I’d be interested in a board and transformers if a small group buy emerges.

#35

I’m currently working on a transformer PCB and 1u module for Intellijel cases. It will allow you to connect the transformers to the rear jacks. Also possible is to leave the 1u module out and connect a Mixup module directly to the transformer PCB.

However this little project is still at an early stage. I’d like to have the boards verified before I have a small run made. Of course all files will be on GitHub. The files should be ready in about a month from now.

I hesitate to repeat Cinemag’s quote on this open forum, but they were responsive and helpful when I emailed them at cinemag@cinemag.biz asking for quote on 2x CM-DBX transformers. I suggest that you also ask about the lead time, since they may not have stock on hand.

Thanks a lot :slight_smile: I understand, I will try to get in touch with them

#38

Wow, thanks a ton for all the responses y’all! Shame that I’m too late for the group buy, oh well. I’ll definitely call them tomorrow and see what’s up. I read in a thread on here that Trent was comparing cinemag and jensen xformers when designing RIP. I’m wondering which Jensen xformer would be the direct analogue to the cinemags used in the stock design. I’m new to circuitry and all that if you cant tell- but yeah i couldnt find any sort of pcb mount 12:1 step down from jensen. Anyone know?

I have been thinking of doing exactly this. Looking forward to seeing what you come up with!

The Jensen clone is JT-DB-EPC. I don’t have numbers to confirm, but I remember them seeming pretty identical in sound / performance way back when (this was 4 years ago).

Thank you so much Trent!!

Figured I would check to see if anyone had a spare pair of CM-DBX transformers lying around before i reach out to the manufacture.

Perhaps a question for general DIY thread but does anyone have any pointers on how to turn the RIP illustrator file into a panel? I’ve done a small amount of research and it seems I need to export to dxf and use Eagle, but it isn’t completely clear to me how to proceed from there… Am I on the right track?

#45

This entirely depends on what company / process you want to use to make the panel. If it’s stamped, machined or lasercut you should just be able to send the ai/pdf file to the fabricator (you probably want to ‘outline text’ in illustrator first).

You’d only want to put it into eagle if you want a PCB front panel. Doing this has become quite popular because small quantities are more accessibly priced, and PCB fabs have tighter tolerances than most metal manufacturers.

Thanks, that clarifies things. I hadn’t realised Eagle was pcb only

#47

I wanted to ask if doing this as diy if:
1- i can use other transformers, and if i should use line matching or input/output ones?
2- is the Ohms value important in relation to the pcb layout or can i use 500 ohms ones?
3- if stereo isnt a needed application, is there a way to route the signal through both transformers (for up/down saturation) or simply using just one?

Thanks!

#48

I really wanted one! but at the moment I am unemployed and broke, so here is my contribution to the project! if anyone wants (I really doubt haha) i can send it in high resolution or vector, i think i have to make some small adjustments in the size. all the best for everyone!

The transformers need to match so they fit into the pcb. I’m not sure about changing ohm values though. I would stick to the original spec which is to bring modular levels down to some sort of line level.

If you only use one input, the signal appears on both outputs. It doesn’t saturate more, just the same on each.

Considering putting mine together finally: Maybe a silly question, but I’m debating what kind of tape to use over the switch contacts. Having seen many kinds of tape at many ages, it’s weirdly less obvious than I would expect! Any recommendations? I lean towards standard electical.

I think I just did two layers of regular ol’ electrical tape. No need to overthink it :wink:

I used blue masking tape - I believe 3M 2” which I believe was purchased around 2009. I find that the tape from this era is more balanced in the low-mids than current production varieties. Gives a nice vintage tape sound.

I used a small piece of Kapton tape.
