Meanwhile, I am SERIOUSLY looking for fifties/sixties/(et al?) "record
players" which
offer the "78" speed! You see, these usually use ceramic cartridges...whose
output
signal is around 1 volt...meaning that I can redirect the cartridge output,
using a
newly-installed "mini phono plug," into the "Line In jack of my sound card!
I did this for MANY years...I used a late-fifties RCA Victor "record player"
(which
I found in the neighbourhood "trash!"), with the cartridge o/p fed into the
"Lone
In" jack of a sixties Sony r2r deck (it functioned as the "heart" of my
sound
system then...!).
I just bought the n8-3d diamond 3-mil 78 needle which I need, to play my
c. 56500 78's...!
All the lightweight players (tracking pressue c. 1 gram?!) have always
seemed to me to be MUCH better at picking up surface noise than
actual content...!!
