I am facing an issue with my turntable. It seams that the headshell is not fucntioning properly. I only get left channel audio and I get a low hum from the other side. If I touch the wires attached to the headshell going to the right channel then they are very touchy, sometimes they stop humming...
Hey guys, so I got a Marantz 2230 from a guy to do a rebuild of the audio path.
So far when testing I've noticed that one channel has much more bass than the other. It's made worse by the bass potentiometer which leads me to believe that it's a preamp issue.
Could it be the 2SC1000s in the...
Hey all, I have a Sanyo TP 625 in great shape. Small speed issue, plays a bit too slow. Just wondering if I bought a project primary, would it be an upgrade or a lateral move? Thanks for the help!
We just recently bought our first vintage turntable (PL-518) and my son while changing a record inadvertently hit the stylus knocking it out of center. I moved it back by sight and while it still plays music it clearly does not sound quite as good. It is especially noticeable between songs...
So, I picked up a Sansui FR-3080 from the thrift store. Everything seems okay but there's one strange problem: when it auto-returns at the end of the record, the tonearm lifter doesn't come up in time. The tonearm does the returning, but it drags across the record for a few seconds before the...
Hey guys, so this is the same amplifer but a new issue arose...
I got both of the back channels working after giving PE01 a full rebuild, however now my front left preamp channel isn't working (yes I tested crossing wires). I know the amplifer channel is good.
My voltages on that channel in...
Hey guys, so following a recap my SX-434s FM board seems out if wack.
The tuning needle, when I'm FM mode appears to be working as if it were in the AM setting. The needle won't deflect past the center point. Then, if FM muting is turned on/off there is a pop. When muting is turned off I get...
Hello, quite new to this whole thing. I have an old Phillips turntable and a broken flip needle that needs replacing. On the one side it has an 'ST' and on the other a '78HC3'. The turntable is a Phillips AG-4656. Any help would be much appreciated!
Hello, everyone.
I recently found a Toshiba SA-750 for sale, and, having never really seen a Toshiba receiver, I was quite taken by it, and found it amusing that it appears Toshiba looked at the Pioneer SX-750 and went "yeah, that'll do, but can we put the volume control where Technics puts...
Hello AK'ers.
I retored my 2270. SN 38510. BASES ON THE SUPER POST from @Leestereo and recently @Super Noob .
All is fine except LEFT amplifier ( P750, LEFT)
After all the new parts installed, BIAS is about 2.1-2.3 mV, i know it should be 10mV.
I changed diff transistors, pre drivers...
I'm not sure where to put this so I'm going to put it here and hope for the best. I recently acquired a BSR MCD8050 CD/Cassette combo. It won't do anything when I press any of the buttons. All the belts and stuff inside are good. I'm stumped. Please help!
Hello AK'ers
A friend is selling me a PANAMAX M5300ex, good shape, it turns on BUT have the problems shown in the pics....
the price is very very low (compared with a new equipment) but i can't find diagrams about the line conditioner
does it worth to repair?
anyone with a diagram of it...
This one might be hard to explain, but I'm gonna try my best.
Recently, I acquired a JVC JL-F30 fully-automatic turntable. The only big problem it had initially was that the arm raising assembly was completely broken. Since then, some new problems have come up. They are as follows:
When I try...
The seller claims it's a kiseki red cartridge however a google search for that name comes up basically empty. The box does definitely look like a kiseki box though so I was wondering if any of you know what cart this is
Hi, I have a Spec-1 and the left channel is low. I've been looking at the schematics for the amp and just can't seem to locate some good interim probe points to connect my Oscilloscope to to try and isolate the location of the issue.
It seems to me that there is a transistor that has failed...
so I just got saved this Pioneer SX-680 from getting pitched at the dump. the guy who had it was the first and only owner. i brought it home and put a 4ohm RCA speaker on it and a variety of other speakers (up to 4 ohm) and none of them worked in any of the different outputs. everything seems to...
Hello,
I recently purchased a used McIntosh MC275 IV amp, and upon hooking it up I noticed distortion on one channel right away, seems to get louder as the volume goes up. The whole unit is not as clear or as good as i expected it to be.
I have swapped the original McIntosh KT88 tubes and the...
Hey everyone, hope everyone is staying cool this July. Just ordered an Eico Hf-81 and was wondering is anyones noticed that there seems to be two versions of the output transformers, anyone know if there is a quality difference? Also any idea of new pots to replace the old tone controls? Really...
Hello
I am new to this site I just recently picked up a unit with a record player and radio on it the components inside are electrohome units and on the front is a logo with a black T. I am hoping to get some more info on the unit as it is in really good shape. I haven't tried the turntable yet...
Hey guys, so this 2252 is just a bundle of surprises. After putting it back together, the AM section seems to have gone silent on me no static, get the occasional pop if I poke the AM antenna connector at the back. Any ideas where to look? It's not a huge deal since where I am located pretty...
I just picked up a really nice, clean SL-D5 turntable, with BOTH spindles. This has been taken care of well, It looks like it's worth the effort. Dust cover is in good condition, clean etc. etc. I was excited, but the seller warned me that there was a speed control issue. I thought, no problem...
Hey all. I have this Marantz model 1030 amplifier with some problems.
Problem 1: Left channel has extreme distortion under any kind of load. If you crank the bass control, it distorts to hell and gone.
Problem 2: When attempting to set the bias voltage for the left channel, it's ENTIRELY too...
Hey guys, so I have a 2252 that gives me a large thud, and significant DC through the speakers on shut down. The amp Powers up just fine, no thuds and typically the relay opens within the expected 5 seconds or so. On power down the relay seems to take much longer to close, to the point where I...
Hey guys, so this 2225 is giving me a fit, now it seems that the AM output isn't working. When switched over to AM voltages seem to be checking out on the AM board, the only thing off was pin 13 on the H104 chip pin 13 had 0v rather than the expected 1.4v.
Not quite sure where to go from here...
I picked up a Sanyo TP-1012 at a thrift store today and am having the following problems:
Tonearm will not lift during auto return. I can lift it manually just fine.
Tonearm lifter has lost dampening.
Warped platter. Not sure if there is a real fix to this, but I thought I'd make it known...
