ang alam ko steady na agad ang voltage out ng mga ganyan. wala ng switch on switch. ang b+ lang ang pwede ma adjust ng trimmer. iyong 12 at 5v ay steady na rin.

ano ba ang model o chassis board ang inaayos mo sis?
bumabagsak ba ang B+ ng external supply mo. pgkinakabit sa board? pg Oo.. try mo muna yang lutasin para makausad ka..
kng di nmn bumabagsak... dun ka na mag focus sa H.osc
tungkol sa osc na yan.. needed mo mgkaroon ng kick pulse sa base ng HOT para tuluyan yang gumana ang  FBT mo..

ung bang Serial version ang gnawa mo sis? normal na mahina tlga ang vcc nyan. lalabas lng yang tamang supply sa pin3 pgnag ra writer ka na sa eeprom.

pa ot: pg nagkatym ako... gawan ko ng sprint layout yang Serial version natin... para diretso na printout sa pcb..
