use a regulator)

Which IC are you using in the Road Rage for that 12v-23v operation?

Ok I've redrawn the Schem, it is based on your Boob tube pedal !



I think it's allright ! But i've got a few question, which I hope you will be able to answer :)

1.What do you get providing the valve with those 2 different voltages, (appart for the more headroom)?
2.What's the main difference between the Original ValveCaster and your "modded" Valvecaster?
3.What is happening with r3 (100k) and the 3rd lug of the tone Pot?
4.Could I use a non electrolitic 1uF cap to replace c3? Will it improve the tone?
4.Which one do you like best? Original or this? Why?

I'm quite interested in this pedal ! I cannot hear it, but it's really cool !! I'm going to give it a try ! (I'm going to make this one and the original !)

Thanks Juansolo !

Thanks !!  ;D

So, you are powering it with a 9vdc supply and This 9vdc goes into the Road Rage to get those 12vdc, aren't you?

So... If I use a 12vdc source, instead of a 9vdc one... I will power it properly, won't I ?

I do have a 12vdc pin in my power supply with no use...  8) 8) 8)

Ah ! Thanks for those mod tricks ;)

PD - The front design is amazing too  ::) Any audio clips, please?

Awesome !!  :o :o

So you have mixed a Valvecaster with the Klon's buffer, haven't you? ...

What about the power supply? How are you powering this pedal? 9v AC? 12v DC?... Where did you take your layout?

Can you upload the layout you have been using? (i'm an electronic dummie, and I want to do this pedal exactly the way you have done... I'm sure it will sound Impressive)

THanks

That depends on which charge pump you bought.

If you bought a 7660, I believe they will take up to about 13V before they make the magic smoke and die.

But if you got some version of a 1044, you will need a 9.1V Zener, because the 1044 series chips will not tolerate more than 10.2V, per my post above.

And welcome to the forum!




Hi there again ! I'm still in doubt ! I read again the topic and I'm doubting about what CRBMoA said ! Let's begin.

I'm using a 7660 with a 12v zener 1.3w... He said with a 7660 could reach 13v !! So... What kind of zener should I buy (because I cant find those F"@#ing 1n4742? 13v? 14v? Which ones?

Hope you can Help Me ! Thanks a lot ;)

Hi there !!

I started yesterday and I have just finished it. Superb pedal ! I'm going to build another one :) Thanks Brian !

I hope you like it ;)





Sorry for those bad pictures, but It's late in Spain I can't do better ;) Tomorrow I'll do my best to take good ones :)

Hola again :)

Thanks for the advice, Carsten ! They have sold me a 7660SCPAZ with a z at the end, however I haven't heard any high pitch noise. Is this the correct IC? What about the final Z?

I'm loving this pedal !! Incredible !!

Thanks  :D

Hi !! Thanks for answering :)

I received the components this morning, and I have just finished the klon. It's working !!! :):):)

Woaaaoo It sounds like HEAVEN !! Best pedal in my life !!!

I bought a ICL7660SCPA. And I'm using this 12v Zener Diode 1,3w (which don't have any name written in it). By now I'm using a 9v battery and I have been playing for 1 hour with the pedal switch on, but I haven't got any problem !

This diode: http://www.banzaimusic.com/12V-Zener-Diode-1-3W.html ... I'm always buying there, but they don't have the 1n4742. Could you suggest me any substitute? (from banzai)

Will I have a problem powering the pedal with a power plant?

Oh... My Pink Led doesn't bright :( I'm using a DPDT switch very harmed... I think that will be the problem

Thanks Man  ;D ;D ;D ;D ;D

Hi there !

I'm new here ! I'm from Spain and I'm trying to build the sunking ;) ! I bought 1 sunking pcb 2 weeks ago, and now I've got all the components on the table ;) I'm ready to build it !!

But I'm in doubt with one diode. The D3 1n4742 !! I bought the components at BanzaiMusic (germany) and they didn't have this diode. However, I think I bought a similar diode. It's a 12v Zener Diode 1,3w, could I use this one instead of the 1n4742?

I'm waiting for your answers guys !

Thanks a lot ! I love MadBean Projects  ;)
