The right channel had the silver+copper wires soldered to the cold(-) and the all-copper wires to the hot(+), which should be the other way around, similar to the left channel. Roy also said the Sonoro was not meant for single ended connections and recommended a rewiring to balanced XLR. Well...

RCA 6SN7GTB January 1976 One of the last tubes made in Harrison, NJ. This would be the same tube your looking at. RCA 6SN7GTB April 1965 This would be the predecessor with full base and earlier advertising. Great sounding GTB tubes. More neutral than you expected of RCA manufacturing.

Just received my Integra cable a few days ago. Visually very nice and premium build quality. Thick silver 18awg and sadly thinner 18awg copper wire. The metal has a quite light colour like in the first picture. Overall a very balanced cable. Sonically it seems to be a great replacement for...

Yes Zach made me an outstanding set of redwood VO. Extra deep red finish with nice burly wood. A masterpiece in my eyes. I didn't expect redwood to sound so different actually. Silk wood might be a great choice if you prefer a smooth and analogue sounding VO. A hard wood will tilt the VO...

Looks like Philips 6v6gt grey glass or could be a 50s RCA 6v6gt. Recently I bought these nice ferranti boxed 6v6gt pair. Made in England is printed. Yea but inside the box is a relabeled RCA vt-107b.

I quoted some impressions about different woods on the VO. I owned 4 different VOs now and found my perfect match. The wood changes the VO quite alot. Hope that helps.

Let me see the top of the tube. Mullard never made 6v6 tubes. They are very likely relabeled. Maybe RCA vt-107a. That's a military printed Brimar 6v6g. Brimar made various different versions over the centuries. You have an early version. That's a British Tungsram 6v6g made in Tottenham...

Finally I grabbed a pair of the famous GEC 6AS7G curved for a reasonable price. Date codes indicate a vintage of 1964. Listening to them today with my pair of GEC AQ2408 1956, a premium quality B65 metal base variant. Absolute linear frequency response from the B65. The 6AS7G add a little...

Can it get much better than this ? Telefunken G73R + Visseaux 6V6GT + Raytheon 22DE4 grey plates. Neutral frequency response, resolving, big staging. That's how I would describe the sound of the Telefunkens. The Visseaux and Raytheon tubes add a sense of Resonance and non fatigue touch to the...

12au7 are unlocked for the Euphoria. Now I can roll my whole 12au7 collection in addition to my 6v6 tubes as driver tubes. So many possibilities it's crazy. This set of tubes has some basic hum just like some 6v6 in adapters can have. Can be different from tube to tube. Some hiss but after...

Sorry this was meant for the Euphoria threat.

Sonically it's sounds warmer than a Raytheon vt231. I think Mullard had a factory in Australia. There is a Mullard labelled 6sn7gta version that was build in Australia. Sadly I can't find a picture of those tubes.

Well I didn't listen to the vt-231 very long. They are so pristine in NIB condition. I'm scared to actually enjoy them 😃 They rival the vt-231 American variants. The staggered plates pair sounds wonderful warm with less resolution than smooth plates. These are quite balanced. I should give...

Oh my pair has support rods also 😲 The early vt-231 version has round mica and unique smooth plates. Unobtanium treasures.

Australian tubes are lovely and quite overlooked by the community. Ah the support rods are used in the 40s version also. Your tubes are labeled as GTA. Never saw that before. The Staggered plates version sounds nicely warm. Earlier version is more balanced.

Did you grab a pair of a 40s AWV vt-231 smooth plates or a nice pair 50s pair with staggered plates ? Westinghouse and Raytheon GTB would be only a side grade. Sylvania GTB is a great performing tube for a fair price. Depends to your budget and your sonical preferences. For sure RCA vt-231...

Solid combination of Sylvania 6sn7gtb 1956 and TS 5998. The prints of the tubes are matching so perfectly that it was worth a picture 📷 No real need for adapter tubes. There are plenty of available native tubes for crazy prices 🤑

Full recommendation for my friend. It's always a pleasure to help you finding the nicest tubes 💡👍

A very nice pair 👍 Looks like 15mm short plates ?

Which kind of Matsushita 12au7 do you have ? They seem to be the only neutral sounding Japanese 12au7 that I found yet. Love these. 1950s, Long plates, 45°D getter

It's a sky effect. Light from the rooftop window reflects like little stars on the dust haha⭐ Lovely, I have many versions of Sylvania 6v6 but never saw this glow. I have blue glow like that with my military GE 6v6gt or RFT 6v6gt.

I think I didn't share a nice tube roll for longer time. I found some really nice and rare American or Japanese variants of 12au7 tubes. Right now I have problems with the treble peak of the Fostex TH900. Some rolls really bring it forward and some cover it completely. This would be a nice...

Did somebody use Ecc33 tubes in the Euphoria? Do they have the same Pinout like ecc32 and can be used without an adapter ?

Why you guys like GE tubes so much ? This 1955 6SN7GTB is pretty okay, better than new production for sure. I didn't like the later versions. Better is the Canadian GE 6SN7GT industrial yellow base with 1950s Sylvania badboy construction: very warm and not the most resolving but sounds great...

That's only the advertising on the tube. I judge them by their inner construction. It's a Tungsol 6as7g. Very nice sounding tube but overpriced.
