Lampizator Valve / Tube Rolling Review Thread

Wow

 

[Golum]

Mamma mia where did you dig those out?!?...amazing...

 

[Zero000]

Found them in my money pocket

The very old man that once owned them says they are unused.

 

[Golum]

They certainly look like that...now i envy you

 

[adamaley]

They sure look like they came right off the factory floor. Congrats on the purchase. Definite keepers regardless of their sound.

Even the bases are solidly fixed on. Loose bases are a real problem on valves this old. Frequently they are re-glued. Sure these haven't been.

I feel a bit happier about using them when the DAC gets back with the Rod Coleman fitted.

FYI https://www.partsconnexion.com/ is having great sale on Takatsuki. I got the rectifier for under $900USD

Good news my Lampizator is finished. I have been told I will be impressed by the lack of hum.

So Lucasz, let's see what putting a competent engineer on my DAC actually results in. A damn site better result than your boys I suspect.

Not a tube question but what type of fuses are people using, fast or slow burn?

Slow

Most gear uses small, slow-blow. Occasionally, I come across something that needs large, but can't recall any fast-blow,. The latter wouldn't be tolerated for long by users. And I can't emphasize enough if SR is used, go up above spec at least 25%. Just had one blow. The Supratek preamp builder had told me 2A was fine back when I made the order, when SR was selling 3-for-2, so I got a 2.5A, although it turns out he supplies 3.15A and says max 4A in the instructions. In any case, the 2.5A was sufficient until yesterday, when I plugged in an extra set of ICs to my subs to burn in the cables ahead of setting up the subs, and started up the preamp. Nothing... That's SR. Audio Magic fuses do run to spec in my experience, as do the HiFi Supreme ones, as I recall.

Do the SR fuses come with any warranty?

Do the SR fuses come with any warranty?

From the SR Orange page: "As always, you are welcome to try Synergistic Research ORANGE Fuses in your system for 30-days risk-free and return them to your SR dealer for a full refund if you are not completely satisfied." Their Red, Black and Blue fuses have similar statements.

Does that cover blown fuses? I'd say definitely yes, if used at spec or even above. If you're not familiar with the sound of the version you're buying, I'd go with a dealer and talk about what happens if a fuse blows. Having done that, I can buy used or new/little used from private parties that don't need what they have.

 

[Zero000]

Asked the engineer who serviced my DAC which of the valves he liked best out of the ones I sent him.

He only had a limited choice. EML Globe Mesh 45, Tung Sol 6A3 and Tesla AD1.

Answer: Tesla AD1. Reason? Plenty of heft at the bottom end.

Another vote for AD1.

...until the beast arrives...

Friday for the DAC but RD will be sooner I think.

 

[wisnon]

Thanks to Goran's source, I will have a pair of the Tesla AD1ns incoming after the Easter break.

I ordered the adapters a week or so ago, so based on Goran's 2.5 month wait, I'll just need to sit tight. Luckily, I have a audiophile server build project that will tide me over. This Lampi GG just keeps asking to be fed the best food possible ;-)

The wait wont be so long. I ordered at same time as Goran and got it 2 -3 weeks earlier. Besides our wait included the China shutdown.

I am scouring the internet for a pair of Tesla RD27AS. Nothing yet. They aren't the most common tube.

No they are not. They are rare.

This seller is OK I have used him.

https://www.ebay.com/itm/114177053074

He only has one at the moment at 75%.

I bought a pair from him at 75% which should be fine. I also have a pair at 100% coming.

I would PM the seller and ask if he expects anymore in.

Thanks.

I did email him but he said that's all he had.
