Hi all
Got a non working Beomaster 8000, recapped 5 V regulator and Powersupply board but still not working.
Display comes with random numbers, Keyboard is not responsive because only "PHASE 1 " is comming sometimes and with wrong frequency, btw. 2 Mhz crystals are new, 2MHz is present, railvoltages are present and clean, caps are new.
Reset circurit and voltage for LED / PHASE is adjusted to service manual values.
After swapping the Controller IC's from my working BM 8000 the amp was working, figured out that the Master IC is dead.
First time a dead CPU, very rare but.....
So my question is if there is someone who has a working IC3 type 8340238 or a spare uPC board in stock for sale with a reasonable price.
Please PM me with price incl. shipping to Germany.
Thank you very much for digging in the dungeon
Kind regards
Christian
Seems that the controllers are really rare...
Seems that these controllers are very rare and hard to get
