@JTbbb knowing the other tubes you bought this with, I find it hard to believe this rectifier is a fake. It would seem an odd thing to do to include it with a bunch of other legit tubes. Also, most fake tubes printed lettering is very bold white and perfectly crisp edges. The printing process on...

Beautiful grain and colour 👍🏻

Just to wet the appetite a little. The Aegis + ZMF AC with GEC KT88 - Elrog 274b -RCA Red Base 5691 is something very special. I normally rotate between the AC & Elites every week or so but this setup has been a prolonged rotation.... deadmau5 "while (1<2)" this morning sounds incredible!! Love...

The Atrium Closed are receiving a longer rotation ... tried a few different power tubes with the Elrog 274b & RCA Red Base 5691 but for the AC, the GEC KT88 win every time! I like these tubes for some genres with the Meze Elites but with the higher impedance setting on the Aegis and the AC...

They’re on the list. I was going to buy a backup pair of the EL39s next but maybe these first!! I’d be using them in the Aegis.

I haven’t listened to the KT66 but they get good reviews. They look like June 1964 if that’s VF provided they follow the same pattern as their KT88s

You know, this is what's so great about the Aegis... we can all build an amp that perfectly matches what we want it to look like. For me, it's a testimony how good the Aegis is. I just want to build a chassis that leaves me thinking... job done, forever amp has landed :L3000:

You and me both... I've started on my new chassis. Finished the drawings etc and materials have started coming in... sneak preview below but the final reveal will be when it's finished...probably a month or so away realistically.

MediaLux KT88 review? If so, yes, it was a really good in-depth review of the KT88 tube type. I would love to find that shop in Japan :L3000:

I haven't made that comparison but.... Review and comparison of the KT88 Edit. I found the GEC KT88, as @AnyDave mentioned, has a big big stage with a beautiful airy treble that's smooth as you like. It has an almost spherical 3d feel to the imaging.

If anyone is curious about GEC KT88 date codes. My older pair are SF which = June 1961 and newer ones follow the 8133 I believe 33 is the week number but not 100% sure. I know we don't have 33 months though 😀 Taken from another forum "GEC KT88 Dating. Older tubes, first letter = year and...

From what I read online, the EL38 is derived from EL37 but with a reinforced cathode and screen and was intended for use in TV sets.

Just received my last GEC KT88 backup. Excellent condition, pretty much the same as the other spare but that didn’t have the GEC paper label. My first NOS pair were dated 1980/81 both with black plates but slightly smaller bottle neck on them compared to the 1960/70's backup pair I have. You can...

Beautiful grain pattern on them.... stunning 👍🏻

Very nice, look forward to hearing how they sound! Quite a while back I picked up a pair of NOS RCA 6V6GT Grey Glass. Nice enough..."pleasant sounding" sounds about right. Probably been too spoiled with other offerings :o2smile:

Beautiful 👍🏻

Rawhide… it really brings out the atmosphere of those old western movies or, when listening to Country music!

It becomes smoother over time. It can be a little edgy at first. I found the AC does take a while too settle properly. Improved a lot after 50hrs of use and seemed to stop or only change a little after approx 150.

I love the AC when paired with the GEC KT88… they’ve been running for the last 3 days! As a stroke of luck, I found another near new one to go with my other near new backup. So that should be me done for them now! They’re supposed to last a long time! I’m sure you’ll have many happy hours with...

Black plates, good side getter flash... looking good, are they sounding good?!?

2v is the lowest. Of course you can set the volume at 75% while at 2v. You can change it very easily but my money is on it not really being too critical. You experience an increase in volume basically. No obvious distortion and no additional noise in terms of the noise floor. At 6v the dial is...

It could well be psychological but tonight, and previously I’ve preferred the sound when my DAC/Pre is set higher. Normally 75% and turn the volume up on the Aegis till it’s at a comfortable level. The difference between the 2v and 6v output from the DAC…. So far I’ve preferred 6v… feels very...

So… for those with a preamp with analogue volume control, are you better off turning the volume to max on the preamp or, on the Aegis. Or… does it make no difference in real world sound quality. At the moment I have the VEGA DAC/Preamp set to 75% so I can use the remote and set the volume on...

Ok... I'll keep this in mind when buying the wood... go larger for some spares 🤪😀

My current tube holder means the EL37 remain in my main storage case so the next one will allow for 6 pairs of tubes or a combination of pairs and single rectifiers. I have to admit, I really like having them to hand like this... digging them out of the case which isn't easily accessible is a...
