General Questions / Corrugated Boxes
May 12, 2014, 12:07:01 PM
I am trying to find  corrugated boxes for 125B and 195BB enclosures.
Can someone suggest any EU or overseas supplier with low shipping costs?
I ve found smallbear and mammoth but the shipping costs are enormous.

General Questions / panasonic mn3005 vs mn3011
April 15, 2014, 02:06:05 PM
Does anyone know if can we use mn3011 instead of mn3005 or mn3008 for an analog delay?
I just compare their datasheets
mn3005 (4096 stage) has 205ms delay time
mn3008 (2048 stage) has 102.5ms delay time
mn3011 (3328 stage) has 166.4 ms delay time

since mn3011 has longer time than mn3008 why can't we use this one instead of mn3008 ?

Tech Help - Projects Page / Afterlife issues
March 10, 2014, 10:29:25 AM
I just finished afterlife-compressor and on low compression settings I am getting clipped (distorted) signal.
My ic voltages are normal, my Ge diodes are 1n34a with 320mV forward voltage.
Do you think is that normal?
Should I change the sensitivity resistor R7?
Thanx in advance.

I just bought yesterday the Hakko Fx888D soldering station (220V) from the italian distirbutor.

http://www.batterfly.com/shop/hakko_fx-888d

and he gave me a 55 euros discount.
The coupon code is pfx888d
You have to register to apply the coupon.
Hope it helps.
Happy soldering!!!!

Tech Help - Projects Page / Emma Reezafratzitz schematic
February 04, 2014, 09:17:55 AM
I just saw an old built post of Juansolo including Emma Reezafratzitz

http://www.madbeanpedals.com/forum/index.php?topic=12280.0

after a little net searching I found a schematic including bass & mid mod

http://img219.imageshack.us/img219/7998/emmareezafratzitz.jpg

I want to use true by pass switching  so if I omit the C20=150n and the R30=470k everything will be fine?

Also I ve red that this type of distortion makes a lot of noise which comes from the ic, so after an sneak peak on Juansolo built
I found this ebay seller for the 4069 ic.

http://www.ebay.com/itm/300936476763

Do you think will be worth building this one after those minor suggestions?

Does anyone using soldering pot or pool?
Any suggestions on products?
I am thinking buy one to solder wires and small pcbs.

Mods / Uproar baxandall eq
January 07, 2014, 09:05:33 AM
I have built the uproar from the FSB using the MarkGor schematic but I think the frequency response of this dirt box isn't quite good for my taste,
so I was thinking to add an baxandall tone stack.
Do you think if I add the same baxandall eq like (rc-ac booster and bb preamp) after the C4 of the schematic without using the existing tone filter
will make any difference?
Or am I totally wrong?

Tech Help - Projects Page / Aristocrat weird noise
January 06, 2014, 10:47:23 AM
I just finished the Aristocrat and when I engage both channels I noticed a weird high pitch sound.
It appears only when I have both channels on maximum gain and the volume of first channel at 70%.
If I roll back a little volume or any channel gain pot the high pitch disappears.
Does anyone have the same issue?

General Questions / W@pler Pinn@cle switch equivalent
December 24, 2013, 10:19:31 AM
I just found a schematic for Pinnacle
http://www.freestompboxes.org/download/file.php?id=19094&mode=view
but I don't have any on-on DPDT is there a way to use an DPDT on-off?
Also do you think should I add any trimmers to bias betters the jfets?
Thanx for any answers and happy holidays.

General Questions / Harley Benton FXL4
November 15, 2013, 02:18:44 PM
I just saw this cheap looper, do you think that can I do some mods, add klon buffer on every loop or change some components (relays)
to make it worth playing?

General Questions / Clipping options
November 14, 2013, 10:25:20 AM
I am trying to make work a 3way clipping option with an spdt on-off-on,
so I realise that if I want to have 3 different sounds I must omit the LED clipping option, so I have 2 options with cliping and one without clipping
but with a small boost of volume.
Does anyone know a different way to have 3 clipping options using an spdt on-ff-on?

Does anyone know where can I found the taptation chipset?
I try to find it on DIYstompboxes but I believe is currently unavailable.

Tech Help - Projects Page / Serendipity IC issues
October 19, 2013, 06:54:20 PM
I just built Serendipity and when I use OPA2604AP the effect was working but with some fuzziness so
I swap with njm4558D and tlc2272cp and I have no sound.
I measured my ic voltages and everything works fine.
Does anyone experience the same problem?
Do you think I used wrong Ic ?

I just bought from ebay 150 of ac125VI trannies,
I know that are very good for making fuzz but are they good for treble boosters?

Did anyone have the same problem?

Can somenone give me any tips how to desolder easily components on Osh Park pcbs?
I have a desoldering pump but every time its very difficult to desolder on these pcbs,
Do you think a better desoldering pump will make my life easier?
I have this one,
http://www.ebay.com/itm/Industry-Solder-Sucker-Desoldering-Pump-Removal-Vacuum-/200965322230

Everything goes well when I desolder my etched pcbs, I am facing this issue only on Osh park pcbs.
#38
I just finished drawing a schematic using max 1044 for negative power supply.
When I etched it and started step by step to populate it I made some minor changes.
I would like to tell me if those changes are correct.
1) I remove the protection diode and replace it with an 100uF capacitor (datasheet says that it icreases the oscillator frequency).
2)I rotate the polarity of C6 and C7 so negative pin goes to ground.

After those changes I measure voltage on pin 5 -8.92v and on transistor collector -7.3V.
But my issue is that I have hum when I roll up the boost.
Do you believe that hum will disapear if I put it in a box?

#39
I just got from a friend a dead carbon copy, and I believe it's version 2 since it has the diodes near by the transistors.
My main issue is that when I engage the effect I have no delay or modulation, only dry signal appears,
bypass led is on and modulation led is on.
Also I measured ic voltages and the are looking fine.
I checked all over the net and usually carbon copy main issue are Q10, Q11, Q13 and Q14 ( there are j177), they stop working from static electricity.
Can someone post his transistor voltages to compare them with mine.?
