Even though the entire schematics are out there, the first stage is not correct. Also looks like he lifted the depth and NFB from the BE50 deluxe with some variable cap values. Being that the Brad era Atomica (fine amp) is not a Cameron, but rather Dave's take on the Cameron, this is simply one person's take of another person's take of an amp. Don't expect Cameron tones. This looks like an amp that we'd have to watch the next Jerry Springer show to see who the father is.

Yeah but from the video and from the layout, you can tell it sounds good.

I see a few changes as well. A friend was talking about this and the presence/depth changes are immediate. My Cameron Aldrich has adjustable NFB since the Aldrich can get crazy bright.

I’d love to hear one of these in person. Of course if I owned one, I’d be making sever changes for my personal taste.

Sorry Scott and Dave, but looping at the layout, with the molecular you can have almost exactly the friedman/Cameron atomica even the first stage.... or am i missing à detail?

Yes, the only difference on the first stage that I can see is the use of two trimmers instead of fixed resistors. So you can set those to match the Atomica's values no problem. And the use of a switch for different cap values to bleed some highs. No big deal there. Tone stack uses a 500pF treble cap instead of 470pF. Again no big deal. And then of course the NFB/presence/depth is a bit different but you should be able to get the same sounds, it's just more versatile. Personally, I'd rather use resistors instead of trimmers as nobody is going to open up their amp to mess with those.

I can’t tell from the video. Is he using plugins or IR’s? I don’t see a speaker cabinet or a mic... I’ve found that the IR’s and plugins seem to make everything sound good if you know how to use them.

Thanks, It sounded like a technical point without consequence to me..... thanks for cutting through the bullshit

He states he is using a marshall 1960tv cab, plugged straight into the amp, and a SM 57 to mic the greenback... pretty straight forward

Thanks man!

They even put the dropper they usually omitt...

Great. I missed it.

If you're gonna install iron yourself, you might as well buy it as a kit and just build the entire amp. More fun that way and you learn more in the process.

Agreed
I just wanted to breakdown the argument for ordering the amp without the iron. Even with no amp building experience, they would just need to get a quote from a tech for the $$ to install the iron. The rest of the amp would be done.

The "kit package 1" at $450 USD and 8kg is really good value if you have the skills to build the whole amp from scratch.

It missing the 82k to ground post low input. It should be in parallel to the 1000pf to ground. The voltage divider that is variable is too high used alone. The feel/bleed is also a deviation.

The 82K you're speaking of is just a trim pot instead. Set it to 82K and there you go. And it has a 1000pF in parallel. Doesn't seem like a big deal to me that it's on a switch instead of hardwired.

It's no the same. There are 2 voltage dividers between the stages. The trim pot, is set at 650k. That part is simulating the first gain pot that is usually present in most Jose based amps. So think of that has a hard wire pot. Then there is a second voltage divider with a 68k/68k(1000pf). Simply setting the trim only changes the value of what would be you hard wired pot and then have no subsequent voltage divider.

We just had our ampfest. Here is a quick clippet from my modded Roccaforte. This has basically the Atomica topology

Scott, from equinox schem, 470k//2,2n then 470k to ground. molecular is a trimmer (set at 650K factory) and wired as variable resistance (NOT variable gain). Then the 68K-(Trim//1n) so.... that molecular is easy to tweak tp atomic specs

2 voltage dividers in the Equinox schem

(1) 470k/470k
(2) 68k/82k

In the Ceriation
(1) 470k/650K(trim)

Unless I'm missing something in the layout, there is not another voltage divider before the next stage. Dropping the value of the first voltage divider wont be the same.

 

[nico22]

Scott, first part or the second divider is the 68k to the low input.
Then the second part of that divider is the 1 meg trim//1n cap... it s the feel part of the feel/bleed switch

 

[scottosan]

The 68k to the low input is nothing more than a series resistor, not going to ground. Having an internal trim pot serves little value to most non technical players since they're just likely to screw it up. Just wire in an 82k resistor and stop overcomplicating the circuit. Im simply not a fan of internal trimpots for consumers

There are TWO trim pots. One for each divider. Set the first one to 470K instead of 650K and set the second one to 82K... Are we looking at different schems/layouts or something?
