This build is much simpler than the blue delay that I have waiting to finish.. but the sound is awesome... just hope that the pt2399 arrive quickly hehe

Pedals are great... but the ones that we build have a complete different taste!!

Merry Christmas to all

nice pedal... and nice clip sound!!!

i see that on the pdf of madbean there is no pcb for etching....

where can i find it man?

feliz natal

Thx guys

yea the tea box enclosure gives a nice look! hhehe

I have an supposable replacement for the oc44 transistor that I will try it. It's a af200 germanium trans as well but instead of 3 pin like this ac128 it as a 4pin for the case itself that as to be grounded... what I think will produce less hi gain noise! Let´s see...

what do you mean by "jack-in-the-box to spring out" ? reverb?
sorry i´m from portugal... Never had problems with the English but some expressions.... 

And what an diy power supply for the pedals?


#290
Ok problem solved!
It was the power transformer that I was using! Crap unit!
Any advice on a diy unit?
I wired it with a battery and... Woooo
Loving  the rangemaster!

just box the rangemaster and at the moment doing some testes with the thunderpuss

final results - rangemaster

Build Reports / first build - RangeMaster

Ok, so i´m proud to share with all of you guys my first Final build (waiting from some components from ebay to finish 3 more  ;D  )

I had  initial problems with a lot of noise coming out from the box but the problem was a crap/cheap power transformer.

Any advice on a nice DIY transf unit?

Change it to battery power and the result was awesome!!!

Combining this pedal to my tubemeister 18 and a marshall cab 2x12" loaded with greenbacks it´s a explosive combination!

Thx Madbean! I love It!!

So after rock it it was time to box it and without the 1590b I improvise and It is the results...

PCB - used magazine paper


the heart ( i wrap the battery and the board with a bubbles bag to avoid any shorts)



and the final results:





after this photos i add a led, at the moment using it without a truebypass but after the new switches arrive i change it.

so hope you enjoy... i´m loving it!

I m using a cheap transf.. I can choose several output voltages... I think range between 3v to 12v

If the pedals are affecting the signal maybe the transf is the source of the noise...

I Will test it with a 9v battery
#293
i think i have the correct wiring, let me explain:
The 9v transformer that i have allow to switch the polarity of the plug
The wiring diagram on the madbean site explains the same way that you tell and for the use of a battery and dc jack it makes all the sense.
Just for testing I´m using the way the photos show:





i can swap the transformer plug so that the center pin becomes the negative/ground

I check it with the DMM and I have 9v (exactly 8,82v) entering the board and no -9v

I follow the wiring instructions for the rangemaster and in that case I have -9v

Am I thinking right?

can the transformer be the cause of the problem?

for the moment i´m using plastic pots... Until the metal ones arrives from ebay (here most of the shops just sells the plastics... )

and the other boards....

the rangemaster ( yesterday I found a shop with a fews ac128)


and the others...
#294
i think its the wiring!

I finish building the rangemaster and it happens the same noise!

the signal gets to the amp but with hum

this is the way i´m wiring just for testing


help please!
#295
Hi

So I ground the jacks and it works.

Is boosting the sound of the guitar but with a lot of noise! something similar to hum
Any ideas?

#296
  ;D Hehe nob stuff!!!  ;D

I was reading the post "how to build and use a basic testing rig" and I saw that ground connection... tomorow before i go to work i will give it a try!

As an off topic:
On the my post "rangemaster oc44 vs af200" that you give some tips I post a question on the wiring of the 4 pin of the tran to ground (the circuit is positive negative and as the 4pin grounds the case of the transistor I don't know if its ok to solder it to ground of the pcb)

Many thanks madbean for sharing and for all the help that you give to all of us

Hi guys

I start building my pedals a week ago...   ::) noob

I´m etching my pcbs, reading some stuff and.... having a lot of fun on doing it! New challenge for the next days... find some oc44 for the rangemaster... hehe

At the moment I have 3 boards waiting for some parts that I order from ebay.

Yesterday I start building the thunderpuss and today wire it up just for test.. simple circuit compare to the blue delay (my first one and still waiting for the pt2399) but I dosent work!  ???

The led is the only think that works... hehhe

I check for bridges, none I can find...

check for the values of the components... everything seem to be ok!

I grounded the input jack to the output but not grounded the jacks to the pcb ground. Is that ok?

I have in parallel 2 resistor in order to achieve the 62k

So... any suggestions?

some photos (without the pot and far far way from my work area that is an authentic mess at this moment  ;D)

Ok md

But This circuit is positive ground... Can i attach it to ground?

hi madben

No. The 4 pin is not connect to the case. the man from the shop told it was the grounding pin for the case.

here is the tran:


i was reading on the web people using the ac128 or the ac188 with nice results but haven't found it either!

thanx

Hi There

I need some help.

I´m starting to build some pedals... by the way I f**** love it  ;D ... for last 5 days start build 4 circuits... but for a noob like me the questions are a lot! Hehehe

Ok, so I have my pcbs, buy the way i´m etching my pcb´s with magazine paper and having nice results, waiting for some IC´s that i bought from ebay and yesterday started on the rangemaster.

On the rangemaster we have the OC44 but here in Lisbon I cant find it, so in that quest I found a shop that sold me an AF200, an transistor that is an replacement for the OC44 (according to a old book that the guy had)

But this transistor as 4 pin... I know that the 4pin is the case ground but...

So, my questions is:

Can I use this AF200? anyone try it? Do I need to change any of the resistor for bias?

What about the 4pin? Cut it off? Solder it?

Thanks
