Marantz 7 and Marantz 1 tube sub-chassis rubber mounts.  Auction is for 1 set consisting of 3 brand new USA made natural rubber isolation mounts/shock absorber cushions, these will last many, many years. They are the perfect replacement for the 50+ year old mounts that have probably already failed (see pics, 2nd image).  These mounts will allow the tube sub-chassis suspension to float properly and to keep the chassis as free from microphonics as possible.  They're fairly easy to install, takes less than 30 minutes.  

Shipping is $3.50 First Class mail in the USA. Will combine shipping. Thank you.
If you are overseas and need more than one set, please contact me and let me know how many sets you need, I will make a special listing. This will save you a lot of money on shipping.
