maple "mavica" syrup [6502] @mavica_again@computerfairi.es

looks like the transistor it was tapping into might be dead and the bodge was there to keep power going through the board? it's a BC337, i don't have any equivalents.. i found some BC548s in my parts box but they're rated for lower current than the 337

so now i need to figure out why that bodge wire is there and how to fix the original issue without introducing hum

so i think i found the issue.. there's a bodge wire i thought could be factory but on second inspection isn't, it's bypassing output of the bridge rectifier into the emitter of a transistor, i'm not sure why, but once i removed it the hum was gone... along with the FM circuitry

this boombox is such a cute little unit without the speakers

i guess today is a spend the day in the workshop day

there's no visible damage anywhere, no leaky or blown caps, no broken traces or cold solder joints. does anyone have any experience with audio amps of this vintage to give me a hand on where to start troubleshooting the hum? 2/2

i have an 80s Toshiba Bombeat SX-28 boombox, it uses a TDA1515BQ amp. there's a rather annoying hum on the left channel but not on the right one, and it doesn't seem to change at all in volume with the volume knob or disappear if i mute the left channel with the balance knob 1/2

i wish i could have friends like everybody else

one more!! if we can get 7 more unfollows i can be back below 800 by the end of the night !!!

bye 1 follower who couldn't stand the past couple of tweets

i forgot i can't say anything about how bad i'm feeling on twitter without people liking that i'm feeling bad

do you enjoy my misery? is it likable? marketable?

why are you favouriting that lmao

honestly it's my fault for thinking that anyone would talk to me

"oh a notification! someone is finally talking to me!"

"we've received your 5 reports over the past hour"

"ah."

does anyone have a discord server i can join
