Nevite nekdo, jestli se da u nas koupit nekde napr. Yellow Jacket nebo GT Substitube a nac to prijde?
Nezkousel to nekdo jak to zmeni zvuk?

Re: no jo
Ja vim, ze se to da venku koupit... spis me zajimalo, jestli nekdo nezkousel, jak to zni :)
No, ja mam tech zesu vic... v posledni dobe ale hraju na samy El84, takze jsem si rikal, ze bych "updatoval" i nejakou 100W hlavu :)

Re:
Hele,to je jen redukce ze stare lampy na novou, to nejak ovlivnuje zvuk ? Jako kdyz si odmyslim tu zamenu lamp je v tom jeste nejaka finta ?

Re: Carlo, tandel
Finta je v nahrazeni napriklad nepeknetvrdejch 6L6tek crazysexycool a stavnatejma El84kama a jeste k tomu v class A.

Re: batty, @ll
Presne jak pise batty, tak jako hraje jinak EL34 ve srovnani s 6L6 treba, tak jeste daleko vetsi rozdil je v pentodach a triodach. Navic A trida je uplne o necem jinym nez AB...

Re:
Cilem, ale bylo hlavne snizeni vykonu. Slysel jsem, ze jde u zasilovacu s vice pary lamp(4) kombinovat yelowjacket s puvodnimi lampami. Treba 2xEl34 + 2x El84

Re:
Vcera jsem se na to ptal telefonicky jednoho technika a rekl mi, ye to jsou hlavne substitute pro stare lampy treba 6V6 na EL84 nebo podobne Dost pochyboval ze rovnou vymeni nekdo za 6L6 treba tu EL84, ledaze by to pry byl nejak slabcak s 6L6 ve 20W, tam by ty EL84 mohly prezit. Jako trema Mesa fftyfifty ma pry na lampach 480V a to ta L84 prezije tak na 10 minut. Nebo jestli v tech Yeloww nejsou navic nejake soucastky...

Neumis cist chlape?
"Yellow Jackets® Converters are a type of specialized adapters which permit the use of EL84/6BQ5 power tubes in place of 6V6, 6L6, EL34, and 7591 types."
"They give you simple Class-A operation from any amp.Yellow Jacket® Converters not only rearrange the pin locations of the tubes, but also provide the necessary current limiting on the screens and cathode as well as blocking the amplifier's grid bias voltage, while configuring the EL84 in a Class-A, Self-adjusiting cathode-bias circuit. In other words, there are no adjustments to make and no modifications necesary, you simply plug the Yellow Jackets® into the amp's output tube sockets, (in cathode-bias amplifiers) screw the ground wires under one of the output tube socket mounting screws, plug the provided EL84's into the Yellow Jackets®, turn on the amp and play."
"Will they hurt my amp?
No! Yellow Jacket® converters are safe for all amplifiers and transformers. As all Yellow Jacket® Converters internally limit voltage and current they put no extra strain on amplifiers' power and output transformers or internal components. Using the Yellow Jackets® in higher powered amplifiers actually reduces the strain on the transformers and internal components because it reduces the overall wattage of the system. Furthermore, the heater (or filament) current of the EL84 is lower than that of the 6L6, EL34 or 7591, so the Yellow Jacket® will reduce the strain on the filament windings of the power transformer as well."

Obdobnou vec vyrabi Groove tubes. Tady je test YJ vs. substitube, ale jeho objektivitu bych bral s rezervou http://www.groovetubes.com/assets/1778_GT928-PR_vs_THDYJSD_Test.pdf
