T Rex Room-Mate [gutshots]

Hello I've got one for repair (reverse polarity incident) so it's not functional, but I thought some gut shot may be interesting :wink: The owner uses this outdoor with a small motorbike battery which is about 6A so the hit was tough, and the pcb has completely fried under a diode (M7 rated to 1A).....

Re: Maestro FSH-1 / Oberheim VCF / Tonepad Filter/Sample/Hol [schematic]

Congrats! seems your build is near perfect 8) In wah mode the attack and release pots have huge influence on the filter sweep range, it's possible to have very good "reverse enveloppe" effects with a some tweaks of those three pots (attack/release/range). The ticking is normal in s/h mode, but it se...

Re: Maestro FSH-1 / Oberheim VCF / Tonepad Filter/Sample/Hol [schematic]

Hi boys. i am taking the plunge once again with this. This time around i will try to build it as per tonepad+grrrrunge specs. Yes because after a couple of day i built mine (see post on page 3) with tonepad-compatible alternatives, while i was fiddling with the multiturn trimmers, something in ther...

Re: Silva mica capacitors

Honestly I'm not sure if someone is really able to hear the difference between silver mica and styroflex or regular poly film caps in most of pedal circuits. However they can be heard easily in microphones as they are sometimes perceived as "hi fi" and better sounding compared to other caps, and tha...

Re: Fuzz Factory first build

Hey welcome! wiring all the grounds to a single point is called "star grounding"; let do a quick search on the forum about the theory :wink: The main idea is to avoid ground loops... and specially for the FF it's really important to pay attention to the ground path. 22AWG wires are really fine, but ...

Re: FuzzFactory upgraded clone problem

I've solved the pop problem! I had to change the bypass switch (got some nice glod plated from Mammoth), cleaned the ground wiring a bit, and I've used the wiring diagram from another layout (which is a bit more simple than the one I've previously used). Now I can hear a pop when the manual/expressi...

Re: Recommendations for budget scope?

On the second hand market you can find nices Hameg 203-7 scopes for less than 50€... sometimes these are even sold with all accessories.
A friend of mine got 20 of them from a school recently for free, so keep an eye open for such good deals.

FuzzFactory upgraded clone problem

Hello I've just build a FF clone using the Madbean schematic (Zombii) with one interesting mod and I have a weird loud pop problem. Yeah it sounds like a "first build" problem, but really it is not the case :wink: The main mod I've added is an expression pedal input to control the Stab, it's wired o...

Re: Zvex - Fuzz Factory [traced]

Hello

have you ever built it with a expression pedal input to control the stab?
I don't know if I should go with a switched jack which will bypass completely the stab pot when plugged, or just add the expression pedal pot in series with the Stab...?

What would you suggest?

Thanks!

Re: DIY power supply issues

I think you've pointed where's the problem; the jack socket sleeve should be always connected to ground so maybe you have not soldered the good pin on your socket (are you using a switched type?). Anyway there is always a small shortcut between V+ and ground when you insert a plug until the plug rea...

Re: DIY power supply issues

On the LM7809 the pin 3 (middle lug) is connected to ground so if yours are correctly wired insulation should not be really necessary... but maybe you could try to let them unconnected to the chassis just to see what happens, then if that works you'll need insulation. Does the problem occurs when yo...

Re: DIY power supply issues

Hi did you use insulation kits for your regulators and are they correctly wired (check the datasheet of the brand you use)? Also you should test continuity with your DMM to be sure that the 9V rails are not connected to the ground (of course you should do that before plugging your laptop psu). The c...

Re: Analog Vocoder Project [verified]

if it's in the same range as the last JH project, your work is really amazing!
But his was a 20 band... and proto pcbs cost 300€.

I'm really impatient to hear something coming from your design.

Re: Barcus Berry 1330 Pre amp Part ID I could use some help

I notice yours has a green stripe rather than a green dot, you think they would use a 700v cap in this ?? Yes that's a bit strange to see that kind of green marking, in fact on mine they seem to have been all green and painted in black only on the ends... they seem to be enclosed in a thick piece o...

It seems to be intented to create a chorus effect when added to a clean signal, so I imagine this works like that: you're playing A 440HZ on your guitar, on its side the +1 oct modulated waveform will oscillate around this frequency above and below few Hertz (don't know how much is the modulation de...

They look a bit different in mine, but I agree with robinbowes they seem to be capacitors.
They remind my some styroflex as you can see here (but value is unreadable):
