silver = black > wood for hifi

>>61823211
it looks nice but is that hifi?

I have a UMC204HD and SC-88 as part of my audio workstation setup, and my apartment is so small it's also my stereo (thanks mpd).

>>61823853/
Provided the sound quality was good, why wouldn't it be?

I have more stuff in mothballs or on the work bench.

Can you guys help me?, I want to setup a 2.1 system for my bedroom tv but the waifu don't want a receiver as it's too big, i'm thinking on buying the smsl q5 but i'm open to suggestions

DIY 2.1 TPA3116 (2x50w+1x100w) + ~250w 24v PSU
Mount it in a box that can be attached to the VESA mounts on the back of your TV (unless TV is already wall mounted then get creative an hide it somewhere else)

>>61824260
define "higher end". I have a modern sony "boombox" with a 10" woofer (and supports their hi-res audio crap) but I still don't see how those things would be high end at all.

If you get one of those master/slave 'smart' powerboards, you could even have it switch on automagically when you turn the tv on.

>>61822762
Yes.

Nice, but not high end stuff. Most of it I got for nothing or next to it and refurbed them.

How do you refurb stuff?

Any chance I could get some help figuring out what's wrong with my JVC AX-44 stereo? :x

I have a DVMM, but I don't currently own a soldering iron (might buy one, though, if the diag and fix is easy enough)

>>61825059
Not sure how to define it without you listening to some, but an all-in-one system isn't by definition more inferior to a stereo amplifier and speakers, since that equipment could be garbage and people wouldn't have a problem referring to that as hifi simply based on visuals.

If interested though,

>>61825715
If you don't even know how to use a soldering iron, you're hopeless. Bring it to a repair shop.

>>61822762
I bought a rare *tape* (singular) a few months ago for $80. Still looking for a nice chrome capable dolby deck to listen to it on. Only have walkmans atm. Tape prices are going up.

Is this the audiofool thread?

What's Hi-Fi? 100dB S/N Ratio? If that's the case, it only came out after CDs. Your retro receiver looks Real Cool, but everything before CD was referenced to the Best Quality available at the time: FM. And that's 50dB S/N. Sorry Boss - it looks Cool, but a Jawbone Jambox will sound better. Just wait till you find out about Hi-Def Audio!

>>61825715
It's pretty straight forward stuff. Most of them just needed a good cleaning inside and out, deoxing the controls, tightening up connections and fasteners, replacing a few burned out bulbs, and measuring and adjusting DC bias. If any special components (I/C's or unique output transistors) are shot, then it's generally not worth restoring.
So far, the only one that needed new caps was the Hitachi at the bottom.

>>61826402
Good, then this still counts >>61824260

>>61825715
What seems to be the trouble with it?

>>61826402
I'd wager a TPA3116 with a linear PSU instead of switchmode would whoop most any of the amps posted here and probably cost less than $100 all said and done.
Pair it with an XMOS dac and you've 32bit/384khz audio at >104db snr from usb/spdif to speakers for under $200.

Not to mention that older amps use shitloads of power idle - A bridged TPA3116 (for ~150w @4ohm mono) uses less than 1watt with no input and in a subwoofer usage case will use less than 10watts to fill a house...

Yes, I love me some TPA3116s, they're my new favourite chip after TK2050+STA508/510.

>>61827068
Is this just a board you make an amp with or something? Can you buy amps with it already installed?

>>61827107
It's a chip - but yes you can buy lots of diy amp boards off ebay/aliexpress, some better some worse.
You can also buy full made amps, in cases ready to go, they quite often go linear rather than switchmode (for the uninitiated, if you see a big-ass coil next to the power input - that's part of linear psu, it's uses a transformer coil to drop voltage and a rectifier to go from ac-dc)
'crappy' (poorly made) switchmodes combined with poorer designed amp boards can add switiching noise to the output (since a switchmode PSU works by switching a diode on and off at many hundred/thousands of Hz to make a new voltage on the other side, whether it be AC or DC)

Aliexpress is great for finding cheap quality amps and cloned amps (lots of headphone amps have been cloned with cheap but equal quality reproductions without the markup)

What? Do you even understand anything about how amplifiers and such are tested? Either you're talking out of your ass, or I need some clarification. I think that it's the first one.

>>61827189
The thing about aliexpress is that the quality is pretty hit or miss. A lot of the cheaper amps either lie or use deceiving numbers simply because they know that no one is going to check or care if it is cheap enough.

Is a DAT walkman hifi

>>61825849
I know how to use a soldering iron. Not that I'm particularly experienced with one, but I know how to use one.

>>61826460
I have a feeling it might be a bad mosfet? But, I don't know how to go about diagnosing this stuff, so I can't really say. Visually, all the internals appear to be fine. Fuse is good, no popped caps, no burned components, no obviously broken or damaged traces/wire/etc. But I'll pull it out and take a pic in a little while. Maybe you'll see something I missed.

>>61826500
It powers on, but no longer outputs audio. It's been a few months since I last played with it, so I don't remember whether or not it even displays input on the amplitude/input meter.

The best guess I have is that I was woken up one night by a loud bang - even my dogs, which happened to be in my room, seemed confused. I thought something had fallen, but didn't find anything. Over the following few days, there was a faint smell of burnt plastic/electronics. But I couldn't find the source

>>61828827
>no tape

dam

>>61829015
I'd passed out with the stereo on, so yeh. Figured that was the source of the noise and smell. But again, the smell was pretty faint.

>>61827068
also wew, i knew that had to be some downside to using this old stereo system. It certainly gets toasty even when left idling for a few hours.

Okay. Just plugged it back in and powered it on. Faint plastic smell is definitely back. Seems to be towards the front of the unit. That standing brown heatsink is hot as fuck, if that indicates anything. Not sure if that's the source of the smell.

And then front and back just for reference.

So, I plugged my phone in via the CD/aux connectors, and the unit doesn't seem to recognize any input. iirc, it doesn't matter if it's from the CD/Aux, the phonograph, the tape, nor the AM/FM tuner.

Doesn't appear to recognize any inputs. Faint smell of burning electronics. Not entirely sure which component it's from.

>>61824260
>but aren't the higher end ones actually really good
No, because they are mostly made with thin-walled plastic cases that vibrates on higher volumes and distorts the sound.
There are monitors with plastic cases, but they are really thick-walled, i.e. you can build good speakers with plastic cases, but at this point of material costs you might as well use wood products.
