solid state

I've been a member for a few years now. I have read and learned a lot as a result. Now I want to share one of my projects. I bought this receiver from the Bay about three months ago and last week it stopped powering on. I diagnosed this as a switch fault but I had planned on doing a recap...

Hello all! Last summer a former work colleague of mine was relocating across country and decided to give me his old audio equipment for free- including a Marantz Model 140 power amp. After a little while I decided to locate a matching Model 3200 preamp to go with it and to assemble a nice solid...

Hi everyone! I'm in the process of setting up my first audio system, and I'm currently on the lookout for a good amplifier. I've narrowed down my options to three choices available in the second-hand market. Through my research on this forum and other websites, the Kenwood KA 4002a stands out as...

I have a Pioneer VSX-3600 receiver that is in good working order, but I need to replace some caps that are slightly bulging. I have the service manual with the schematics and part number list. However, the parts list does not show part values. Some of the components are hard to see without...

I plan to replace my current amp (Denon pma 600ne) with one of the two amps in the title because I no longer need all the functions that the Denon provides, e.g. DAC, BT, preamp etc, and I am looking for a pure power amp. I only need the amp to drive a bookshelf speaker, namely, Elac dbr 62 and...

Hello friends, first time posting here. Just getting into vintage audio within the last year or so and really enjoying it. I’ve got a Rega RP1(not vintage), a pioneer sx-1500td and a couple of Bose 301 Series II speakers. I’m supposed to be picking up a couple of late 70’s JBL L19’s this weekend...

I'm looking to hear about other enthusiasts' experience with hooking up amps and preamps from different series or different manufacturers etc, as opposed to the matching designated pair. I've heard good things about putting a tube preamp with a powerful solid state amplifier for instance...

Hello all, I recently picked up a low wattage (speaker is rated for 2 watts) amp on the verb, and it has a few issues. I think it needs a cap job, because after a few minutes of playing on higher volumes (so far higher volumes only) it starts humming and ring modulating. At low volumes it works...

Hello everyone, This week, I bought a Realistic MTA-15 table radio off the Goodwill site because it was cheap and I wanted a nice radio that might sound good and didn't have DSP, just for a change of pace. Like some things you buy at a thrift store, it can be a hit or miss proposition. No...

I have a spare Sansui 7070 I ordered from eBay quite a number of years ago. When it arrived the speaker selector switch was badly bent. UPS Insurance reimbursed the cost so it was free. After it sitting in the basement for 8 years or so I dug it out and fired it up yesterday and it works and...

Hi all I've got a well-loved but frequently-serviced MC2105. The current concern is that when it's powered on, I get some major speaker thump. Though it's just a single oscillation and my speakers are now pretty high power, they're now too expensive for me to risk damaging them from something...

From what I've seen, this thread has been done many times, so apologies right out the gate to beat a dead horse with so much information already out there. I recently bought a serviced SX-780 and am really pleased with it. I've been looking for proper speakers to pair with it, as I feel it...

See title. Is this normal ? And if not is it easy to solve? I would prefer keeping it as is as it was completely overhauled a few years ago. But since it's not mine I don't know if this has always been the case.

Lucky enough to pick up an old power amp for only $30. Guy said it was used for parties, events, etc. He said it turns on but he hasn't tried it with speakers so who knows. It's a Mosfet amp rated at 300 watts (per channel?) according to the label on it. Made by an Australian company called...

The radio of my R-2000 now suddenly doesn’t produce any sound anymore, just a very faint humming. Why all of a sudden? What’s the issue here?

Looking for a suggestion where to start on troubleshooting this. I bought restored, and it has been in the kitchen of shared office, working fine for a couple years. -- 1. Recently it stoppped working, was producing only distorted sound in one channel, other channel dead. 2. I checked fuses and...

Hey AK, I’ve caught the dreaded bug; upgrade fever. And I need your help with my ailment. I recently ‘upgraded’ my ADS L620’s to minty Canton CT-800’s and I’m extremely pleased, but now I’ve set my sights on my late 80’s Denon PMA-520. Should I keep it or ‘upgrade’… that is the existential...

So I am happy to say that I have two systems, both of which make me very happy: one is solid state, the other tube-based. I have a small office/guest room where I use this stuff, and I guess I would like to use the solid state for more contemporary stuff like Bruce Springsteen or Fleetwood Mac...

So I picked up a Sherwood s-7900 in beautiful cosmetic condition. Actually I picked up an entire carload of gear and after getting a pioneer sx-3700 and sx-780 sorted out(for the most part, still waiting on some final parts to fix a problem with the phono stage) and ordering some parts for the 2...

Hey guys! I recently purchased a Sansui AU-3900 and honestly for a solid state it surprised me how tube-like it is, however one of the transistors is messed up so it’s giving me static, crackle, and pops from the right channel. I spoke to the guy and he offered me to exchange it for the AU 217...

Hello, I have a question about an sx-780 I want to fix up. A little background on me, I've done some tube radios, both AM and one AM/FM. I'm familiar with basic soldering/desoldering, recapping, and limited troubleshooting. Use (in series) an isolation transformer, variac, and dim bulb tester...

last night i made a bit of an impulse decision and ordered some elac "sensible speaker cables." now that the gin has worn off, i realize these cables come with banana plugs on both ends. will i be able to connect these to my pioneer sx-850?

Hi! Anyone know where I can get a replacement for this turntable? It's a Magnavox Automatic 400. Thanks!

Hi AK, I hope to get some advice on amp choices For the last few years I've been very happily listening to a Sansui AU-666 (fully restored by TomB). Recently, I picked up a Luxman turntable that I am also extremely pleased with, in part because I think the styling is so beautiful. Ive since...

Hi all, i recently picked up a Grundig KS 732U solid state console with Turntable at the thrift store, it was powered up by another guy so i did some poking around and discovered no sound at all, light in the cab would come on but TT wouldn't power and couldn't even get static from the radio...
