Re: lampe i razilke
btw ako neko zna još neko pojačalo koje može ovako da menja lampe a da ne košta dveipoiljade dolara..neka kucne
Re: lampe i razilke
Realno , svako pojačalo sa podešavanjem BIAS-a može, ...nego se postavlja tu pitanje...šta će ti to?
Ako bi da se igraš ok, međutim ,praktičnog tu nemaš ničeg osim što ćeš razlokati podnožja, pa ćeš završiti sa neispravnim lampama i ampom.
Sve se svodi na to da ćeš izmenjati i na kraju ostaviti u njemu ono što po tebi najbolje radi.

Re: lampe i razilke
Najveći problem je razmena 6V6 i 6L6. Drugi su im naponi i struje.
6V6 može u 6L6 pojačalo, obrnuto ne.
---------------
If your amp is an 6V6 SE one, don't worry, you can put 6L6 if we are talking B+, bias etc, the idle current will be lower.
But for the best load, you need to connect your 8 Ohms speaker in the 16 ohms output (6L6 in place of a 6V6)
For the best bias, you need to change the cathode resistor.
6V6 in a 6L6 amp : no.

Evo lepe analize

If you like crunchy cleans and crunchier distortion, EL34 is the way to go... the classic glassy heavier "British" sound is in these tubes. EL34s provide some of the sweetest edged tone out there, not to mention powerful crunch and glassy, shimmering cleans. Humbuckers can really round out the mids. EL-34s are also often used in consumer audio for high-end stereo amplifiers.
The modern "American" tone is 6L6-based, they are fatter and rounder-sounding and break up a bit more smoothly than EL-34s, but you don't have the crunch and tube compression of EL-34s. 6L6s have a LOT of headroom - they seem to have the most headroom of all guitar amp tubes except for KT-66s. 6L6s seem to favor tube rectifiers – tube rectifiers seem to enhance compression and give 6L6s more of a "tubey" character and feel. The 6L6 is a great tube.
6V6 tubes are for vintage American blues tones (think tweed and Deluxe Reverb.) They compress more evenly at lower relative volume than EL-34s and 6L6s. They are glassy and have a sheen to them. The highs are sparkly and cleans are very rich and deep. When pushed, they seem to have a rattle to them in certain applications – to avoid the rattle, some tubes are better than others. Many NOS 6V6s don't have the high plate voltages necessary for many guitar amp designs – that said, Leo Fender always pushed his 6V6s hard. There are plenty of current production tubes that are made for high plate voltages that work great for guitar amps. The 6V6 is an extremely musical sounding tube and has been my favorite for years.
EL-84s are for boutique-amp and vintage British tones. You get nice OD and sustain with EL-84s. The tone is round and crunchy without being harsh or trashy. The highs are very vocal and sparkly. When really pushed hard the highs are not as rattly as a 6V6 but have a characteristic "blizzard of nails" smooth rattle. Single note runs are huge. EL84s saturate earlier than EL34s or 6L6s. In general, you can get output tube distortion earlier with the same given wattage with EL84s over those tubes. The EL-84 is fastly becoming my favorite tube.
I like 6V6s and EL-84s for their musical qualities at relatively lower volume levels – the bigger bottles never did it for me. I have had problems with pedals just sitting on top of the sound with bigger bottle amps - for 6V6s and EL-84s the pedal merges into an overall more cohesive sound.
These are HUGE generalizations, and since (I admit) all of my descriptions are generalizations by nature there are exceptions.

Re: lampe i razilke
imas onog THD UniValve, ali ne znam gde moze da se nabavi. Nije nesto bilo preskupo. Mada je ono single ended class A, ne push pull...tako je malo lakse drzati bias na vrednostima od kojih nece da eksplodira ni jedna lampa koju bocnes unutra. Zaebancija je menjanje lampi jer osim bias-a treba da se vodi racuna i o izlaznoj impedansi i naponima anode. EL34 voli nizu impedansu od 6L6...iako ce raditi ok na istom trafou, nije idealno. Mozes da nabodes vrednosti napona, impedanse i bias-a sa kojima ce sve lampe raditi ok, ali ni jedna odlicno. A u kucnoj izvedbi mozes da napravis ako si dovoljno lud pojacalo sa nekoliko podnozja za izlazne lampe, par prekidaca kojima biras koja je aktivna u datom trenutku i custom trafo sa gomilom izvoda pravljenih za svaku lampu ponaosob. To bi radilo ok, ali je komplikovano i neprakticnoOverdrive wrote:btw ako neko zna još neko pojačalo koje može ovako da menja lampe a da ne košta dveipoiljade dolara..neka kucne
Bemliga, to je kao da trazis dizelasa i benzinca u istim kolima.

Re: lampe i razilke
ja ne stavljam standby na moja pojacala. Nekad jesam, ali od kad sam citao pogotovo od valve wizarda, batalio sam.

Re: lampe i razilke
Pored toga, kad me je zanimalo zašto na Classic 30 nema standby, iskopao sam ovaj artikal, vrlo lepo i naširoko objašnjeno od strane samog Hartley Peavey-ja: https://peavey.com/support/technotes/ha ... pter_6.pdf
Re: lampe i razilke
e, a ima nesto cool i u tome da se pojacalo probudi i postepeno roars into life...kao ono ta-daa
Re: lampe i razilke
TLTR. znaci da ne koristim standby?
Re: lampe i razilke
Meni ne smeta, al sam imao pridike od ljudi da mi je pivi loš lampaš jer nema to stend baj dugme za grejanje lampi. I kod ovih što ima to dugme ako se uključi power i ne sačeka nekoliko sekundi nego odmah uključi i stand by pojačalo ne proradi jer treba nekoliko sekundi da se lampe stabilizuju a i kod mene kada uključim "power" na on. Iz ovog se da zaključiti da to duplo dugme samo smeta hehe.

Svakim danom, sve vise i vise, cak i kad se trudim da to ne cinim saznajem koliko smo mi Srbi u stvari retardiran narod. Al' majke mi, nas kad nestane svetu ce biti lakse a i onoj deci koja se nece roditi ovde nego u nekoj sredjenoj zemlji na mestu ove.RadeRas wrote: al sam imao pridike od ljudi da mi je pivi loš lampaš jer nema to stend baj dugme za grejanje lampi.
