This guy sells these SSL clones on Ebay. Are these good components?
"Comes with the "Turbo/Oxford" dual sidechain mod making it far less aggressive, avoiding the overcompression of heavy centre-panned instruments e.g. kick drums. Sidechain is switchable between dual and single sidechains for greater flexibility with different material.
Also uses a custom designed hum-filtering power supply module so there is zero 50Hz hum contaminating the audio signal.
Top quality components throughout, including Panasonic FM low ESR coupling caps, THAT2181 op-amps, Gotham audio hookup cable, Neutrik XLRs and Lorlin rotary switches. No corners cut. These compressors are pretty much indestructible. Some I have built are still going 10 years on.

Should have book-marked it - can't find it now - was a pre built clone - just wondering about the ESR and THAT components listed. Found this though - but it doesn't say what else is needed...French Company Mic and Mod? Not sure if this would be too difficult as a first project? 1176Kit |

I'd get a hairball kit if you really want to make one, or just get a Warm for a little more. |

Thanks svart - I was wondering if it might be a bit ambitious for a first go. I'll see what else comes up.

" <cough> Although it is widely used and ok for this application, to call a Lorlin switch indestructible is what some americans would call an "alternative fact". (sorry, could not resist) A reality fact is that they are very affordable plastic switches that can do their job well but also can break and have to be replaced then. But replacement part then would also be affordable. I think all (?) the units on the market do use them, does anyone know of one using more sturdy switches like expensive Grayhills? Once i broke a Lorlin by accident, probably a weak individual part. But it was easy, very easy. But as i said, they are widely used and the original Gyraf PCBs are designed with these in mind. The other components seem standard parts that do their job and are not cheaper replacements. Panasonic FM are standard, i guess. Panasonic FC was the former "industry standard". I don't know if they are even on the market still, some time there was rumors that Panasonic let them run out to reduce production of through-hole component, but well - just a rumor i read somewhere... The 2181 is the VCA. Standard. Don't even know if there is a cheaper replacement readily available on the market or only available for manufacturers of high count production. These were not what you call inferior. Would have been interesting what Opamps he uses. Most probably the standard TL074 series, otherwise i am pretty sure he had mentioned... |

PS: If the SSL kit is a partial components kit, you have to see, what is needed from the BOM that you might find e.g. on GroupDIY.
The 1176 seems to have all parts but the case, resistors and capacitors, the standard parts. There you can order at a supplier which kind of resistors or caps you want.
The mnats pcbs are good quality design, well documented.
Since you mentioned it: Mic and Mod had some "beef" with the DIY community about how you market stuff with PCBs that other people designed 1:1 without permission...
I guess it has been resolved. But well....
I know of some DIYers that refuse to buy there because of this (not because of kit quality)...
Are these good 1st time DIY projects? Depemds on what you expect. You still have to source some parts, but these are widely available. If you want a "100% guaranteed success paste by numbers all included" project, you will most probably end up with one of Jeff Steigers kits where everything has been chosen with great care and the whole projects are fully documented in the best way possible....

That's all great info. Thanks @smallbutfine. Sounds like one of Jeff's kits is the best place to start.

Pcbgrinder.com does have a gssl kit that Includes everything.... plus there's a build guide.

Oh, did not know Gustav sells full kits. You can bet that they are done with great care. Gustav is always a great person to deal with, he is very dedicated with DIY, his readily built units look gorgeous. Plus he is a great philosopher. (With an academical degree...) I can recommend him just as well. So, it depends what you want to go with. Jeffs API style pre's or a buss compressor. The gyraf SSL is an easy build IMHO and very rewarding. The slightly crowded input section on the pcb is great to develop skills, while still very doable for a first project. Plus - there is more to learn in terms of complexity, understanding VCA compression circuits, opamp input and output section, PSU, and, if you want, upgradable with sidechain filter, turbo board for a second type of compression.... Cost to performance/reward ratio is very good. So if you want an SSL type stereo buss comp, i would say: Go for it - if Gustav supplies a kit i am pretty sure it is great... Thanks, mdmitch2, for chiming in, i wasn't aware of this kit! Considering that Jeff's Pre's are considered probably the finest recreation there are, of course they are great projects, but you started the thread with mentioning the SSL, so i guess you have a demand/good use for it... |

Thanks svart - I was wondering if it might be a bit ambitious for a first go. I'll see what else comes up. I hear the new Hairballs are even easier to build than before.. And they were pretty easy before! |

Thanks for the great input guys. Had a look in the local electrical store yesterday just to see what was available. I'll do a bit of research and gather some tools then have a look at one of these kits.
SSL clone interested me as it wasn't expensive and already built, so I presumed the kits were reasonable. I'd like to go the 500 series direction and so maybe start with a rack?
Thanks again.

Gustav's various kits are top notch. He has the classic gssl but i think his 1176s are dual mono/stereo linked ms. That said its probably a really great piece of hardware. I built his phat phet/fet grinder which is a rev j 1176. Easy as pie. Hairball kits do look easier than ever. Kinda cant go wrong.
