Don't worry about the price.  I will mail out the stuff Monday Tuesday at the 
latest.

Charlie, 	

No, I do not have a fast connection. Still happy with my 56K modem service. I 
am
good in qrz.com 	
I would very much appreciate having copies of the information you mentioned.
Please let me know the reproduction and postage costs. Thank you very much.

If you have a hi-speed connection I can scan some stuff on curves for you and 
email them.  If not I can xerox and snail mail them to you.
One way to compensate is to put an equalizer in the tape loop.  One problem 
arises with the phono preamp.  Since it is set for the standard RIAA curve the 
equalizer has to be set differently than the curves for the old records.  In 
short you have to cancel the RIAA curve and at the same time add the other 
curve.
Another way is to build a preamp into the equalizer but have the equalizer with 
a totally flat response and simply set the equalizer to old curve of the record 
in use.
The info I have has a real decent tube preamp project that covers all the 
curves and is worth looking at.  The filter networks themselves are also shown.
The total pages are maybe 10-15 or so.

Charlie, 	
1.	No, all of my systems are dedicated. I hate cable! The entire stereo system 
is music, no TV or anything else run through it. It is a little sound studio.	
2.	The vintage stereo system, the H. Scott, is dedicated as well. It has its 
own speaker system.	
3.	The surround sound system is also just for the Pioneer big screen TV, only 
Laser Disks and DVD and VHS run through it.	
4.	The Pioneer has its own Sony DSS system, as does the one in the bedroom. 	
5.	A good point on recording vinyl that was recorded as mono. I need to do 
precisely what you suggested. I seldom record from a mono vinyl album, but 
every now and then I do. I have done so with hundreds of 45 rpm singles. Most 
were remastered, so I got away with it. 	
6.	I am not sure what, if anything, one can do about the different equalization 
curves used in the forties and fifties. Somebody must have solved this issue. 
 The National Library of Congress, for example. They are busily working on the 
"Save Our Sound" project, and many of those recordings are on reel to reel 
tape, vinyl and even cylinders. Wonder how they got around this?

I use a stand alone deck for my conversions.  I have only 2 bits of advice.
If you have a cable converter connected to the same setup you use for recording 
disconnect it from the system,  If you like to watch cable while recording use 
a different amp.  In my setup there was low hum levels in the recordings after 
much work it was traced to the cable digital box.  Nothing more than a ground 
loop.
If you do a lot of mono recordings get another cartridge and head and wire it 
for mono.  The recordings will sound better.
If you do any recording of material from 1947 to around 1955 remember that 
these recordings use a different equalization curve than the ones after 1955 of 
so.  As a matter of fact there were 10 or so different equalizations used 
during the early days.

Greetings All, 	

This is a little too new, but still old, so pardon the stretch. 	
I have been converting vinyl 33 1/3 rpm records to CD format without a 
computer.
I have had extremely good success. However, this procedure is tedious, time 
consuming and requires a DAT deck. 	
Are any of you using a stand alone CDR deck wired direct to the primary sound 
system? 	
Here is one little trick that may help some of you salvage an otherwise 
unrecoverable recording. If a vinyl record has a scratch on it causing the 
stylus to stick, put a tiny drop of water on it. Let it expand and fill the 
grooves. many times this will allow the stylus to track through the area 
without sticking. However, there may be some noise, as the scratch is still 
there. 	
I use an outboard graphic equalization unit to minimize specific frequencies 
when recording the vinyl to DAT or CD. Many times you can eliminate, or greatly 
reduce, the noise present from heavy play wear, minor scratches and so forth. 
 Keeping in mind, that the depth to which the needle went, and the width of the 
grooves, has changed over the years.
