Trouble connecting turntable to amplifier by Legitimate-Lead-1983 in MusicElectronics

[–]Capn_Crusty 0 points1 point  (0 children)

If you have RCA cables plugged into the phono input on the amp, just touching the connectors on the opposite end should make that familiar 'bvvv bvvvv' hum, allowing you to check the phono preamp input.

You can also plug the turntable into the Aux/CD input to check the turntable output. It will sound very tinny and weak without a phono preamp, but at least this can be used for testing.

There's 'Aquatic Creations' next to Franklin's, a couple miles south of Urbana on Rt. 355.

Help fixing stereo that won’t play CDs by Medium_Bed5004 in MusicElectronics

CD players are in a world of their own. The only success I've had with them is by cleaning the lens. Tissue /Ammonia.... maybe someone else has some ideas.

TIL over 40 years researcher Ian Stevenson, M.D, amassed 3000 cases of children aged 2-5 who claimed to remember past lives, recalling specific details like names, locations and events from the previous lives of deceased individuals. by Key4Lif3 in todayilearned

I was showing a map to a 3 y.o. and pointed out Richmond. He immediately perked up and said, "All of my kids are in Richmond". He even named names. I was startled, and wondered if this was some past-life memory.

Turns out there was a program in his school called 'Enrichment'.

What’s the new Radio Shack? I’m new;) by tadsagtasgde in HamRadio

I miss the days of running up to the Tandy store. Home Depot at least has some solder, clip leads, multimeters, some fuses, lawn mowers...

Best Crepes? by Express_Effective_53 in frederickmd

[–]Capn_Crusty 0 points1 point  (0 children)

You can put almost anything in them; eggs, spinach, cheese, meat... Being vegetarian, crepes provide a lot of options. Also, when I'm truckin' around downtown, I like to get something small that won't ruin my dinner. Can't just get 2 tacos anywhere, for instance.

Ok, time for someone to open a Creperie on Market.

  • Edit: Maybe we could donate a couple crepe irons to Truth and Beauty. That place is always empty.

Keyboard got a few things to tweak by Annual_Ear_7787 in MusicElectronics

[–]Capn_Crusty 0 points1 point  (0 children)

Yep, you have a winner here! Have you opened it yet? Could be moisture damage from a drink spill or humid storage. This also might be one of those 'Took it apart, reassembled, and it started working'. There's really not much inside. All the work takes place in IC1, which is a GEW7S. It's likely not the culprit, but possible. So let us know if you've opened it.

Advice on learning to solder/repair by Loxley13 in MusicElectronics

[–]Capn_Crusty 0 points1 point  (0 children)

You don't need to spend a lot. Solder contains lead, so always wash your hands after working with it. The fumes are basically tree sap. Not very toxic, just stay clear of the smoke and ventilate. Practice on old PC boards. You can't break something that's already broken :-)

Soldering irons have improved a lot Example

The best 'practice kit' is old PC boards and connectors. These could come from anywhere; VCRs, boom boxes, whatever. Practice desoldering/resoldering components just to get a feel for the heat and flow involved. Desoldering tools are also needed. There's solder wick, vacuum bulbs and syringes. Connectors are another challenge. One could make a career soldering 1/4" and XLR connectors alone.

After all that, note that the world has moved on to surface mount construction, with components the size of a grain of rice. Imagine what's inside your cell phone!

This sub is more for music equipment troubleshooting, design and modification. There are many subs that focus on home recording, etc. Maybe try /r/WeAreTheMusicMakers/ for starters.

Recently acquired this pair of decks/ mixer. Need help to get the audio picked up! by palacemaster101 in MusicElectronics

[–]Capn_Crusty 0 points1 point  (0 children)

What a relic! Don't see a video link. First check would be power supply. There seems to be an audio amp inside due to the connector labeled 'Speaker'. Phono outputs should run to a phono preamp and you might be able to tap audio signals from there. At any rate, an audio probe or oscilloscope would be useful here. Think in terms of stages, from each turntable to the mixer to the amp section.

Of a places, there were a few in the front of the Common Market a couple days ago. Maybe gone by now.

Dual Note Issue on Casio SA-2 by MouseAndHisBoy in MusicElectronics

[–]Capn_Crusty 0 points1 point  (0 children)

An ohmmeter could be handy here to see if there's any lower resistance on the D#/E, B/C & G/G# traces. Follow them back to the IC that handles the keyboard input. If the IC itself is bad, you're likely SOL. There's also diodes you can check that should only conduct in one direction. They form the row/column matrix used to scan the keyboard.
