Tr%ns*@nt D*s%gn$r PCB, stock or modded?

[quadwould]

the SPL engineers are pretty cool people. i have talked to a couple of them at lenght about their designs and component use for their monitor controllers (both surround and stereo models)

i forget the names of the people, but they were very helpful and excited to talk about their products. so maybe it just that type of company. they know we are a small community, and then even a smaller group within our whole breadth would be innterested in building a "clone".

also i think they are comfortable with their status in the Pro Audio Equipment world and the money they make, and so, do not feel threatened by a few DIYers trying to make their own version of their products.

this is probably also due to the fact that they are a German company run by engineers and not an american Uber-Capitalist company run by Lawyers and Bean counters. Cheers to SPL Labs for helping with corrections :sam: :guinness:

 

[Bauman]

Glad to hear that!!

 

[jhaible]

As I'm the one who published a modified version, I think I should make this clear:

Except for

a) the voltage control and random functions, and
b) the idea of combining a transient designer and noise gate in one unit, sharing a VCA

*everything* in this circuit I have published is either SPL's or Drawmer's intellectual property. My publishing a redrawn version of their original circuits does by no means change anything about this. It is not for me to grant (or deny) permission to build anything from that. If you are in doubt whether providing and pcbs is ok or not, you have to work it out with these manufacturers, not with me.

As for my parts (a and b from above), this is given to the diy community for non-commercial use, like most of my designs. You can freely use this (a, b), as long as you don't make money from it.

JH.

 

[Bauman]

I also wanna say that my intention is to supply you guys some boards for DIY only.
I will stamp on the pcb, top and bottom, NOT FOR COMMERCIAL USE.

cheers!

I've been thinking/stewing over this idea for a few days now...

And I'm not sure if this is a good idea to "clone" the SPL Transient Designer.

If I'm thinking of the right product, I'd suggest that this is very affordable. And it seems that the sentiment here is that this is a good company, so if you're interested in their product, I say buy it, not clone it. I don't know how much money one could save building this, but I generally don't let finances completely dictate what I build.

Something just rubs me the wrong way about this idea :roll: ... :?:

 

[Infernal_Death]

Fabio would it be possible to go with a single sided layout ? So all those guys with etching tanks at home (like me) would have it easier.

[Svart]

I understand that sentiment, but I would still rather DIY my own. I can use any parts I want to use in any way I see fit without having to buy the device and THEN modify it.

besides, it looks to be extremely cheap to build this.

 

[Bauman]

OK guys,

Since this can be seem from lots of angles, like we can check here, I have decided to NOT do this. After felling good/bad/good/bad about it,
it doesnt feel 100% right to do really.

1 - it is a commercial product, still on the stores
2 - not that expensive
3 - the idea of support what you think is a good tool buying it still IS a good idea.
4 - I can use the effort to make something that is public domain and expensive to get from butique manufactures (which S*P*L* dont seem to be...)

So I will abandon this subject.
I love ya all and dont wanna piss anyboby, including the big guys.

hope you understand.
Fabio

 

[clintrubber]

Understood

[smallbutfine]

:sad: :? :grin:
That means we're on the road again hunting for the new fabio special pcb again!
Let's make fun out of it. What was it with the GME-20 melcor? :grin:

 

[Bauman]

Well the ones winning the race are Helios EQ, 553 and la3 and 4.... and slowblow :green:

:guinness:

[kruz]

and the r47!! :wink:

 

[Mlewis]

i think this is a good move actually. i seem to remember stoking the fire excitedly when this was first mentioned but i've changed my angle on this. when it seems likely to be able to buy the product used for as cheap as a swish clone of it i think i'd rather do that and be able to sell it again if i don't use it. Even a new one isn't too expensive. also, since they're so nice to us it'd be a bit rude to clone.

As has already been mentioned it really isn't enough of a mod in my eyes to warant calling it new, it's more like a cut and shut clone of two products.

best left alone me thinks.

thanks to SPL for being so cool about things.

So how about that PRR varimu then?

I´m building it at the moment, and I think it should better be left for P2P. It´s all about different caps, which will have different sizes... My coupling cap(s) will be a combination of oil and polypro - would never fit on a pcb... Don´t want to spoil the fun, just trying to be realistic.
Greg came to the same conclusion, a few postings earlier. Kubi has built it, and said the same.

The designer´s view concerning slowblow and pcb:

[quote author="sismofyt"]bang. pcp suck for tubes. P2P better, more fun and easier to fix
(...) don't bother, with (...) people probably using all kinds of different caps and trannies, it would be pointless [/quote] :roll:

I see this in a different way. I do get your point tho.

Now imagine a guy that never did tube stuff before, how easy can be to have a pcb that
uses easy to get parts with known size, how safe it can be not to deal with high voltage wires all around.... Like, I saw the schemo and it's 10uF and 1uF and we can do it for 1U
like Munlee does with their tube micpre, puting the pcb on vertical.

I have some pcb footprints that I use where you can fit like 10 different types of 10uF caps... from tants to large poliprops...

I agree p2p is more fun for that kinda gear, and I like the looks a lot more (ART!). But if I like this micpre and and to make like 4 to my studio, it's fast as light to stuff 3 more on a pcb, and I can design it in 2/3 hours, along with the R47... :wink:

Maybe I have this kinda point of view cos I am not a tube guy at all, and I like to see just a few wires insde the box. Maybe I am just lazy...So I am still considering doing this :thumb:

Hmmm. I see your point, but you HAVE TO deal with the high voltage when you build a slowblo, because it has big big HV-caps and chokes which you can NOT mount onto a pcb. So I fear a pcb will just give the impression that it is an easy-build (concerning safety), but it is not! I think if you (being a newbie...) are "forced" to do it P2P, you will learn a lot concerning mechanics - mounting parts so that they are fixed securely - and then there might be a bigger chance that the HV-part is done in a neat and safe way. But perhaps I underestimate the skills of newbies (I still consider myself as one :wink.

Maybe I just don´t want to be one of the few who have done all this hard P2P-work, when there is a lazy "shortcut" :grin:

[Greg]

yo Fabio:

You've pretty much totally kicked arse in the preamp department with the API 312, Neve 1272, BA283AV, and the AM stage of the 283. How about adding a nice compressor to your portfolio. And since you're a solid stage guy, how bout the LA-3...

I'm just working you cause I want to build one of those :green: .

But then again, if you don't... then I will... eventually :thumb: .

[khstudio]

For those of you who like the UAD plugins (I do) the SPL Transient Designer will soon be available... check out the demo on the UA site... looks & sounds pretty good.
