    So, I gave in and ordered a Radial ProRMP. Immediately, I dissasembled the bastard to see what it was made of. Pretty much exactly the same as the Jensen reamp other than three extra resistors. Wow. Shit cost me $100.

    I lost my internet connection, so I don't have all my gut shots (the construction is good), but here is a circuit diagram I drew up and an image of the jensen schematic. You can see the similarites.

    What's the Jensen reamp? Is that from one of the more popular DIY schems?

    Do you know the specs of the transformer?

    not sure on the transformer specs. there's a spec sheet for the jensen online.

    That's because Radial bought a license from Jensen, hence why its practically identical. There are a few others out there also.

    Buy an active DI and post a schematic also :loco:

    The quality of the transformer is what counts, I think.

    How much additional resistors can affect output level (compared to Jensen`s schematics)?

    Please gutshots!

    The Radial J48 looks also very easy to replicate (if some-one would make a lot of pictures of it):

    I took apart my Redeye and posted schematics of it on another forum, and within 2 days I got a cease and desist notification. Just be cautious when you guys post stuff like this.

    Interesting it seems that new version of J48 can have some differences (from Radial site), old picture, like on Thomann also available on old site.
