    Lampizator Valve / Tube Rolling Review Thread

    Follow up on type 27 tubes. I got a pair of inespensive Majestic Mesh type 27 globes that tested good and a pair of adapters. first impression is very positive but I'll post more after I listen more. (so you don't ahve to go looking for it, I'm using them in a SE GG3 with VC). Using the 45...

    Lampizator or PS Audio Directstream DAC Mk2?

    Excellent. I too am enjoying 274B rectification. I have an EML mesh that I really like and an Elrog. I had to build a lampshade for the Elrog because it is so bright but I think it is my favorite and I have the EML in my amp. Enjoy! Jerry

    Lampizator Valve / Tube Rolling Review Thread

    @christoph It is a 2.5V heater like 45 and 2A3. It is rated at a lower heater current. I would think it would be just fine. I didn't know Lampizator had an approved tube list. I didn't get a manual with my Golden Gate 3. Would love to see the list. Jerry

    Any one have experience with Aric Audio?

    @Tuckia I'm sure Aric would be glad to build you a pre with your choice of EMIA in it. He is very accomodating. I've never owned any of his stuff but would by now if I didn't have a custom amp being build. I've chatted with him and he is very open to customization. Jerry

    Lampizator Valve / Tube Rolling Review Thread

    Type 27 tube. I don't recall seeing any discussion of it in this thread. easily adaptable to the 4 pin socket we use, this should work in any DHT Lampizator DAC. Has anyone tried a pair/quad? I tried a pair of 45s and found them ok but nothing special, but they were not a special...

    Lampizator Valve / Tube Rolling Review Thread

    @Gryffles Good to see you proceeding with caution. The Lampizator tube rolling thread is amazing for the variety of tubes that have been swapped in. I recently bought a GG3 single ended. As you point out the current would be higher on a balanced rig. but I think the higher current would most...

    Best Solution to connect for streaming Online music via Qobuz

    I too have spectrum in So Cal. I rplaced the junk modem they provide with a Netgear Nighthawk. I then use Eero Mesh wifi. My ethernet to my audio and HT system comes directly out of my eero hard wired. I have an Ether Regen switch in there before my streamer. I strongly recommend you do as...

    Lampizator Valve / Tube Rolling Review Thread

    Most tubes are lightless of very low light in my amp too. The other tubes are very old 01As that have thoriated tungsten filaments are are very attractive at night. The elrog is the only modern tube (that I know of) using thoriated tungsten filaments but they have overdone it (IMHO). Mesh...

    Lampizator Valve / Tube Rolling Review Thread

    I don't have any of the 4 volters. I'm planning eventually to try one, probably the RGN2004. I think I need to add a dropping resistor to the adapter. I did compare to the EML Mesh 274B which is in the amp in the second photo. I like them both. the adjective that keeps coming to my mind...

    Lampizator Valve / Tube Rolling Review Thread

    New solution to the overbright Elrog 274B. I bought a blue tinted sports bottle and cut the top and bottom off of it and put it over the tube, not dark enough. So I added a layer of red gel filter that I had laying around. Now my listening room is a red light district. the gel filters are...

    Tube rolling mishap with my Lampizator.

    I am a builder like Marco is. I make things and sell them and work on other people's stuff in another hobby. I have a saying, "You only have one reputation." Any time you send out a bad product you degrade your reputation. The worst I've ever done is to forget part of an order. I did one...

    LampizatOr Golden Atlantic + TRP

    I sold my best 6SN7s with a 300b amp but I have a few second tier ones that are still very good. Never tried the Raytheon but it is hard to bea the Sylvania VT-231 and similar. I say similar since anything marked VT-231 is pricey. Jerry

    You guys with the balanced DACs. I have a couple pairs of 6sn7s you could try but no quads. Looking good. Jerry

    Best way to stream Youtube videos to 2 channel system

    Since the sound quality of youtube is generally not that great anyway, I generally either go chromecast to my TV or stream through an hdmi port to my HT reciever. for the latter you'll want a remote keyboard and mouse. For my TV I run a toslink to my DAC and that is my setup for all TV sound...

    Lampizator Valve / Tube Rolling Review Thread

    Golum, I too love the light from a gently glowing tube. The O1As that you expertly identified look great. I know the photo doesn't show it but the bright light from the Elrog swamps them. You can see the shadows on the wall of the 01As. I don't want to hide the elrog, just reduce it...

    Lampizator Valve / Tube Rolling Review Thread

    Thanks guys. I'm thinking maybe a cylinder of filter gel 4" in diamter so it sits away from the tube and held in place by a weighted ring. The faraday cage would probaby not work as the point of light would still shine very bightly through the holes. It would be good to dim a diffuse light...

    Lampizator Valve / Tube Rolling Review Thread

    So I got a couple of modern rectifiers that sound very good. The EML 274B gives a bold full sound with big soundstage. The Elrog 274B seems even bigger but I can't listen to it witout distraction. Maybe it is partly because I wear glasses but it burns so brigthly, even in the daytime, that it...

    Tube rolling mishap with my Lampizator.

    I have a tube tester but I don't usually bother. I've done a lot of tube rolling and very seldom is a tube DOA. I've had a couple of tubes red plate (not immediately) and I caught both before any damage was done. Lastly, bad tubes very seldom damage amps. They can, but it is not very common...

    LampizatOr Golden Atlantic + TRP

    Thanks for the check and sorry I may have hijacked this thread. but I want to edit to make sure there is no incorrect info posted. So the Lampizator DACs are designed for the modern KR 242, correct? I will edit. Turns out I pulled data off a datasheet for a 242A tube, which obviously isn't...

    LampizatOr Golden Atlantic + TRP

    @christoph Thanks for that. Coincindentaly, yesterday I was reading a historical tube data sheet and I saw a comment to the effect that "...the 01A heater can be run at a lower voltage, perhaps 4 V, to extend tube life..." I also was putting together a spreadsheet of parameters for the...

    Lampizator Valve / Tube Rolling Review Thread

    @Zero000 As you say, thoriated tungsten was used as a filament in the 1940s and before. I'm not sure why they stopped. I'd like to know more. Thoriated tungsten is still used widely as an electrode in welding, both machine and manual. many places have banned thoriated tungsten welding...

    LampizatOr Golden Atlantic + TRP

    I've never seen so much eagerness to try new tubes, adapt tubes that don't fit the socket, and discover obscure tubes that I've never heard of. Apparently there has been much success here. I'm currently using a pair of 01As--a tube I had never owned before. Apparently the DAC is much more...

    Tube rolling mishap with my Lampizator.

    Not sure I would send the defective adapter back to the vendor as this is your evidence if you want to try to recover your loss. that said, your loss probably isn't enough to pursue. Thanks for sharing the experience. I damaged an amp using a tube that I thought was an EL84 when instead it...

    Audiophile Fuses

    I didn't realize they use copper melt wire. Copper melts at a much higher temperature so the copper wire fuse will have to get much hotter (approx 2000 deg F for copper vs 500 deg F for normal fuses). This would be a hurdle for the fuse designer but apparently they have gotten over it. I...

    Audiophile Fuses

    @Kingrex I"m a physicist. and I've seen the simplfied explanation you are giving. Not a fan of it. Fuses are neiher copper not silver. They have to be a low melting temp wire with high resistivity, usually a lead/tin allow. I don't know what audiophile fuses use but they have to be...
