I gotta join the Burl club first...Man the connectivity on this thing soooks. I guess it doesn't matter if you're running a full fledged studio, but for my application (small overdub situation), it means I have to have another decent interface. Which means another $2000...I'd have to keep my symphony for enough outs and decent enough DA...or, settle for the Apollo DA and gain it's features going in. (Console, tracking plugs)...I'm gonna have to get a second job - the music industry doesn't pay enough to be a part of the music industry. |

John here's your new Compex if you want it!! I have done a quick search and it seems that there were different models, f760x-rs, f760x-n, and perhaps more. This makes me naturally curious about the differences. Also, there is a lot of talk about recapping. I know that caps can age out. Is this what's happening? Or are boxes like this recapped because "modern" caps are better, built to tighter tolerances, etc? Matt |

Hi Matt,
there are several points to consider when it comes to electrolyte capacitors.
These caps can dry out and lose capacity.
Obviously, this can result in e.g. poor filtering/stabilization when the parts go off spec this way, that the circuit reacts differently as intended.
Also, modern electrolyte caps that are suitable for audio are low-ESR. Generally. Especially compared to caps from the vintage era. Don't know if explanation is needed why low-ESR is 'good'in audio circuits... but it is.
There are also 'solid electrolyte' caps nowadays, that do not dry out.
But recapping can have downsides.
There is a risk the board can be damaged while desoldering and soldering and things can get worse. Often overlooked. Shouldn't happen. But happens from time to time. Depends on pcb type and quality etc...
The low-ESR caps can have a prob with hydrolyse over time, where pressure inside the cap should be reliefed by cracking up the top where you see the cross carves. BUT if the pot does not crack open as it is supposed to - the cap explodes. This can produce a lot of damage in a unit.
And another widely disregarded rule of thumb: "If it's not broken, don't fix it".
Definitely, sound will change in most of the cases. This can be good. But also, it can be undesired. Several gear sounds 'special' due to the parts (brands) used, and even due to the aging and running out of specs. If everybody uses the originals and you recap, chance is high, that your's sounds different, sometimes the caps are part of the 'mojo', sometimes not and they suck and should be replaced. Depends...
In the vintage eras higher tolerances in parts production have mostly been dealt with by the gear builders manual selection (measuring every part by hand...) or designing the circuits to be not picky to work OK...

(Console, tracking plugs)...I'm gonna have to get a second job - the music industry doesn't pay enough to be a part of the music industry. Seeing your problem I can offer some advise since I have all three. IMO the DA on the Symphony is more important than the UAD plugs on the front end of the Burl. It's more of a luxury that I seldom use as I have some nice outboard. And I know you do too. I'd keep the Symphony and pick up a used Burl ADC if I were you. That way you still have the option to expand later with the Symphony which as we all know is plenty pro enough by itself. The Burl is worth it though. If I only used it to catch a buss mix it would be worth it buys also one helluva one shot box. |

I emailed Chad at Vintage King about demoing a B2...Hopefully he won't email back.

Thanks, I appreciate the explanation. I really like the "if it ain't broke, don't fix it" approach. I would hate to alter the tonality of a vintage piece because it's the "in" thing to do. |

Yeah I know a couple techs that are recap happy.
Gotta really monitor what they're doing to your gear

Since were talking caps here, do you guys think that upgraded values make a sonic difference? When I recapped my Ghost I did use upgraded values but I have no way of knowing if it actually made a change for the better or not. From what I've researched, the consensus seems to be that it does help.

I took my CV4 in for a mod, so I'm gonna wait till it gets back to demo the Burl...or when an ass-ton of money comes my way.

Ahh, gear porn, just what I needed. I've heard a little of cowboy's work through the Burl and I'm sold. I'm buying lottery tickets now...

From what I've researched, the consensus seems to be that it does help. I'm not sure what you mean here, you can increase voltage capacity if you piece can "fit" the larger size, but higher values in the audio path start to effect sound by my understanding. I'm no expert by any stretch, but i think any electrolytic in the audio path will benefit from higher quality specs, i use elna silmic ll's in the audio path, and i swear they make a big diff, they just seem smooth to my ears, but i also believe when i beef up a power supply section with great capacitors, it has an effect on the sound for the better, all the other players make things better also, like tight tolerance metal film resistors, and polystyrene caps when ever possible. But like i said, i'm no expert, i'm just an electronics novice, Jeff would be the guy to chime in on this. |

Glad to be aboard Captain J. I do in fact make that Apollo earn its keep, but I fantasize about things like a Burl and a Toft board far too often than I care to admit.
