bata bane Napisano Septembar 11, 2009 Share #1 Napisano Septembar 11, 2009 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 ZM Link to comment Podeli na ovim sajtovima More sharing options...

bata bane Napisano Septembar 11, 2009 Autor Share #4 Napisano Septembar 11, 2009 then just a bit serious upgrade whit its own pover supply, so it can be taken to a beeter place for tryouts Link to comment Podeli na ovim sajtovima More sharing options...
bata bane Napisano Septembar 11, 2009 Autor Share #5 Napisano Septembar 11, 2009 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 Link to comment Podeli na ovim sajtovima More sharing options...

bata bane Napisano Septembar 11, 2009 Autor Share #9 Napisano Septembar 11, 2009 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 Link to comment Podeli na ovim sajtovima More sharing options...

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 Link to comment Podeli na ovim sajtovima More sharing options...

bata bane Napisano Septembar 11, 2009 Autor Share #14 Napisano Septembar 11, 2009 ...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 Link to comment Podeli na ovim sajtovima More sharing options...

bata bane Napisano Septembar 11, 2009 Autor Share #16 Napisano Septembar 11, 2009 ...at this time I still didnt know what would be a final solution for conecting the heatsinks together, for some time was also thinking about conecting these four like Pass did with his heatsink cubes... :clapping:but because of probable back problems I decidet to go with monoblocs afterall :dubbio:it is good that heatsinks could stand by themself without support and that gave me a good picture how would it look like...

bata bane Napisano Septembar 12, 2009 Autor Share #18 Napisano Septembar 12, 2009 Omađijao si JAMO-e kad si im turio Ge....pa kazem ti ja, germanijum ima dusu... ...a sad kad krenu da me pljuju -----finaly I decided to use Al...all parts are 5mm thick, and hand machined...heard Leonardo was wery busy and I was in frenzy and needed it fast. gentleman from MOC-Masinski Obrazovni Centar was wery happy to do that for me....so when you look at it you can see it is not done whith CNC but I am ok whith it, it is just fine left piece goes down, midle one goes on the top, an the right one goes on the back of heatsinks Link to comment Podeli na ovim sajtovima More sharing options...
bata bane Napisano Septembar 12, 2009 Autor Share #19 Napisano Septembar 12, 2009 so again screving holes...the next picture is assosiated with pain, blood and tears... the mathematics goes like this... every heatsink has 12 holes, 4 of them have 48, every hole have to be done with 3 step tool so it about 144...and evry tool bit during driling should be cleaned 2-3 thimes before goes all the way down the hole....so I will remember number 432...
