The big question is, any metalwork available for the 500 series PCBs? For most folks, that would be the hardest part of the build, to adapt the PCB to fit correctly.

The first 3 are classics. The Nite is a bit tricky and requires aml pots and some serious bias and adjustments.
That said
Im into the 5003 if its in 500 format.

That was always my question for people who buy pcb and not kits.. do you guys have metal brakes and form and cut your own cases as well, or what? Buying a case is half a build cost from what I've found

Yeah cases aren't cheap. I have a few means. Collective cases has awesome cases; the best imo. Par metal. For me its where there is a will theres a way. It depends on how nice you want it. If your building an aml ez1073 for instance id get the best.

I'm gonna start a separate thread about building cases and sourcing metal in the states. Let me know if you have a BOM or is the pcb labeled clearly? (bom would still be nice)

dandeurloo mentioned before that he could do Nite cases for $150/each if there were 10 orders. I assume he could do other cases too. I'm looking at this Nite eq thread on GDIY and the damn thing is 55 pages. I just want the basic info on these things... BOM Schematic Power Supply Info Case / front panel layout / vendor Total cost.

Having to sift through a bazillion thread pages to figure out how to build the dang thing! What a pita. Why not just include all the important info in the top post or something. I'd love to order the S800 and Nite boards while they're available, but have no idea how much money I'd have to invest or even if I have the ability to get them done. |

Okay the nite is hard. Minus the pots everything is easy to get at mouser. Adjusting the frequencies is a different matter. Unfortunately there was a slight design slip up but can be adjusted.
S800 has a good amount of support and cases are easy. I actually have the front panel file for fpd for whoever needs it.
The green pre has a bagillion threads and is highly documented.
Everything can be run on an antec or lindberg toroidal thats got 15v secondaries.
Psu's can be had from five fish (you can also get a 15v toroidal bundled for about $75 together.For the eq's you vould use mnats (via hairball) for way cheaper and with a toroidal from mouser maybe $35 including components to stuff it.
Damn im practically doing the bom for you.
Jeff probably has a bunch of any hard to get parts for the 5003.

Damn im practically doing the bom for you. Jeff probably has a bunch of any hard to get parts for the 5003. If the Nite is hard, I should avoid that one. The S800 has that parts kit with AML, so that should help. Beyond that, it seems to be power supply, and generic stuff like jacks that I'd still need I guess. This guy slapped his into a pretty rad case with nice chicken knobs and it looks great. diyproaudio.blogspot.com/2013/07/s800-eq-complete-info-to-come-little.html The other option would be to try to fit 4 units into a 2 rack space. Wouldn't look as rad as this, but would have a bit more utility and wouldn't add a ton to the cost if you could get it all into a single case off one power supply. |

That's great diy. I spend a bit on looks. I like fancy knobs. I like push buttons. I like white engraving. Most of all I like it to look professional. Lucky for me I like the igs shadow hills look. Easier to diy. Remember just because it's DIY doesn't mean it's cheap. More than often it actually cost more than the factory made, its just spread out over a longer period of time. Its important to like doing DIY if you're gonna diy. The problems are riddles. Not faults.

So who's down? I think im into a 5003 and maybe 8000.
Also for those interested i have trident and nite eq frontpanel designs.
Also I wanted to say that the nite EQ is super special and anyone that has used it (factory made or this diy version) and so has gotten it to work correctly raves about it. Maag missed the mark ive heard. I know several mastering studios that use the night EQ a lot and love it and swear they could not operate without one. I think dagoose uses one. Stepped pots would make it something else. Its got that air band.

I think I'm going to order boards for 4 channels of S800 and 2 channels of Nite. Even if I can't do the Nite now, I'll at least have boards to give it a go at some point.
I'm curious if the green power can power the s800 or nite.

rocinante, Peter says that The Green PSU will power the S800 or Nites. At least 4 channels of each. Do you think that's my best bet or should I try to figure something else out. I'm a total beginner (other than some basic soldering of kits, Colours and guitar pedals).

The green psu is great. Its a simple hardy design and ive used it in two of my builds. I would definitely reconsider the nite. Just spend two hours on the thread from page 30 to the end. I think you'll then see why.

Yeah there were design mistakes. The repair is replaving resistors eith trimmers and tuning them to get the correct freq then either replace the trimmers with the correct odd resistors or leave them in. The potentiometers for it aint cheap either. A lot of people settled but mind you the plots were off and one wouldn't be boosting or cutting the frequency they thought they were. If the wanted to do it by ear thst would be fine but one could just ignore any front panel because it hardly lined up with what was really happening. Others took the time to do it right and narrowed it down. It took months.
It is so vitally important for me to say that this was a really really hard design to go implement and I don't want anyone to think that the pcbs were bad. They were fine; it's just that it needed far more than the average diyer could do. I have the upmost respect for the designers and think those guys are geniuses. This particular pcb just kind of fell to the wayside and unless one is super patient and has a good understanding of eq plots id leave it alone.

Alright, I'm convinced. I emailed Peter. I'm gonna do 4x S800 and 2x Green PSU. Not sure if I'll do 4 channels in a single case or 2 cases, but we can cross that bridge WAY down the line.
I'm excited. It seems like a good beginner project for a fair price.
Thinking out loud a bit, these eq's are transformerless right? What would it take to add some iron on the output or something? 1:1 can kind of be slapped anywhere right? Would a 1:1 add much in terms of tone?
Also, could I build this green psu in an external case and run power to 2 different units from the single supply? A la Daking.

You wont need to build the psu's in a separate case which is good. Remember a well laid out design is crucial and in the trident and green you have both. I think the motto: "fake it till you make it" applies here.
Copy those before you. Keep the psu in the back near the toroidal and away from the filters and you'll be fine. If you end up doing a rack of tridents (like 6 and up) then id consider it. 1u with 1 psu is pretty standard and might want to be done first.
