I know. I called them. I alerted them to the interest in the Lampi community and they said they will "consider it". Not sure it will do any good but hopefully somebody can make or identify a better RGN2004 adapter.

What resistor do you use in the adaptor? The one from ebay has 2 1ohm in parallel so .75ohms across wiresYou have right Marty. With the chinese adapter the RGN2004 is just a good tube. The adapter is built with the wrong resistor, which cause extreme heat inside the adapter. Guess what happens with the resistance in this hot enviroment. With the right adapter it is the finest sounding recti I’ve ever heard. I also have a GEC U52, which was one of my favorite recti. In my system I prefer the RGN over the GEC. You should try a Telefunken/Klangfilm RGN2004 with the right adapter

Yup that one used 2 1ohm resisters in parallel so .75ohm effectiveI have no idea what resistors are used in the adapter I bought on ebay.
They probably are not Vishays!1pc Gold plated RGN2004 TO 5Y3 5U4G 5AR4 5Z3P tube converter adapter | eBay

Yup you are right!. I also remembered what I did here as well. I measured the r across the lead rather than desoldering so .75 is correct stillYes someone said the same as well. Let me look up the formula I saw in a textbook. Sounds like I might be wrong..let me check
but 1ohm for each resister is probably wrong. Will have to look into it againAlso photo of adaptor opened up as well

We are working on the Global RGN adapter shortage. Be parient!
Thanks so much to this community. Horizon owners are the best—hands down!! Love all this research and special thanks to Marty for his detailed reports. All of the tube sharing and wisdom around here has improved my system to no end. While I lack the ability to articulate myself and the experience of many here, what I can add to the conversation is that I have found a very clear relationship and “synergy” between tubes which is as important as which tube is in which spot. For example, my ECC32 sounded terrible with the 6384s—so much so that I thought the 32s had a problem. However, the adapted ECC31 sounded great with the 6384. Then, when I got the OS1s, the ECC32s were better by a nice margin. That is the extent of what I have to offer: that the tubes need to have synergy. It is not so simple as choosing a single tube for a slot—one must consider the relationship between all the tubes.
PS I have a well-burnt-in Brimar 5U4G now and have 2 RGN on the way (mesh and non-mesh) with good adapters. I will let you know what I think after they arrive

The OS1 with the RGN 2004/Klangfilm and ECC32 is synergy at its very best in my systemThanks so much to this community. Horizon owners are the best—hands down!!

I am mesmerized watching the Tele RGN do its magic show of color as it powers on
I figured I should folllw the advice of the wizards who turned me on to the OS1 so I ordered two RGN—with and without mesh

Aha! Great photo. In my DIY days, i would have taken this on in a heart beat. I looked at Mouser and there are a number of superb resistors that look like they would work well here. Have fun with it!Yup you are right!. I also remembered what I did here as well. I measured the r across the lead rather than desoldering so .75 is correct still

I’ve also tried the EL51. Very similar sound compared to the OS1. In my system the OS1 was the winner, but I could live easily with the EL51. I might had the wrong EL51, who knows.
Haven’t tried the EL 51 but I am satisfied with the OS1 the 6384 are also spectacular. I have tried lots of recti too: Frankie, Tak, Brimar and Sophia. Soon will try both RGN as well….
I know this is the Horizon thread, but I decided I just had to try the Cosser 53KU staggered plate with my TRP 3. Just ordered one. I’m really starting to gather a full box of rectifiers. For some reason I keep going back to the Sophia Aqua 274b.
