Key recommendations for the application receiving and amplifying radio tubesModern receiving and amplifying tubes are usually oxide cathode, consisting of a metal core (substrate) with an active coating of alkaline earth metal.Oxide cathode is the element of light, stability and durability of which determines mainly the quality of work and longevity of the lamp in operation. The best results are obtained by the lamp at rated voltage cathode heating. Exceeding the rated voltage of the cathode glow (perekal) leads to an increase in temperature of the cathode, increasing the evaporation rate of activating the cathode materials and their deposition on other electrodes. This, in turn, leads to a decrease in electron emission cathode, the anode current fall and slope characteristics of the lamp. In addition, the deposition of the activating substances on the grid and anode of lamp promotes an increase in the thermionic current from these electrodes, and also shifts the characteristics of the lamp due to changes in contact potential difference between cathode and other electrodes of the lamp. Lowering the heater voltage of the oxide cathode against the nominee (nedokal) leads to a reduction in temperature and to the predominance of the processes of decontamination cathode, over processes, activating it, which is also a rapid decrease in its electron emission.Exceeding the maximum allowable values of power dissipation in the electrodes of the lamp may cause a sharp increase in gas liberation from the electrodes and the deterioration of the oxide cathode evolved gases. Not recommended for consistent integration glow for more than two lamps (except when the lamps are designed for this), since the sequential inclusion of a group cathode lamps may be in the mode perekala, and the other - in a mode nedokala. Cathodes receiving and amplifying tubes are divided into two groups: the filamentary cathode and cathode indirectly heated.In the filamentary cathode heating current is passed directly to the metal core, which caused a layer of oxide. In an indirectly heated cathode heating the metal core of the cathode, carrying a layer of oxide is carried out using an electrically isolated from his heater. Filamentary cathode has a larger economy than the cathode indirectly heated, and less thermal inertia (heat-up time).The advantage of receiving and amplifying tubes with indirectly heated cathode is a large mechanical strength and the possibility of applying for a filament of alternating current.When operating the lamps with filamentary cathode should adhere to certain rules.1. Depending on the voltage filament lamp with a filament connecting the battery so that their voltage slightly higher than the nominal heater voltage.2. Common point sources of power grids and the anode tubes connected to the negative battery terminal filament. To adjust the heater voltage is recommended to use a rheostat, connecting it to the positive pole of battery heater.When operating the lamps with the cathode indirectly heated, should pay attention to the fact that the voltage between the cathode and the heater did not exceed allowable for this type of lamp value specified in the reference data. Exceeding this voltage can cause breakdown of insulation damage to the heater and lights. Very essential for the operation of lamps is the correct choice of resistances in the circuit of the control grid. Resistance in the circuit of the control grid should be minimal, especially for lamps with a large slope characteristics. In these lamps, with a large value of resistance in the circuit grid (1-2 MW), the appearance of small reverse current will lead to a sharp increase in anode current and hence power dissipation at the anode. In some cases, this process is growing like an avalanche, and displays lamp failure. For these reasons, the resistance in the circuit of the control grid should not exceed the values specified in the handbook for the respective types of lamps. In all cases, the use of lamps with a large slope characteristics should use the self-bias circuit supply. This scheme reduces the risk of unacceptable congestion lamps when they are changing and with fluctuations of supply voltages, provides greater stability and less dependence of the device on the individual lamps. Alarm repeater lamps are resistant to low ambient and elevated temperatures (from -60 ° C to +60 OC) and high relative air humidity (98%). Stability of the lamp at a high ambient temperature is determined by the bulb at its most heated part. Overheating of the lamp bulb causes high gas separation from the walls of the cylinder, the violation of the getter, in some cases contributes to the development process of electrolysis of glass in the lamp foot, which leads to premature lamp failure. Temperature regime of the container depends on the conditions of radiation, heat conduction, convection, determines the size and surface properties of objects that surround the lamp.Therefore, when designing the equipment is recommended:1. Avoid the use of screens in all cases where this is not due to the necessity of electrostatic shielding.2. When using screens to create facilitated conditions of heat from the cylinder tube by convection and apply screens malootrazhayuschimi surfaces (Blackened screens).3. Take into account the conditions of cooling tubes in choosing the location of items of equipment.4. Check the temperature of lamps.Maximum permissible temperature of the cylinder varies for different types of lamps. On average, for the output tubes should not exceed 150 ° C in operation.All lamps can short run in terms of vibration at frequencies from 20 to 70Hz and accelerations up to 2.5g, but if possible, should take all measures for depreciation of lamps.When using the finger and the other wedge base lamps with a rigid leads (pins), to eliminate the risk of breakage legs should observe the following conditions:1. Apply the lamp panel only factory-made.2. When installing the equipment to take measures to prevent disruption of the normal arrangement of floating contacts nests panels. It is recommended to assembling panels when inserted therein, or caliber of the old lamps.3. Insert and remove the lamp in a position perpendicular to the panel.Directions for use of subminiature lamps:1. Account of the broods being colored tags. Flexion of the findings of the glass is not allowed. Bending findings, solder them or clamping screw is allowed at least 5 mm from the crest of the legs to avoid the appearance of cracks and chips in the glass.2. Chips and small cracks in the findings that do not cause leakage within 7 - 14 days after their formation, are permissible. Sign of the lack of inflow is the presence of plaque on the dome getter container or the amount of reverse current grid within normal limits.3. To avoid bending and tension of the findings should strengthen the lamp for the cylinders with rubber grip. Allowed to mount lamps in metal springy thin wall holder, which can simultaneously serve as a capacitive screen.4. Temperature of the glass container during operation should be as low as possible. Should take steps to maximize the cooling tubes, as the increase in temperature reduces the life of lamps.Temperature measurement of cylinders shall be done using a thermocouple with a diameter less than 0.1 mm.5. In the case of lamps in the most hard mode or at a reduced atmospheric pressure, it is recommended to immerse in the coolant tubes possessing adequate dielectric properties.6. When operating at high frequency should not burn on the findings further 8-10 mm from the glass, cutting off excess ends.7. Contamination of the glass between the findings lead to a decrease in insulation resistance. Glass should be rinsed with clean water or alcohol with the help of brush.Alexander Vorobiev

kod Slobe cujes osnovni karakter a onda uzmes varijantu tog istog drivera - AlNiCoeve ti Sonido nacrt za kutiju , a od toga moze i bolje - moze da se uradi transmisijacena - po cenovniku u onoj Sonido temi - bese oko 110 par , ali mislim da je to i manje ako uzimas ditto kod njih

to drugo tesko da ces naterminisati na bilo sta :buehehe:no - ako mene pitujete - Eichman Bullit je zakon

Igor ?

ja cu da se ubijemidi kod Slobe ........

"di čeljad nisu besna , kuća nije tesna "

otvori i postuj slikeprevise je cetvrtast da ga gledas kao crystal balltrazi da li ima neki NiCd ili alkalnu kao backup

vidi sta JBL predlaze - litrazu za taj precnik

imas ti svoja polja kompetencije .......... a pored toga - svi smo kompetentni na polju slusanja muzike ( 'bes sprave i kablove)

http://www.natch.co.uk/downloads/SigJenny/SigJenny.zipimas li ili nemas JBL program ?

kutije si kupio ?a SigJenny dobijas u paketu mailom - sa JBL programomok?

gazda Niko udomio trafoe

treba ti SigJenny ili slican prog za komp koji pravi sinus signal i pokazuje frekvenciju u isto vreme - to ti je gen signalatreba tibilo kakav pojacivac treba ti multimertreba ti otpornik od 1K nekolicinu vata ( napravis ga od 10kom obicnih 10K metalfilm u paralelu)treba ti test kutijica od nesto litara - koja odgovara za taj zvucnjak (pise u programu)dakle samo pratis sta pise da radis i vidi cuda - imas parametre

da pojasnim sta sam ja mislio i napisao onomadako se ispostuju impedanse i kapacitivnosti u samom sistemu ( izlazne ulazne impedanse gain blokova ) onda kablove ne moramo koristiti da spasavamo situaciju - sto je slucaj u sistemu sastavljenim od proizvoljnih komponenata slaganih po ko zna kojim kriterijumimaonda se ulozi para/vremena u najkvalitetnije kablove koje ima smisla upotrebiti u takvom sistemunaravno da ce razliciti kablovi imati uticaja na zvuk , jer je pretpostavka da i moraju imati na visoko rezolutnom sistemu ........ ali to samo znaci da ce se cuti filterski efekat koji takvi kablovi - namerno pravljeni kao takvi za navedene svrhe flasterisanja .........ja licno preferiram sto tanje solo vodice - za IC mi je 0,1mm sasvim OK , za zvucnicki slicno tome ........neko drugi nesto drugo preferira ........

a da izmeris ?JBL SpeakerShop ima celu rutinu a ne treba ti ni mnogo znanja ni mnogo opreme

@ Steinpa nisam ti ja kriv sto kod tebe stanuju Gremlini ......

uffnista takvo ......

kuj vam djavo ?ko je uopste pominjao OB ?

ne se javljaj .....odi brljaj tamo gde si vec zabrlj'o:tongue10:

a sta fali bilo cemu sto ce manje boxy da zvuci ?

1. IRF710 , IRF720, IRF730,IRF810, IRF820,IRF8302. najmanja3. ako je napon preko te dve diode 1V3 , onda bar sledeci rang napona vise :sarcastic_hand:4. DUS - Dioda Univerzalna Silicijumska - sto ce reci 1N4148
