Turntable nerds... help

Postby Gramsci on Tue Aug 20, 2013 3:49 pm

This came with my Dual CS505-4. It's a alternative counterweight...?

It's a CS4xx TT1...anyone know how to fit it...?

Just set it for whatever f-stop is appropriate for the ambient lighting, and make sure to set it for whatever mains voltage your country uses. Your bacon will be cooked to perfection!

Isn't this an extra counter weight that you add if you need it (for heavier cartridges?)

It starts at 2.5 which is already pretty heavy. The Denon DL103 tracks at 2.5 but most modern carts track at 1.5-2.0 range. I don't think you'll need it. What cart do you have mounted?

It's hard to find info on your TT but I saw a forum post saying some of the DD duals had a port on the back of the tonearm where the extra counterweight is added. I think you look on the back and see if there is a way to remove the back and insert the weight.

Hey guys,

Thanks! Great lead. From I did some extra sniffing with this info and yes, it's an extra counterweight for heavier cartridges. It's rather nicer to look at then the original so it's kind of a shame it's not an "upgrade".

Thanks again.

Yo dudes -

I have an Audio Technica LP120 (the Technics 1200 clone,) and suddenly I'm not hearing anything out of the right channel.

When I play CDs, I hear equally out of both channels, so it's definitely a record player thing.

Does anyone know what this is?

My wife confessed to me that she recently let the fucker spin all day on a label when she forgot to turn it off before leaving the house.

Would that have had a negative impact?

I'm also noticing there's an inordinate amount of noise on the outer groove (i.e. the moment or two before the first song on the side kicks in,) and there didn't used to be.

Are these problems related?

I'd start by flipping the L-R phono inputs.

The issue could be in your receiver's phono stage or the turntable. If the right channel kicks in when you flip the plugs, your TT is fine and the receiver's right channel is the problem. You should also try a few different LPs.

I doubt your wife's to blame. That sort of thing can degrade your stylus, but I doubt it would knock out one of the channels completely.

I have a Technics SL 1500 which was operating well until recently. After a year of not using it, it will not turn on. My only guess is a fuse but I have never dealt with this problem before. This is my first turntable and I don't know if i'm better off replacing it. I would love to restore this is possible. To me this is great turntable

does it do anything (strobe light etc.)? first guess would be the fuse, or a mechanic defect of the "tonearm on-switch" (whatever they're called), or maybe a bad capacitor on the circuit board

Many of the Technics turntables from that era have a circuit board under the platter, and on that board there are fuses that sometimes blow. This might help.

I have an SL 1500 MK2 that works great, the sticker on the platter says "Don't remove the platter if you don't have to, it's part of the motor you bastard" etc., so I never removed it.

Marantz 6300: micro-switches

Postby Bubber on Sat Dec 23, 2017 7:13 pm

Hiya. Anybody ever swap out the micro-switches in a Marantz 6300? I really like the turntable but it's been out of commission for a few years. I can get switches in good condition to replace the corroded ones, but the tech down the street says it's time consuming to swap `em out and he doesn't want to do it. Any sage advice?

Well, it seems like we're all having issues w/ our turntables. Here is mine:
Technics SL1600- sounds great. Got it and my KEF K series speakers and 90's Yamaha receiver in trade for a junk guitar. However, the turntable has never worked properly. The start/stop feature is non functional-it will simply pick up the tone arm, send it all the way to the middle, click, then bring it back, set it down and turn off. Same thing happens when you pick up the toe arm to do it manually. The first record of the night I typically have to pick up and move the tome arm around, back and forth a few times...then it will work manually. I assume this is a 'Take it to the stereo doctor' situation.

you can take the platter apart and just disable the tonearm mover thing. there is likely an arm connected to the tonearm assembly and a system of pins and gears that, when triggered, is supposed to move the tonearm back to the resting position. I would just disconnect all that noise.

oh you want your tonearm to return to the resting position and the table to stop rotating? I bet once you get the platter off you can see what is wrong. it will be simple and obvious.

Perhaps not a fuse if it's just been sitting idle. If the fuse has blown it's often an indication something else has gone wrong. It may be that a rust spot has corroded one of your circuit traces or something dumb like that. But check the fuses first...

Things that don't turn on at all are often the simplest things to fix as it's probably just not getting power. If it's not fuses, then what you do next depends on whether you're the sort of person who owns a multimeter.

I would say there's a high probability it can be repaired and probably quite easily. The next thing to do is check the power supply is working correctly, and then work your way back from there.
