  1. Nope. you dont have my username. im building it for a guy called Filip in Malmö. I measured straight from the power supply. i found another one that was 500mA and it didnt seem to get as warm as before. i have a low power lcd. i think its allright. thanks for all your feedback! i have enjoyed building this kit very much! and i have learned alot but it was never to hard! great kit!
  2. Allright. checked my power supply. its 1,5A. ill see if i can find another one. it outputs 12.26 volts. its one of those that you can adjust the voltage. will it help if i set it to 9v? does the synth need 12v if i use 6582a? the pcb gets really hot say 5cm around the heatsink area. btw, it sounds really really good! better than i had imagined!
  3. problem solved. i realized it needed a stereo-cable. but seriously, should it be that hot? the pcb is almost to hot to touch down under.
  4. Just finished building my sammich and it seams to work fine. But when i use polyphonic sounds one of the sids dosnt want to make any sound. =( did i miss something? do i have to assign the voices somehow? i tried switching place of the sids but its still the the right one that isnt sounding so i assume they are not dead. (6582a) also, the heatsink is very very hot. any thoughts?
  5. allright! thank you! im checking with another multimeter now and it shows 9.15 k both ways. i dont have any ic:s installed. i guess it could be the caps loading up. the electrolytes are all the right way. well. thanks for your help! now i can get back to building! peace!
  6. Hijacking thread: Iv just about assembled my base pcb and decided to make the 5v - gnd test. and it reads about 5k if i put the multimeter one way and about 10k if i put i the other. is this normal? iv double and tripple checked my solderings and i cant find any bad ones. i havnt soldered the voltage regulators yet. if i put it at 9v - gnd, there is no leakage. thanks
