27.05.2010: 19-zoll stammtisch #26

pizza?

flyer 19-zoll stammtisch #25: transistor says "pizza"?

batch codes can be funny too - C945 manufacturors seem to like PIZZA… are there other culinary semiconductors? TL072 CURRY? or BC547 WIENER?

raumagent alpha live demo 2010

snippets from studio jams while working on tracks for a brand new liveset:

TR-909 PSU fix

TR-909 - the holy grail of bumm bumm
why would someone drop a 909 to the floor while it´s running?
i got no idea either, but recently it happened to a friend. his TR threw a few sparks before the main fuse of his studio blew and gone was the bumm-bumm :(

not to rain on roland´s designing skills (and given the fact usually you don´t throw a 909 on the floor) but the position of the original PSU board is somehow dangerous for flying 909s; since the AC solder pads directly face the bottom plate any impact in that area possibly short-circuits the main AC power. you better put some cardboard or isolating rubber between the PSU board and the bottom plate - well, it´s best not to throw 909s on the floor too ;)

unfortunatelly in our case the the shorted AC line was led to the voiceboard PCB through the metal battery compartment, blasting a few semiconductors and GND traces there. see the picture for details (note the PSU has been exchanged on the image already):

fried 909 - spark impacts on the bottom plate, smoked battery comparment and blown traces

certainly the main transformer was blown after this accident. as the 909 had to be returned into its productivity environment asap (sic!) there was no time to organize a suitable transformer so i had to exchange the PSU completely…
