NEW Victor Victrola No.4 Reproducer SOFT Rubber Tone Arm Isolator / Rear Insert

Description

NEW DESIGN - Victor No.4/4A Victrola Soundbox-Reproducer
Rubber Tone Arm Isolator with Brass Insert !
Ready To Install - Superior Performance
(Reproducers shown in pictures are for example only and are not included.)
Most Victor and HMV No.4 and No.4A reproducers in original condition require replacement of this gasket because most of them are as hard as a rock. Old original isolators are actually very easy to replace and do not require any special tools. Careful use of a simple heat gun set to low or hairdryer is all you need to warm, soften and then remove the old isolator in. We have safely removed thousands of isolators this way. NEVER use a torch as a heat source. The flame tip of a torch is much too hot and may severely damage your casting, especially if it is pot metal.
We designed this isolator in our shop and we make them right here. The rubber compound that we use is very soft (durometer approx 35A-40A) and will last forever. Our design not only outperforms bench injected goo wads, but it is of higher quality construction and has the professional appearance of an genuinely engineered original part. We use recycled original brass inserts when possible to retain a sense of antiquity. If your reproducer is missing its isolator or if it has hardened or become mushy, this is what you need. If you have a bench injected goo wad all you need to do is pluck it out (easy to do).
This isolator is installed into the rear flange on the back of your reproducer and is held in place using two set screws. It is designed to perfectly fit the Victor No.4 and 4A as well as the HMV 4 and others. Please note that the HMV may require an additional setscrew in order to mount this isolator. Ask questions is you have an HMV! The inside diameter (i.e. the brass portion) is designed to mount exclusively on (smaller diameter) pre-Orthophonic tone arms. These will NOT fit an Orthophonic tone arm.
Ask questions is you need help and do not assume anything.
Important Tip: A hardened or mushy rubber isolator, although it may still mount to your reproducer and seem to hang in there, not only reduces the performance of the reproducer but it is also hazardous to your records. The hardness of a rubber or other material is often specified using a parameter known as "durometer". During play, a good rubber flange, in part, helps the reproducer track the groove by absorbing some of the energy caused by inefficient needle and diaphragm movement during record play. When the rubber has either become hardened (durometer is too high) or mushy (durometer is too low) the flange cannot efficiently do its job. If it is too hard, then the vibrations caused by the needle during play cannot be dampened, tracking is poor, and because of the mass of the large tone arm, vibrations are ultimately transmitted back to the needle tip where they inflict damage (cut) in the groove walls. If the rubber is too soft, excessive movement of the reproducer body (tilting) results which not only causes poor tracking but also damages the groove walls. We figured it all out so you don't have to!
Please observe the quality of the parts that we are selling. Even though you may be happy to just find anything that seems like it will work because yours is missing or busted, take a minute and examine what you are buying.
