Der Austausch der Röhren in der Vorstufe kann in der Regel schnell und problemlos und ohne zusätzliche Einstellarbeiten durchgeführt werden. Bei den Röhren in der Endstufe ist dies oftmals leider nicht so einfach möglich.
Sofern der Verstärker über kein Auto-Bias (Kathoden-Bias oder ähnliches verfügt) muss nach dem Austausch der Röhren der Arbeitspunkt geprüft und möglicherweise neu eingestellt werden. Dies ist zwar kein grosser Aufwand aber nicht jeder Besitzer eines Röhrenverstärkers besitzt auch die hierfür notwendigen Messgeräte oder verfügt über das notwendige Wissen um die Einstellung selbst vor zu nehmen. Hinzu kommt, dass man unter Umständen mit Hochspannung in Berührung kommen kann und das bedeutet immer: Lebensgefahr. Daher besser den Verstärker zu einem Techniker bringen, der sich mit der Thematik auskennt ! Aber wo ist ein Techniker zu finden, der in meiner Nähe wohnt, die Arbeiten ausführen kann und normale Preise für die Einstellung verlangt ?
Alles nicht ganz einfach und vor dieser Problematik stehen viele unserer Kunden. Eine Lösung für das Problem bietet der Tube-Town Matching Service !

Rebuild of the original Tung-Sol K5881

Copy of the original type 3 Tung-Sol 6550 made in the 1960’s.  Triple getter, carbonized screen, and gold plated grid.  The current production benchmark of the classic 6550.

Large bottle type for the look and sound of 6L6 tubes used during the golden age of hi-fi in the 1940’s and early 1950’s.  Uprated to 6L6GC specs for improved performance and reliability

The Tung-Sol legacy continues with the introduction of the new 6L6GC STR. The ultimate in musical tone and smooth overdrive, the STR delivers the sound that established Tung-Sol as the benchmark of quality. Built to the same “Special Tube Request” specs of leading amplifier manufacturers of the 1960s, the 6L6GC STR is a rugged and reliable power tube for use in the most demanding guitar amplifier circuits.

The best current production 6SL7 available.  NOS performance and sound at a fraction of the price.  Sweeten up the preamp section of that Vintage Ampeg B-15.
 

Super linearity, low noise, and full performance ratings make this one of the best 6SN7 tubes ever made.  The sound signature is on par with 5692 types.  Excellent driver tube in high-end audio applications

Totally Tweed! The preferred OEM tube of ’50s-era Fender Tweed Champ and Deluxe amplifiers The Tungsol 6V6 has a geometry designed to safely handle the higher voltages used in guitar amps – plus heavier plate and grid materials. The result.. better mids and bottom while keeping the smooth top of the classic 6V6’s. The Tungsol 6V6 breaks up evenly from low E to high up the neck. Blues players will LOVE these tubes for the way they sing!

Higher impedance design with increased touch responsiveness and a unique clipping characteristic with a hint of the 6L6 sound.

In September of 1950 Tung-Sol introduced the 5881, an uprated and industrial version of the 6L6GA with a 23.5 watt plate dissipation, opening the doors to the hi-fi movement of the 1950s. This rugged tube also found a home in the '59 Fender Bassman and servo amplifiers used in B-52 bombers. In 1955 Tung-Sol raised the bar of high fidelity with the introduction of the 35 watt 6550, which could deliver 100 watts with a pair in push-pull configuration. This tube was used in the Dynaco Mark III and Sunn amplifers.

New Sensor now announces the Tung-Sol KT120, which has a plate dissipation of 60 watts, making it the most powerful tube in the 6550/KT88/KT90 family. A pair of these tubes in push-pull configuration can deliver power levels of 150 or more watts. When used at the parameters found in existing 6550/KT88/KT90 circuits, the Tung-Sol KT120 is impervious to overload, delivering peak power with extreme reliability and long tube life. However, taking advantage of the higher current handling capacity of these tubes, a very unique and super powerful and stable amp can be designed using the Tung-Sol KT-120.

The Bluesbreaker sound is back, woman tone at its finest!
