Onkyo CP-5000A from a friend - good belt driven FG servo controlled deck, which means speed is regulated electronically and not by changimg belt position on 2 speed pulley. Has pitch control and strobe. Arm is a bit crude, but it is about average what was available on vintage Japanese TTs. No VTA adjustment. Sounds surprisingly nice with properly adjusted AT95e cart tracked at 1.9 gram (19 mN ).
This is a photo promised quite a while ago; first read about this/similar in The Absolutre Sound of the day, in review of Sumiko Analog Survival Kit - where something similr was included:
Here the close-ups of the "knots" that hold the stretched foam rubber string in place; NO glue whatsoever
Here the material "string" has been cut from with normal scissors - the usual foam rubber profile for stopping leaks in doors/windows:
Please note that whatever "glue/threads/etc" on the flat surface that is otherwise self adhesive mounted to door/window frame, must be removed for our purpose prior to mounting to the arm tube.
The purpose of this "string wrap" is to damp the resonances in the arm tube usually made from metal and sounding, you guessed it, quite metallic. Although it makes biggest sonical benefits with lower priced vintage gear, its use is by no means limited to those only. Some high mega zoot price designs also showed marked improvement(s). Without going too much into specifics, it will sound quieter in the groove than normal - and that alone is worth a lot.
It is very light, adding approx 0.6 gram change upon rebalancing the arm - do not forget to rebalance the arm and set the VTF you normally use. The string is wound under as high reasonable tension you can achieve/are still comfortable with. If arm has removable headshell,it is advisable to remove it. If the cartridge has GOOD STURDY stylus guard (not flip guard or anything possible to remove with light force ), you can use this. If you intend to try "string wrap" on some arm sporting unprotected nude naked cartridge named after bird with a hefty price tag - REMOVE IT FAR AWAY and remount only after your string is securely in place on the arm tube... Goes for ANY cartridge you mind demaging.
If your arm has sensitive bearings, it is necessary to remove tha arm from the table, apply the "string wrap", and then remount everything back together.
Please note that I do not assume any responsibiluty for your equipment - this is only general suggestion and you are on your own regarding implementation.
How can it sound? etc
