Ma ne moze germanijum da svira dobro.

samo sam tebe cekao

...forgt to show a picture of resistors....they are ceramic, noninducive and look like thiscould use other resistor witch would require smaller heatsink or none at all...or even CCS, but just....dont ask

Da nece taj orah da se ukrivi od temperature? Svidja mi se rad.

Za sad fercera, orah je suv da suvlji ne more....a ako krene..smislicemo So finaly, I managed to screw in trnsformator and all PCBs and to heatsink...sorry for picture quality

...after a lot oh hand work screwing holes,read making screw holes I realy felt like it might work after all

So the story goes on.....after a lot of temperature measurements, I decided that the most optimal solution would be a two monoblocks version. This way one side of monoblock woud be used for power resistors and other side for output transistors and power supply.Mesurments were.... power resistor cooling block was not more than 50C in room temperature during summer, and side where power transistor and supply were was even less , about 45CMesurments were taken whith unimer so might be a little higher, but even so I was happy whith heatsinks

final schm is ?

dont have it right now, I will put it as soon as I get it dont have 1t813b data either, could you post it for me, please

Veoma lep rad, svaka pohvala BataBane!Pozdrav.Borko.

Druze B, zahvaljujem

then it had to be repacked, I was lucky to find BIG pieces of Al, to cool down this heat stove

ATTACHMENT SHRINKED FROM ~500K to ~200K

ZM

then just a bit serious upgrade whit its own pover supply, so it can be taken to a beeter place for tryouts

in the begining it looked like...a junk

this was the first protoboard..whitout power transistors

After a while I finaly finished my amp...

basic caracteristics 34V supply, 2.6A bias curent...

it started like this http://www.hifi-forumi.com/forum/viewtopic.php?f=18&t=10229&hilit=sega ,but after a lot of experimentation and few changes in circuts design it looks something like this

base of the amp is Russian military Ge power transistor 1T813b, and imput transistor is AC 141K, in the midle AD 162

thiese are the glimps of my hevy metal work for now

EDIT :

SCHEMATIC INCLUDED,by bata bane request

You can sure make a field coil stronger than a neodymium, that's just a matter of the power applied. I've played around with coils as magnets previously, and sure there is a limit, but it's beyond what you'd consider reasonable from a power consumption aspect.The main benefit, would be higher flux in the voice coil gap, and a possibility to adjust that parameter. This I would expect, could turn out as a possibility to get better frequency response in the upper end. Magura

For some time I was also interested in making field coil magnet, but with voice coil patented by our countryman which made some controversies in hi-fi community, the DD voice coil

As I understand, the neodyum magnet are stronger than field coil magnet...It is a considerable job to make some thing like that...what are the adventages of such concept?regards BB

@mentoksvaka cast za entuzijazam i trud obzirom da ti je "prvi put".... da nisi spomenuo nikad ne bi rekao meti te svece pa da cujemo utiske....jos edared

Iz par privatnih poruka koje sam danas razmenio sam skapirao da je oglas malo zbunjujuć. Slike sirove kutije su tu orijentacije radi. Kutija trenutno izgleda kao na prve tri slike.Priprema za novo pojačalo je moja obaveza. Podrazumeva nov klirit u prednjoj ploči i aluminijumske ploče 10mm x 120mm x 300mm koje prelaze preko oba hladnjaka iperfektno ih termički sprezu.

ja sam zainteresovan, pile imas pp

čiča, miča, gotova priča. adapteri su kod postavljača teme pa njega davite dok se stanovita količina ne potrosi.

gujo, sta da kazem.... adapteri su superiska

ma pokupi

ah, da ...mene treba 10 komata

18 komada prvih i 5 komada drugih je izecovano.dakle?

gujo, radis na telepatiju.... juce sam iskuckao poruku, ali nisam poslao...ko da sam znaoimas moj broj...i resavamo problem na licetu mestasho bi rekli ...cekam tvoj poziv pozz

lep tekst, jedino bih dao sugestiju da se prebaci u "know how" ili "data & tips"pozdrav

ti si bata-bane počeo kviz, znači ti dolazis.biraj: vidikovac ili zemun.

druze G, ni jednog momenta nije dolazilo u pitanje moja resenost da preuzmem robu, no nisam zeleo da budem nametljiv...jel'tezemun mi vise odgovara, pa samo reci mjesto i vrjeme...a moze i nesto da se popije na neutralnom terenu ako vise odgovara u svakom slucaju za inicijativu i ekspeditivnostpozdrav bmob 064 11 57 111

ajde gujo...pa nismo deca majka mu stara, tolke eure dadosmo na sisteme pa da nam je sad mnogo za postarinu salim se, pa postekspres je resenje

gujooo ne udaraj nam ceznju, nego zbori....

o

ok. smisli količinu pa javi.

pa recimo da bih mogao da uzmem 8 komada sa tim da bih voleo da znam okvirno kolika bi bila cijena istih pre toga
