Re: Suhr Reactive Load [schematic]

I built my DIY version. Turned out pretty good. I posted schematic and info here: https://www.freestompboxes.org/viewtopic.php?t=32600 Hi Soulsonic, did you ever find any cause to the distortion? You mentioned the fan or LED as a possible cause of this. I got a used Reactive Load, sounds great, but ...

Re: Dunlop JH-2 FuzzFace modified extra 3 dials. [schematic]

No one has mentioned the fact that isn't the original Dunlop board. Looks like someone gutted a JH-2 and put their own DIY germanium Fuzz Face in it. I mean, this isn't a matter of "someone added some extra controls to a JH-2". This is straight-up not a JH-2. It's a JH-2 box with something else ...

Re: EH - Big Muff Pi ( Ram Head, Early Version )

Now that I've dug this thread back up almost 4 years later, does anyone want me to draw up a schematic of my friend's Big Muff? It's almost like one of the ones on Kit Rae's site, but not exactly.
It's also the best sounding Muff I've ever played through, personally.

Oh yeah! I've swapped wafers and shafts on CTS pots before; they're very modular. That's a good idea!

Re: First Time Member...Help with wiring up a Newmarket Transistor amplifier circuit

I'd like to add that it's wasn't accurate for them to call it a "Deacy" amp. The Deacy amp circuit uses two small transformers: one to drive the push-pull output transistors, and the other is the output transformer. You see this alot in old transistor radios. If I had this, first thing I'd do is ...

I can tell you from experience that you can solder the 880 to the footprint for a SOT-23, but you have to be very careful. Don't sneeze on it. :lol:

Thank you for your work! An early birthday present for me! :D It's exciting to see 2SK880 being used in a commercial guitar pedal. This is the first time I've seen it used in a pedal outside of my own designs. I started using them a few years ago when 2SK117 became impossible to get, and I really ...

Re: Fake 6l6gc's

Yo! I have the "Mullard" version of these! "Factory matched" pair in original boxes. I got them in the late 90's from a hi-fi shop in Chicago I used to work at - they were just hanging out in the stock room and looked pretty old even then. The boss was not a big tube fan, so we didn't really stock ...

Sorry, I had taken these photos back in 2009 when I had worked on one of these to modify it for true bypass. Completely forgot about it.
I didn't take any photos of the board with the controls, sorry. :oops:

Re: Harley Benton - PA100 Power Attenuator [schematic]

Something that I don't like at all in the PA100 and what I don't like is that the volume for the line output is the same as that of the attenuator, that is, the attenuator is at 1 and the line volume potentiometer is at 10. .. listen with very little volume connecting it to a sound card. I mean, I ...

Re: Ammo Can Reactive Load

UPDATE: I found why the transformer was reversing the polarity. The mistake was in the schematic drawing from Edcor. The diagram they provided showed Pin 5 being Hot and in 7 being ground, but it is actually supposed to be the opposite of this. I will update my schematic with the correct pin numbers ...

Re: Cili War Big Muff clone - pedal dies and produces weird static noises

Does it get better or worse if you wiggle the transistors in their sockets? The synth noise when you roll down the drive is going to be some kind of oscillation. Oscillations in high gain pedals are nearly always caused by layout issues. You said it wasn't making that sound when it was outside the ...

Re: Ammo Can Reactive Load

Got to thinking, A good budget approach, or at least easy if you don't want to start from scratch, could be to mod a prebuilt cheap attenuator, like a Harley Benton PA-100, with the reactive parts? But i guess it could be hard to fit? Problem is there's no reactive parts in that thing. The ...

Interesting conversation about the HB Pa 100, I just received one, I opened it, and the first question I ask myself is, is it possible to increase its power, I mean, if now it only supports 100w, ok.
