project B500 with sanken
this 2 day i finish build my project B500 with sanken with test for 1 day without protect and successfull . i use wood box for this project. but maybe i will check for any error again. i use suplly 15A 45VAC with 8x 10.000uF for this project. and my problem with zobel its fix now (yes, error happen because some oscilation with my amplifier). very confuse but not hard to finish this. thanks mr. mile. thanks Apex Audio for great HI-FI Amplifier.

An externally hosted image should be here but it was not working when we last tested it.
B600
Is this picture of your B600, any comment about B600, is it work?

yes it's true B600, I already fix. The PA is functioning properly, but a lot of components that I replace the transistor BC can not be used when using the PA transistor BC the negative rail will not work, continue to flow on out sp. after, transistors BC, I replace the use of type, 2N5401 & 5551 PA can work, there is another component, I, replace pada.resistor 3k3, I, replace the 680 and 560R resistors, I, replace. 150R and VR, I, ganti.1k. Nothing is left to the transistor MPSA42 & 92, I, using 2N5401 and 5551. sorry, english, my, not good. only, that's all I did on the B600
nice job sir..
how about sound,dc offset, and evrything all. What deference with b500.?For his comment maybe most people confuse like me too, what his mean , this for simple word.
He replace all pair of BC transistor with 2N and all pair MPSA with 2N too. He change some bias adjust with 680 - 150 - VR 1k.
Just for clarify, this tr its same to 92, but different pin out, BC560,550 (CBE). MPSA42,92 (EBC)
2N5401,5551 (EBC).
Please check again, i think this schematic is right and fix please check ur layout again
.
its your b500 tef ? Right? I not see any isolator between tr and headsink, be carefull sir.
regard.
ok,. I understand what u mean sir, but my question. Why u not use bc ? I think it same tr, but different pin out, maybe u put wrong direction for this tr.
But its ok sir, can u share for all diyer, all about b600 ? Are u like b500 or b600?
DC servo is still there, sorry if iam wrong. Input balance and with inverting. More bass response.
