How much did it cost you to make that metal box? Are you going to have the PSU internal? Or are you going to have it external? How are you addressing grounding?

Ill do a starground to an aluminum block or angle aluminum. I work as a fabricator so Im doing this on my lunch break, Im using the remnant metal we have lying around. Its all aluminum, .080" and .125" thick.

PSU, I might use a JLM Powerstation, with a 63va transformer. Most likely external, so Ill have to make another box.

I have about 3 hours invested in it so far. Still going.

Well, 2 of my strips are with Dave Gallo.
He's Doing-
An Eq mod
Changinging some resistors to metal film
fixing the pad circuit
wima caps for the eq
Changing the ICs
and Installing a Jensen JT-110 Transformer

He's basically giving me a template to copy.

Im going to do one more strip with the Jensen and the try Cinemags CMMI-8 tranny.
Dave from cinemag is a very nice fellow, I talked o him on the phone.
He said that The CMMI-8 is they're equivilent to the JT-110.
Really looking forwad to getting this project going!

wow, sounds great.
i would love to see some pictures of the modded channels once they are fnished.

Could you record some before and after audio files...i´d love to hear how the jensen changes the sound.


cheers

I will,

I just finished up the wiring harnes for the power, pots, and ground. Im going to test it out on some stock strips.

The wiring harness wass the hardest part so far.

[The Convicted]

I know there are better ICs out there in soic format but Im trying to fing DIP

Im looking at the opa2134 for the EQs
The fader LME49720

But Im sticking with the opa1611 for the 5534

I might try the opa1642 for the eqs even though its soic

[The Convicted]

Im having a problem with the power supply. Im getting roughly 3 volts on the positive supply, -9volts on the negative supply, the phantom supply is showing something like -69v, and Im also getting a slight voltage on the ground.

I just bought a +-24 v Power One supply HCC24-2.4-A on ebay for $40 bucks and Ill pick one for the +48v from digikey to run this 8 channel project.

What a bummer

Still waiting for some parts to finish this project. But here is the case painted.

If you are doing any diy projects, and dont have the funds to powder coat or anodize.
The Rustolem Hammered finished paint is durable, thick , and easy to apply. Use a good self etching primer before hand.
I had to chemically treat (alodine) the aluminum to etch it for paint adheision.

[Alexi]

wow man, you are extremely talented.
I wish i had your technical skills.

[The Convicted]

Thanx Alexi,
The Guy who taught me is way passed me at work. This is my 11th year of fabricating, and I could always improve. It took a lot of beating on me to get to this point.

Im just about finished with modding the strips. Dave Gallo did alot more to them than I thought, all the way down to severing some traces on the back of the PCB and bridging them else where.

We talked about diiferent ICs, But he uses DIP format ICs instead of the extra cost of soic on adapters.
Not saying his solution is the only one, but it kept the cost down abit, and every one who has a dynamix modded by him seems to really like them.

There were three choices.
1- Jensen JT-110 or JT115 tranny
2- The transformerless card with a video IC
3- High Speed Mic Card

Supprisingly he said only 2 channels of his 24 channel board had transformers, and that he used them mainly for protools playback.
He used his High speed Mic card and the transformerless card for most of his application.
A couple of the electro caps were bridged on the strips.

So 6 of my strips are transformerless card. The other two wil have transformers.
I might go with the Cinemag Cmmi-8 or the Jensen JT-110.

Just ordered 2 Cinemag CMMI-8 Trannys!

Please please PLEASE let me know what you have done and how much (ballpark) it cost, as I am *clueless* when it comes to modding boards, and I have a Dynamix 3000 24:8:1(it was modified to a single stereo main)

I have some modules that were worked on by Jim Williams (there's stickers on it) and I believe Dave Gallo had some work on it as well. Picked it up from Scot Alexander (of Dishwalla). I just don't know where to start. I really need to give this board some TLC. I've had it for about 3 years now, and have recorded one track through it! lol

Feelin' motivated, and I have money to spend. Thanks for any input!

[The Convicted]

Sorry I havent replied, I put the dynamixes to the side, about 100 more bucks and I can finish these.
If you have Dave Gallo modded or Jim williams modded ones, just copy what they did.
I bought two cinemag cmmi-8 trannies but I just have not finished the project yet.
Hopefully soon

Hi... how is teh Dynamix projects ??

Hey "the Convicted"... any chance you could put me in contact with Dave Gallo, I have dynamix 3000 channel strips piled up here and could use a good template channel to re-build my desk. Im thinking to just re-cap and maybe add the newer TLE2072 from texas instruments ( straight swap). However if there is some eq mods ect that make the sweeps and sound more accurate im definately interested...

Just ordered the rest of the resistors and ICs i needed. Maybe another week and a half to finish!
