Teenage Engineering OP-1: Why won't audio come from the right channel of my OP-1?

Tue, 17 Mar 2026 18:42:12 -0700

I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!

Electronic Keyboard: Casio WK3700 DSP not working

Wed, 04 Mar 2026 00:55:41 -0700

I have an old Casio WK3700 electronic piano/keyboard.

When powered on in Grand Piano mode 000 it works fine. If I try any other mode the DSP button lights up and it emits a distorted thrumming sound and eventually powers off.

I assume the DSP circuitry is stuffed. Video

Guitar Amplifier: ¿why when I play with my amp for too long gets distorted?

Tue, 03 Mar 2026 18:45:34 -0700

basically when i played for 1 or 2 ours the red light above my FENDER HOT ROD DE VILLE 2 decreases its intensity and the sound gets an ugly distorted fuzzy sound

EDIT: i used it for about 40 minutes and it dosent turn on, not even the light :(

i checked the socket from the two big tubes and they look fine to me

i dont know maybe it's the connection that goes to the speakers? there is only one input being used, i dont know nothing about amps or circuits

Guitar: Humbucker selector switch problem

Tue, 24 Feb 2026 08:35:35 -0700

I am stumped! I just acquired a 25 year old Guild X-150D. It is great but I now have a problem. It has 2 humbuckers, 2 volume and 2 tone pots. When I select either pickup it works fine. When I select BOTH pickups (switch in centre position) only the bridge pickup plays. I have pulled out the switch, examined it and tested it with an ohmmeter. It tests fine on the meter. Both pickups connected. Any ideas?????

Behringer U-Phoria UMC204HD: I need someone to identify this circuit board component.

Thu, 08 Jan 2026 12:09:27 -0700

I'm repairing a Behringer U-Phoria UMC404HD. There was a tiny component that received both the signals of USB data(+) and data(-), before allowing both to proceed towards the XMOS chip. Please take a look at the image above to check out how the component (with arrows pointing at it) and the surrounding area looks in an undamaged UMC404HD.

There has been an attempt, by the former owner, to repair the USB connections, which left this particular component destroyed.

Could someone tell me what is this component and, if possible, the specs it might have, so I can order a suitable replacement?

I don't have much knowledge in parts names and uses, but I can do a good job, when it comes to repairing circuit boards.

Casio CTK-501: Is my Casio Keboard broken? or just the DC Power Supply?

Wed, 07 Jan 2026 18:32:02 -0700

So my Casio CT-600 Keyboard runs a DC 9V Powersupply. My friend accidentally connected it to a 220V Outlet (My keyboard needs only a 110V btw, so it has its own transformer.) After that the Keyboard didn’t work. I was planning to buy a replacement for my DC Power Supply, but before I do, I really need to know what’s broken. Can anyone please answer, I would really appriciate it. Thank you!
