For this price it's a no-brainer!

Advantages: Very strong suction, easy to clean. Cheap!

Disadvantages: Very big and everything except the springs is made out of plastic.

Wow, for the price, these are unbeatable.
they work really well in my 10 year old Copland CTA-402 Amplifier

Advantages: Once 'broken in' (about 50 hours), the sound these produce is wonderful. Where they really excel is in the pace and rhythm they give and a lovely air to the cymbals on everything I've listened to. The BIAS settings are rock solid with less then 1ma of drift when fully warmed up.

Disadvantages: none at all

Spaßmacher pur, bringt leben ins Klangbild, Blechbläser und Stimmenwerden sehr natürlich wiedergegeben. Die räumliche Abbildung ist sehr gut. Einsatz von 4 Stck im Eingang der VT 200 von Audio Research 6 Stck EH als Treiber und in der Verstärkung 6550 Tung Sol ein wirklich gelungen Kombination.

Advantages: Gegenüber Sovotek, Philips und EH
Diese Röhren haben eine Räumlichkeit und eine Tiefe die andere Röhren nicht haben. Die Leichtigkeit wie diese Glühwürmer spielen ist einfach klasse. Sehr natürlich im Mitteltonbereich sanft in den höhen, nicht ganz so straff im Tiefbassbereich wie eine Philips aber das macht ein geschlossenes System beim Lautsprecher wett.

Disadvantages: geht nicht ganz so tief in den Keller und wirkt leicht aufgedickt ist aber in den meisten Fällen zu vernachlässigen.

Great!

I received mine quad today and I first was suprised tubes are double marked =C= and TAD, strange... TAD sell his selected tubes at an higher price.

Time will talk about reliability, but at the moment they are the Winged C I'm use to and I know they will get better in few days.

Marco

Advantages: Best sounding EL34 for the money, for sure.

Disadvantages: You are going to miss them, as far as they stopped production.

Comes in 4 different types. The 04318 is perfect for Princeton, and eliminates the "bass fart" 8500 Ohm primary impedance, Princeton wants 8000. But that's no problem for the reissue anyway. Fits in slot.
Bought this earlier, probably get one more.

Very good set, lot of dynamic range. Amazing clean sound at low volume. Can sound a little bit harsh at highest gain settings.

Passt in alle möglichen Pedale mit momentären Fußschaltern, SPST. Ob das Ding den hohen Preis wert ist, lässt sich natürlich erst nach Jahren und viel Benutzung sagen, doch die Tatsache, daß Lehle die Switches in ihren eigenen Pedalen verbaut, scheint auf gute Qualität hinzudeuten.

Advantages: Sehr platzsparender Momentary Footswitch, der sich auch gut mit der Hand bedienen lässt. Die beiden intern bereits verbunden Litzen haben offene, saubere Enden, gut verlötbar.

Disadvantages: Der "Lehle" Druck auf dem Knopf... sieht billig aus, aber man kann das mit etwas Sandpapier abreiben ;) Natürlich wünscht man sich die unbedruckte Fassung, die Lehle in den eigenen Pedalen verbaut.

reliable - good sound

Advantages: warm soud

Disadvantages: none

Great tubes. I bought a matched pair and put them in my Line 6 Spider Valve. Great improvement in sound quality both in clean and drive tones.

good quality knob

Advantages: plastic quality seem better than other cheap knobs

Disadvantages: none

Great power tubes. I bought a pair to replace the Chinese ones in my Line 6 Spider Valve. Great improvement in sound.

Old school sound and really a good tube. Superb with old Princeton Reverb amp.

Advantages: Sound and manufactured quality

Disadvantages: Price?

Las compre para la etapa de potencia de un Jet City 22H que aun llevaba las chinas que venian con el ampli y la mejoria ha sido notable en todos los aspectos. Muy buenas valvulas

Good cap for replace IC caps in Fender products like : Hot Rod, Blues Jr....

Advantages: Very good quality

Disadvantages: None

A very good tube for Musicman before 1980. The sound is between EL34 and 6L6GC. The settings are identical to EL34. Also used in Brunetti MC2 to change the sound. 6CA7 is the US answer to European EL34. Its construction is very close to a 6L6GC and the sound too.Very good tube by Tesla JJ.

Advantages: Good tube and good price, the "sound" is great

Disadvantages: None

Great tubes!
Sound is clear and dynamic in my Elekit TU6800S.

This colour looks epic in natural light, magical sparkling effect, high glossy finish, highly recommended!

I use 4 my guitar

Advantages: More

Disadvantages: Less or none

Good for Marshall or Diezel type amp. Sound more cleaner than EL34.

Valvole dal rapporto qualità/prezzo ragguardevole, assenza di microfonicità, gamma medio - alta analitica e mai stancante.

Advantages: Costruzione robusta e affidabile.

Disadvantages: L'ampiezza del palco sonoro è leggermente inferiore alle Tung sol el 34B che uso sul mio Audion Stirling.

Für mich gehört sie zu den besten Röhren überhaupt.

Advantages: Schöner kräftiger weicher Bass sehr gute Höhe und ausgeprägte Mitten, dickes Glas schöne Optik.

Disadvantages: ----

Very nice switch, high quality, firm, quiet and clicky!
The best switch for me.
(On Stratocaster)

Advantages: Clicky - doesn't go easily in between stages becuase of the use of a spring (Grigsby doesn't have a spring and isn't clicky)
Thick materials - won't budge after installation
Quiet - Shaking it won't make noise (therefore doesn't affect guitar sustain)
Nice contact legs - easily solder, and stays still.

Disadvantages: Big - Bigger than standard import switches, on some guitars need isolation from the guitar cavity (because of shielding shorting with the contact legs)
Heavy - heavier than import switches
Needs a big tip - it has wider lug and fits only the bigger tips, like tele type

Das ist genau der Sound, den ich immer haben wollte. Geringes Rauschen und seidige Höhen, exakt der Sound der alten Vox Wahs.
