One man's opinions here ...

I've had pretty good luck with old grooved media (78's and early LP's) as far as ticks and pops by 
focusing on deep-cleaning the disks first and foremost. I've been surprised to find that except for 
badly damaged disks, 78's are not as prone to constant and annoying ticks and pops as vinyl. I don't 
mess with badly damaged disks of either type unless they are highly unique -- usually, given that my 
time messing with them has a monetary value, it is more cost-effective to find a better-condition 
specimen. However, in those few cases where I've had very problematic disks, as long as I can keep 
the needle in the groove I still find that, by a very great amount, the best fix for ticks and pops 
as far as audibility is the tried and true manually-fix method. In Sony Soundforge, practice and 
experience have taught me to zoom in on the ticks and pops and repaint the waveform using the pencil 
tool. Practice teaches you how to do this for barely audible or inaudible results. This is as 
time-consuming a method as exists except perhaps editing out microseconds with a blade and splicing 
tape (done that, hope to never do that again). But, the results can be superb if you use experience, 
learning and your ears to shoot for removal with no new artifacts.

As for non-badly-damaged disks, my own taste is to put up with some crackle and a few low-level 
ticks and pops. Why try and mitigate what's inherent to the medium? If I make a transfer, of course 
I'll go in and manually fix the few big ticks and pops, but not go in and grab every little 
disk-noise thing.

As far as feeding the Packburn, has anyone tried a flat-with-gain preamplifier, then feed the output 
of the Packburn thru an appropriate EQ filter, either as a piece of analog gear or in the computer? 
I would think, with no EQ, the Packburn would have the best shot at NR, but I might be wrong on 
that. Plan B would be to make sure and use the appropriate phono-preamp curve before the Packburn, 
so it is getting the intended frequency spectrum to work on. Then adjust for minimum artifacts and 
be satisfied that what you're hearing is as good as you're going to get out of that chain of 
equipment and stop worrying about it.

But, circling back to my first point, starting with thorough cleaning of the grooved media has 
always been my strongest ally in either a good transfer or a pleasant listening experience, or both.

HI Again!

May it be an idea to take the signal from the Packburn into a paramertic
equaliser and try to reduce some of the surface noise that way??

Hope to hear from you...

Best regards

Hi everybody,

Jan Myren described his Packburn setup and seems quite satisfied. I did not
know that it had an "undo RIAA" feature in its later versions, but I assure
you that the Packburn switcher works even better if the treble is not rolled

of like RIAA does.

In cooperation with John R.T. Davies Ted Kendall has developed what they
used
to call "the Mousetrap" that used components that were 25 years younger than

those of Packard and Burns, although the basic switcher idea was the same. I

do not know whether that is incorporated in Ted's "the Front End"
preamplifier that has many useful features. It is only built to order.

Jan asked:

----- if I remember correctly, Robert Parker artificially boosted the high
frequencies by generating distortion by having an elliptical stylus with the

long axis along the groove. This permitted/indeed REQUIRED very heavy treble

filtering to remove the distortion (and any noise from 78s), so that he had
a
lot of fundamentals. Any lack of brilliance was counteracted by heavy
reverb.
All in all disgusting results, but John R.T. was forgiving: "it will
advertise that there is plenty of interesting material in these old records,

and those who want to engross themselves will go to the sources".
