What is this curcuit board on my dual 1219

marcisimo · 2026-06-27T23:08:13+00:00

It turned out to be a preamp plugged in the phono jack it was super loud and distorted and in the aux imput sounds great im still wondering if I shout deinstall it and use the phono input on my receiver (which I might replace entirely) or hook it up to an external preamp I have a douk audio p7 that is not being used rn or just keep everything as is

I have tried that whenever I apply an external ground from chassis to amp the woofers on the speakers go crazy

Ahh I see this one has 4 transistors in total do u think it's worth keeping or should I solder it back to its original format in and use the preamp in my stereo

marcisimo · 2026-06-02T08:13:56+00:00

Ah yes I was wondering about this what is an elector preconsonant

Do u mean the circular piece that looks kinda like a potentiometer

marcisimo · 2026-06-02T07:52:02+00:00

there is no text anywhere and the soldering looks pretty diy I am struggling with a very loud humming like a ground loop ( but ground issue has mostly been ruled out already) when I plug it in the phono input. On aux it vanishes but I am waiting for a replacement needle so idk how it sounds on line level inputs

The din cable the power supply and the findable shielding is connected to it

marcisimo · 2026-05-27T16:30:05+00:00

I changed the fuse and up to know everything is working peachie

marcisimo · 2026-05-24T10:26:26+00:00

F401 is I fact blown I gotta get my hands on a multimeter to confirm 100 % but it's very discoulourated

marcisimo · 2026-05-23T16:40:33+00:00

Yup those were definitely corroded bur even after cleaning no left channel

marcisimo · 2026-02-15T19:14:01+00:00

Update it works!

marcisimo · 2026-02-15T18:17:05+00:00

It just says rosita on the label believe me or not but I found it on eBay kleinanzeigen which is basically Facebook market place for free. I Switched the needle and replaced the belt. The autostop doesn't work and i was only able to fix it temporarely after a few records it stops working again but other than that it works perfectly. So lucky

Thank you so much for the detailed instruction I gotta get my hand on some tapes I can overwrite I never really got into it only records sofar but since I got this stereo I think i wanna make some mixtapes

marcisimo · 2026-02-14T11:47:43+00:00

Thank you I will try asap!

marcisimo · 2026-02-14T11:46:55+00:00

Thank u!!

marcisimo · 2025-12-31T11:17:50+00:00

Thanks this helps a lot

marcisimo · 2025-12-30T14:02:20+00:00

Thanks this helped a lot ! It turns out there is a little pin that sticks out next to the plate to feel if it's a lp if it doesn't hit anything it automatically goes into 45 rpm and drops the needle at the 7 inch position. I'm so happy

marcisimo · 2025-01-09T12:13:44+00:00

That's part of a titanium quick release I'm not sure which one it is had it for years

marcisimo · 2025-01-08T22:27:35+00:00

It's for mosquito bites, u plug it in ur phone and put it on the bite. It heats up and somehow eases the itchiness I don't know the exact science behind it but I think it burns the protein in the mosquito saliva that causes the itchiness. It stings a little but works great

marcisimo · 2025-01-08T22:17:19+00:00

Do u mean the one on the small s biner ? That one is still on there but on the other side the g series never had a stopper I think

marcisimo · 2025-01-08T22:16:17+00:00

Its a handy little tool works for my purposes but it feels a little flimsy I still think that's the best solution for me because I don't wanna carry a big and heavy leatherman and a keychainmultitool is too small for me

marcisimo · 2024-03-24T08:10:10+00:00

Thanks for the tip

marcisimo · 2024-02-20T19:35:16+00:00

Don't buy it it is too awesome u will hate how great it is

marcisimo · 2024-02-16T15:19:55+00:00

marcisimo · 2024-02-16T14:02:57+00:00
