help

Hello to everyone smarter than me! I'm needing the help of the community. I have a 1960s Magnavox Stereo with working turntable, reel to reel, and the option to send the audio to external speakers. The back has screw terminals posts. How would you connect this to a pair of external speakers...

Hey guys, this is my first post and I'm not really all that great at rebuilding amps yet. I was wondering if anyone could help me with my problem. I have no real history of the amp other than it was in a barn with its top and bottom off, and had a mouse nest that had mouse chewed wires in...

Hi ! Just finished a overhaul of a TC-399 i just acquired, took it all apart and lubed everything, changed the belts, cleaned monitor switches, pots, idler wheel, heads, captsan and pincher wheel (all cleaning was done using Isopropanol alcohol). Mechanically it works great ! Only problem...

Hello everybody! My name is Frank and I live in Florida. Brand new to the site and I need some help. I have a Kenwood rack system that I probably bought between 1989 and 1992. Up until last week, the system still kicked ass! Now, it seems my amp (KM-209) is having issues. It will play for a bit...

Can’t find a pinch adjustment anywhere (I heard) there isn’t a pitch adjustment. I’ve bought a new belt and oiled the hell out of the thing. Any help here? Would really like to get this thing running back to speed. *wink*

Hello AKérs I´m really curious about using a vintage unit ONLY to listen it with headphones. Is it a good idea? Could the long term use of headphones damage a vintage unit? A friend on mine (not suscribed to this forum) asked about this. what i know: headphones in the unit are only for...

Hi all, Have a pioneer sx2500 on fantastic cosmetic condition that plays wonderfully when working properly. However, it has intermittent problems with both channels on all inputs. I figure that since it’s on all channels problem likely lies in the main amp unit or protection unit (AWM-004 in my...

Hi AK, This is my first post on here and I have to thank you all for all the valuable information on here. Such an amazing community. Without it, I would never think of taking on a project like this since this is not my field. I picked up a Pioneer SX-1010 a couple of months ago. I live in...

Hello AK, I'm a bit of a noob to world of Hi-Fi. I started building my system about a year ago now. My brother-in-law gave me a JVC XL-FZ258 5-disc changer he picked up from an employer. It didn't look like it had ever been used, the price was right (free!) and it has proved to be a...

Hi guys, this is my first post here and I hope you guys can help me. I have a Marantz PM6006 that I've only been using for about two years. A while back it suddenly went into protection mode while playing and ever since it's gotten worse and worse until now: it just turns off right after the...

So long story short, I have a tube headphone amp that I had a technician recap recently. Set it up on my desk to test it out and first thing I noticed was loud, erratic noise coming out the left channel that would fade in and out intermittently. This settled down after some testing and tube...

Hello all, I just finished a repair of my SX550 I got for $25. After replacing some caps in the power supply, new LED lights, cleaning the pots and setting the bias it sounds pretty good! I am very happy with its turnout. I am having two persistent problems though, on startup there is a loud...

Hello AKer´s. I recently start the SX1050 restoration. Unit was DOA, and it had several problems.. i show some of them : AWR-104 power supply was broken, i fixed it with epoxy, patience and soldering wires point to point on the back of the PCB. on AWM-090 protecion some resistors was...

Hello there, (I hope I put this in the right place on this forum) I got a Sony TC 377 Reel to Reel tape machine recently, it spins fine, and I can FF, reverse and change speeds with no problems, but when monitoring the tape, there is an extremely loud hissing noise which makes the tape...

The "up / down" switch on my PS-48 will raise and lower the tonearm lift just fine, but the lift itself sits too low and won't adjust higher and I'm not sure why. I unscrewed the hex screw in the tonearm lift like the service manual said, but the lift still wont extend higher. Could it be that...

Hey everybody, so I’ve got a rather strange problem and I’m not sure if it’s a speaker problem or an integrated amp problem. The setup I’ve got a beautiful pair of Polk SRS SDA 3.1s (with the SDA cord connecting them), a Kenwood KA-3500 integrated amplifier powering them, and a kenwood ss-79...

Hi all, have an otherwise well functioning pioneer QX-949 and am just now getting around to setting it up with a turntable and I’ve stumbled into a problem. The AUX input works perfectly; however when playing AM/FM radio or through either phono input with the turntable, there is no bass coming...

May have the opportunity to trade my up to spec pioneer sx-1010 for a dynaco pas3, st 70, and an fm-3 plus a little cash on my end I could really care less on the tuner. So that’s not a plus to me in anyway. But I have been very curious of tube separates lately. I’m running Cornwalls with the sx...

Hello AKers I am working on a 9090 unit, previosly not-so-good repaired. After recap and resolder al the bad joints, i still having the problem before i treated the unit: Sound come and go with some volume, more that 25% volumen and the unit behave as in the video...

I picked up a sansui eight and a sansui 800 amongst some other solid cassette decks that “need belts” one being a tandberg all for $50 all the decks powered on and buttons were functional but the receivers are a different story. They were possibly rained on, the 800 I’m almost positive has had a...

So I have a tps l2 that's almost completely working again but suddenly the microphone stopped working. The only thing it picks up is if I blow into it or if i tap the microphone. I measured the resistance over the wires and on the connection on the board but all seem to be fine. I assume the...

Hi Everyone, I have found a lot of info on this integrated amp in these forums, and am especially impressed with Leestereo's refurbishment of Scribby31's unit several years ago. I still have one of these and while it probably needs a similar recapping and transistor upgrade, I have a more...

Hello Audio Karma Forum, I am in need of some help. I am new to cassettes and music as a whole. I recently purchased a tape deck (Yamaha KX-332) in standard used condition and it works fine until when I was recording, I now hear a loud screeching noise that fades in and out. I have diagnosed...

I have read these forums for years as I have shuffled gear in and out of the house, this is my first post. Picked up a pair of rectilinear mini iii recently in amazing shape but they clearly need to be recapped as the mid -- high adjustment need to be all the way up to get much of either I...

I've been using my headphones with my amp for a while and want to finally get some speakers. My amp is the Denon PMA-860(80w 8Ω) and I'm using it with a Topping D10S Mini connected to my PC and a WEGA JPS-350P record player. (Planning to add a Denon DRM - 800 sometime later) I'm living in a...
