Haha yup
I have some jtune models if ppl interested. That's the limited edition with much higher grounding capacity

I've had the Valvo AZ1 (RGN 1004) and the RGN 2004. Both are gone now but the countdown started lower with both. It also starts lower with the Cossor 53KU (5v) so I have no idea why it does what it does. The good news is that I don't think there are any sonic consequences to a delayed countdown sequence. It seems to be a idiosyncracy of no consequence.Sorry. I have the 1004
I mentioned e83f last week and Xulingmrs has just created a bespoke adapter for those wishing to experiment with this mesh plate telephony tube. I have put my order in but will be away on vacation later this month.

I have installed the small grounding box for the recti adapator. I used the box @plasmod3 recommended. I found a used one online for cheap. It has a very nice effect. It Was not dramatic, more of a refinement. However, i listened to teh same track with it on and off, then attached the grounding wire to the chassis ground on my Shunyata Everest. The little box was the best of the three. All 3 were noticeably different, but not vast. It does what this adaptor does or adds a little more of what this adaptor is doing. If you like the adaptor, you will like the grounding as well. I had a local electrician replace one end of the grounding cable it came with for an alligator clip and just clipped that onto the grounding wire coming from the adaptor.
I was looking at the info I could find online about that box, and it seems it uses alternating layers of dissimilar metals internally. Does anyone know if the designer did anything to avoid galvanic action on those plates?
It seems to me* that could or perhaps even would decrease its effect over time, unless there's something done to block galvanic activity.
* I'm not an engineer. I'm not a scientist. I didn't sleep at a Holiday Inn Express last night, and in fact I'm a bit sleep deprived today. I could be TOTALLY INCORRECT in my ramblings above.
The kojo ground box is quite something indeed
simple but effective and cheap!!! I use them everywhere haha it's easy when you are the distributor
Wow... A treasure trove for sure.Biggest collection of 2504s on the planet? Maybe.... 12 right here and I think I have another one or two in some boxes too
Man, I'd love to have one of those! Maybe one day...Biggest collection of 2504s on the planet? Maybe.... 12 right here and I think I have another one or two in some boxes too
That is quite the trove indeed. BTW: my tube dealer from Verona, Marcos, also has a contact with two Valvo NOS/NIB RGN2504. One box has never been open. But the pricing is stratospheric (1500 Euros/tube). Ian's pricing will likely be more competitive. The quality of Ian's stash looks just as impressive.
I recently bought a Valvo G2004 in sealed box for just eur100. It’s solid plate but ST shape and sounds very good.
Ian has clearly built up some great contacts to procure these rare tubes in such quantities, as they are not something you can just pick up from a quick google.

its quite simple - when a good opportunity comes up just buy the tube haha
it's expensive at the time....almost always is but then having a chance is better than none later on down the track I am never a lucky man to get tubes cheap unfortunately and i know many ppl who feel the same way too

To follow up on my earlier post, both the adapters and e83f tubes have now arrived and I fired them up this morning in place of the RFT 6sn7. I am using some @1960 Valvos with disc getters and the initial impression is of a highly articulate and neutral presentation. Is early days given both valves and adapters are new and need some burn in, however stylistically they are more like sylvania metal plate than rca / mullard and I think will be better matched with a solid plate rectifier than the mesh Valvo I am presently using.
This is a follow-up report on my Takatsuki 274b which I reported an issue with a couple weeks ago.
To my surprise the issue was intermittent after remaining non-operational after many attempts. Prior to shipping back to Alex Sound a couple finger taps on the glass brought it back to life - and it kept working. Over the years I've seen this before with other tubes, but their Lazarus trick would always be short-lived. After review with Alex, we agreed I'd send it in for assessment. They weren't able to recreate an operational issue either. But out of an abundance of caution, they agreed to replace the tube anyway. So a big thank you to Alex Sound and Takatsuki for their support and standing behind their product.
After all this time I never realized I had a magic finger. Could come in handy.

Always great to hear about companies standing by the products and offering good service! A dealer like that can be rare.
In the proverbial “Every time I get out, they pull me back in!” I ordered a 2504 rectifier for an outrageous sum Gotta love Ian! I will let you guys know my findings when it gets here. I also got the new sheath. I am thinking of having my buddy copy it in dense wood, which will look nice and hopefully not be resonant…

Ian was again correct as the Mullard ECC 32 had been dethroned!
I was very fortunate to get the Telefunken CG3s from Ian and theses tubes are incredible.
I am not sure the Horizon can sound any better with the RGN 4 v rectifier and CG3 s and OS1/spf 17c /SRS 551tubes .
