Thanks.

Can't you find a CD of this performance? ;-)


"Keni Burke - Changes" - cost a few bob! Grr now you've made me spend
some more cash at Amazon marketplace :)

I had a similar turntable here in the past, and it seemed to transmit a
hell of a lot of motor noise to the stylus, may be the same for you. I
guess you have removed any trasit bolts on the TT?

I also have a couple of records that seem to have hum recorded into the
groove, but as this seems to be the case with several of your LP's I
guess thats not it.

May be worth checking with the place you got it from, there is no excuse
for any turntable to do this.

Strange - it's mainly hum which would suggest a ground problem,

stylus was lowered. It's possible to get induced hum on the
cartridge from the turntable motor which doesn't show with the
pickup on the rest.


Aren't you seeing the lf stuff?


Only listened to it on the computer speakers. The mains hum is the
obvious thing.


Ah. Look at it in a wave editor. There's HUGE amounts of lf rubbish.


As on any LP?

**No idea. I only test TTs at 33.33RPM, unless specifically directed to
do otherwise. I DID, however, fall into the trap of testing the Debut
into a phono preamp. Once. Are you absolutely certain yours does not
have a built-in phono preamp?


Have you listened to the clip? That's only gone through one stage of RIAA
equalisation. Also, feeding a line level into a second pre-amp would
result in *vast* distortion.

Could be a bit of hum and rumble mixed in together. No I haven't bothered
placing your samples into CEP and analysing them - too busy today for that.
Some records actually have some rumble evident from the master cutting
process. :-(


It took me probably less time to chuck the sample into Wavelab and
look at the spectrum than it did to type this message :-) If you're
going to comment, might as well take the trouble to look at the
problem.

Done. I've re-recorded the clip, and added another clip from another
vinyl source for good measure.

Note that the very low frequency repeats 33.3 times per minute on the LP
and 45 times a minute on the 45. Could be a dodgy bearing or two duff discs.

There may well be no earth anywhere, which is just as likely to cause mains hum
as two earths. You may need to add an earth.

**OK, first mistake: The Debut is already fitted with a phono preamp.
It
can only be used with a line level input.


**Oh yeah. Make certain the MC/MM switch is correctly set.


Hi Trevor, after a bit of Googling, it looks like you have the "Phono
Speedbox"
edition ??


**I don't own one, I just fix 'em. All of the Debuts I see are fitted with
an internal phono preamp.




Interesting. How many have you fixed??

If that was the case, I would expect the noise to be when the lump
passes over the pully, which would be less that 33.3 or 45.

** How is that so ????????

No matter what size the belt is, it only traverses the motor pully once per
table revolution.

Think it through .......
