Radial ProRMP = Jensen Reamp

[Sloan]

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?

 

[Proggm]

Do you know the specs of the transformer?

 

[Sloan]

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

 

[Wolfeman]

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

 

[Soundlurker]

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

 

[deLuther]

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.

Damn, Big Brother was watching! :zombie:

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.
