    Particle Accelerator lack of Bass

    I guys, sorry for my late reply. It was a solder joint.....usual suspects! :) Thanks for your input! Cheers Sono

    Particle Accelerator lack of Bass

    I do have a meter, yes :) I will check the joints, pull out C6, C7, C8, and make sure they are ok and report back. Thanks :)

    Particle Accelerator lack of Bass

    Thanks for your replies. I did check components values and they are ok. I'll try to post pics asap. Cheers Sono

    Particle Accelerator lack of Bass

    Hi. Creach, Thanks for your reply :) The value of the components is Bass A250k, High B250k and Mid I didn't have a 10k so I used a B25k. Do you think that could be the cause? Unless I'm wrong about this, I would've thought that with the bass pot all the way up it should behave like any other...

    Particle Accelerator lack of Bass

    I bought a Particle Accelerator kit from Musikding a while ago and built it. Sounded great with huge bass range. After that I built a clone for a friend and everything seems fine except that it lacks the amount of bass the original has and the bass pot doesn't seem to be doing much. Any ideas as...

    Particle Accelerator - Alembic F-2B clone

    Here goes Nathan :) I've put a 10uF/400v cap as C1 and left R6 as TH to be able to choose the voltage at will (up to 400). In the end I left out the clipping diodes I had added previously. The circuit deals very well with pedals, and saturates nicely and much better than the diodes. Same for...

    Particle Accelerator - Alembic F-2B clone

    This is the schematic with some mods to the original PA: Switch to make it compatible with russian 6NxP tubes and be able to place heaters in series/parallel, Switch to use 12ax7 at 9-12v, 2 options for diode clipping (diodes not specified on schem) and the most important part that needs more...

    Excellent news! Is 125mW enough also for the plate resistors? I will definitely share what I come up with, Nathan. It's the least I can do :) Thanks Sono

    Particle Accelerator - Alembic F-2B clone

    Hi again guys, I would like to ask for some advice on this please: I want to build an SMD version of the PA. The idea is to get JLCPCB to produce the board and assemble the SMD components on it so I can add the TH ones later. I'm going mainly for 0805 resistors but I can't seem to find 1/4w ones...

    Particle Accelerator - Alembic F-2B clone

    Don't get me wrong Nathan, TBH the whole point of my question was "am I being paranoid?". I built this thing and the sound is really great. Through my amp the hiss doesn't bother me, it's kinda "natural" if you will, I mean it doesn't hiss more than the speakers if you know what I mean, and the...

    Particle Accelerator - Alembic F-2B clone

    Ok. I will accept Nathan's answer, although to be honest, I can still hear a difference between bypassed or engaged FX, especially on this audio I posted although Mr. Creach didn't want to listen to it, ignoring what I was saying.: With all due respect, I understand some things need numbers...

    Particle Accelerator - Alembic F-2B clone

    Ok. Please listen to this sample and tell me you don't hear a difference between the first half (before the click) and the second one. If you don't hear a difference I'll just shut up Before the clic the pedal is on bypass... I have tried different valves and different brands (JJ...

    Particle Accelerator - Alembic F-2B clone

    I can hear the hiss perfectly well. Try with headphones. The first bit is the guitar with the FX bypassed, then you will hear a click when the fx is engaged and I can hear clearly a difference. The guitar is not playing at that moment. Maybe I'm exaggerating and the hiss os very faint? Please...

    Particle Accelerator - Alembic F-2B clone

    Here are some audios for you to check this hiss thing. Clips were recorded using a Strat into the pedal, into a line input, a Hi-Z input and a mic input. First bit of playing is always bypassed. Settings are the same on all clips except on one HiZ where I had to adjust the input gain...
