    To DAC or not to DAC...that is the question.

    I have a modest set-up..Sony PS-LX310 TT (from the 80’s not the current Bluetooth model of the same name) a Sony DVP-S7700 cd/dvd player and a JVC RX-717V receiver. Will I see a significant jump in audio quality if I use a $100 DAC (such as a schiit mod 3) for my turntable or CD player instead...

    JVC A-GX3 Volume spikes sometimes

    Hey guys, I've got a question about my vintage JVC A-GX3 stereo amplifier. I bought it about 2 years ago and it was supposed to be refurbished and cleaned. This wasn't the case since the right channel has a tendency to suddenly become much louder. I've cleaned the sliding potmeters for volume...

    What do you know about this peculiar 1970 JVC quad receiver?

    I'm smitten, staring into the big green eyes of this JVC 4MM 4600. It's kind of delightful to me. Jeepers creepers. I can't decide: Is it ugly? Is it gorgeous? Both? JVC is one of those brands I know very little about -- although I had one of those slate-colored JVC double cassette decks in the...

    Bass and HF drivers for JVC Zero 5 speakers

    I have a pair of these which are missing their original bass and HF drivers. Just wondered if anybody on AK had ever successfully fitted replacement units and, if so, what?

    JVC full-range speakers, anyone have experience with them?

    Hello, let me start off by saying that I'm sorry if this is the wrong sub-forum to post this question. I've been in the market for a pair of tiny speakers for my desktop PC, and I've heard nice things about, believe it or not, the 3" full-range speakers that shipped with JVC micro-systems of...

    Has anyone here ever ordered replacement circuitry/parts from Union Electronic Distributors?

    I have a JVC QL-A220 turntable from the early 80's, my first "real" turntable. The auto return function doesn't seem to be working, and I narrowed it down to a missing engagement lever in the turntable's inner workings. However, I couldn't find the missing lever anywhere inside of the turntable...

    Looking for opinions - Sound of the 70s vs Look of the 80s?

    Just looking for some opinions. I am currently running a Sherwood S-7910 that sounds beautifully warm through a pair of Polk Monitor 5jrs in my small home office. It's a great receiver, does everything I need it to, and looks great even with one bulb in need of replacement. My dilemma? No...

    JVC DVD Cinema System TH-R3 wont registre Optical Cable

    I've recently bought a Chromecast: Audio to connect my JVC so I could play music with the use of Spotify or other digital music applications. I then discovered that connecting it to the JVC was not possible with the cables shipped with it, so I decided to buy a 3.5mm.minijack-optical converter...

    JVC L-A55 tonearm resistance issue

    I've got a JVC L-A55 table in the shop right now, and this thing has me stumped. When I first began messing with this table there was so much resistance in the first quarter of the tonearm's arc, that it wouldn't move at all under normal operation. I've re-lubed the auto return mechanism...

    Diode Identification for JVC JA-S55

    Hello All. I need some help from the more experienced among you in order to identify a broken diode that I found while working on a JVC integrated. The diode is D603 and is only marked in the service manual with a JVC part number and a manufacturer. Google had nothing to say about either one...

    Strange output transistor setup on JVC 4VN-880

    I am attempting to clean an extra-dirty JVC 4VN-880 (was used in a bar for 30 years). When I looked at how would I remove the output transistors, I found something I’m not familiar with: On the opposite heatsink side that the transistor is, there is a strange connector composed by two...

    Price check on JVC QL5 with Jelco arm

    Hello, I was looking around for a turntable and while buying a preamp the guy mentioned he was selling his prized TT. I didn’t get the specific arm model, but this dude is into some pretty high end stuff. Here’s some photos he texted me:

    JVC quadraphonic

    I have the opportunity of picking up a JVC 4VN-880 in good shape for around $200. I love its beefy looks and I’m not particularly interested in quadraphonic tech. Would it make a good stereo amp?

    Victor SX-3iii....bad tweeter

I'm now realizing I have a bad tweeter in one of the speakers and I'm wondering if its even possible to find a replacement. Anyone...

    Speakers connected to JVC AX-R97 get quiet when you turn on Rear (aka B or Remote Set)

    Long story short(ish), as soon as you turn on the secondary set of speakers on my JVC reciever, the primary speakers lose almost all mids and treble (sound muddy). I discovered this issue when attempting to add a sub with an integrated amp, but if you press the button to turn on the secondary...

    Hello again. I am still working on the JVC A-X9 and as the title indicates I have moved onto the lamps. After some searching through the forums I didn’t find any hints. The service manual also doesn’t offer any specs not the lamps (but it does show three different part numbers). However the...

    JVC TD-V621 Display

    The display on my awesome 3-head JVC cassette deck is really weak. It's a hair stronger on the left side than it is on the right, but it could all be brighter. Do I replace the display capacitor to repair this?
