VINTAGE

[jagnje]

sem potegnil ven kabl od računalnika, tako da je feršt stal sam, ter nepovezan in je šum enak.

Vzemi eno navadno žico in en konec žice nekako pritrdi na ozemljitev od zidne vtičnice. Z drugim koncem se dotakni zunanje žice na činču, ki je na enem od vhodov v ojačevalec, ali pa ga priklopi na ozemljitev od gramofona, če imaš phono opcijo. Nato poslušaj, če bo razlika.

Upam, da veš kje je ozemljitev v zidni vtičnici. Če ne veš, NE POIZKUŠAJ POPOLNOMA NIČ, da te ne strese.

Praksa kaže, da odstrani vse ozemljitve, to je vedno vir težav in masnih zank. Če govoriš o šumu, ga ni moč izločiti, če govoriš o brumu, je masa vedno in vedno odveč..

če vzrok ni v računalniku je najverjetneje kak suh kondenzator,sploh napajalni...zato jaz vsako starino razstavim in vse kar je kritičnega in podvrženega staranju zamenjam.....ponavadi je tudi to nekajkrat dražje kot aparatura sama, zato vsakemu govorim naj ne kupuje stare krame zato da bi prišparal ker definitivno ne bo, ampak le če ima do tega kak resen odnos in je v vrnitev v najboljše možno stanje pripravljen investirati

Imam jaz podoben problem, če ojačevalec (prav tako vintage) priklopim na en računalnik se sliši tihi brum. Tega bruma ni pri gramofonu ne CDplayerju, kasetarju...najprej sem pomislil, da kaj s kablom ni vredu ampak, ko sem probal priklopit še drugi računalnik na isti kabel tega bruma ni bilo.

bom poskusil z ozemljitvijo, ampak je res bolj šum kot brum...verjetno bi blo res treba malo kondenzatorje osvežit.
Brez skrbi, to staro kramo kupujem zavestno, preprosto ker deluje...kakšen servis na desetletje in šiba dalje, medtem ko zamenjaš par novih plastik fantastik zadev.
Imam kitarski ojačevalec, ki je tudi cca. 30 let star star. Zamnjam lampe enkrat letno, dam tistih 100€ in to je to. Glede na to da ima kakih 30 špilov na leto, se ga preklada po kombiju, se ga tera na polno je to res minimalni strošek
Se bliža kmalu tudi servis kitarskega feršta, pa bom lepo oba nesu tja.

Ali mogoče ve kdo kaj več o seriji zvočnikov AR 58S.

Janez tule je nekaj tehničnih podatkov...




Tole sem pa našel na enem od forumov:
The first generation of the AR-58, circa 1981, was a legitimate, quality AR speaker in the time-honored tradition of the company. It used essentially the same drivers as the floorstanding AR-91: the same 12" woofer, a 1 1/2" dome midrange, and a 3/4" dome tweeter. The dome midrange was the AR-9/90/91 generation driver, not the 3a/11/10pi unit.

The speaker was housed in a genuine walnut veneer enclosure, and was of "large bookshelf" dimensions. Quite a good product, but very short-lived in its original guise.

Shortly after its introduction, the speaker morphed into the AR-58B. The high-quality, wide-dispersion (but very expensive) dome midrange was unceremoniously discarded in favor of a 4" cone midrange driver, marking the first time ever an AR 12" 3-way speaker did not use the company’s best drivers for the mids and highs. The 3-3a-LST-11-10pi-91-58 winning streak of superb 12" 3-ways with dome drivers had been broken, as AR began to cave in to the competitive pressures of its rapidly disappearing market share and vanishing profits by cheapening its product line. It was also during this time period that AR stopped making its drivers in Canton MA, and instead, farmed out driver production to Foster/Tonegen of Japan. Tonegen was one of the world’s biggest, most capable OEM driver manufacturers, but nonetheless, it was the end of an era when AR stopped making their own.

(AR did introduce one additional 12" 3-way domed driver bookshelf speaker a few years later, the AR-78LS, which utilized the "dual dome" mid/tweeter arrangement of the 9LS and 98LS. The 78LS was reviewed in High Fidelity magazine in the April 1984 issue. It fared pretty well in the review, with comments like, "The resulting balance strikes us as very natural…AR has taken a classic configuration, retained all that was best…and made it radically better." Still, the 78 didn’t exactly have a 3a-like impact on the industry.)

The 58B was a very large bookshelf or small floorstander, with vertically-oriented styling, standing 26 3/4" tall. Its crossover frequencies were 600Hz and 4500Hz. It was introduced in 1983.

The 58BX followed in 1985. It was essentially identical to the 58B, but was a little taller at 30 1/2" (strictly a floorstanding model). The crossover remained the same at 600 and 4500Hz.

Next came the 58BXi. Again, it was a floorstanding 12-inch 3-way with a 4" cone midrange and crossovers of 800Hz and 5200Hz. The increase in midrange crossover frequency from the first to last generation of the 58 was a probable indication that AR was cheapening their crossovers by using smaller, less expensive woofer chokes, and paying less attention to their original company principles of wide dispersion and uniform energy response. If anything, it’s very likely that a good 4" cone driver would have a significantly lower resonance than a 1 1/2" dome, which would mean that AR could have crossed the 4" driver over even LOWER than the dome midrange if ultimate performance was really their goal. But it wasn’t.

Corporate survival was their goal.

The 58B-BX-BXi were respectable sounding speakers, but they were a far cry from the industry standard-bearers that preceded them.

Ker to naj bi bili bookshelf zvočniki pa me zdaj zanima glede njihove postavitve.Občutek imam da ob steni igrajo bolje pri prebiranju foruma pa pravite da zvočniki naj ne bi bili ob steni.Sedaj jih imam na tleh ali bi jih bilo smiselno postaviti na stojala.Se opravičujem ampak sem bolj laik v teh stvareh tako da je vsak nasvet dobrodošel.

[NCC2000]

Ti jih kar pusti tako, kot ti najbolj igrajo. Le višino ušes (glede na namestitev slušalca) bi bilo za poravnat z visokotonci (ali obratno..).
