Shoshani.... Get those red rubber connectors and you'll enjoy them. After fitting them... you'll want to replace all your black rubber ones!
Do some experiments and please, report us your impressions!
P.s. Are you the same Shoshani of the 78-L list of many years ago?

Inigo, might you be referring to the rubber backs as sold by this ebay seller? I am wanting to try this with my 5A sbx. Thank you.

Yes, those rubbers... But I think I bought them cheaper, sort of a complete set for something more than that.
Why don't you ask in this forum, wanted section?... I bought mine years ago, but 15 pounds for one still seems expensive...

I had a whole variety of rubber parts made a while back. Including rubber backs for Victor Orthophonic and the HMV 5 series They are for sale here:
http://www.gramophonemuseum.com/for-sale.html
They are £15 each for members of this forum.
with aid of a bit of water or vaseline added to the inside of the rubber
I tend to use talcum powder.

Indeed, I am! Still on that list, too.

I've been looking at this, trying to figure out what I need for this project. Probably a Type C and a Type H, possibly a Type F. All, of course, after postage resumes outside Australia... (I have purchased a brass - yes, brass! - HMV 5A/5B back, which does not have the isolator and ring. It might be perfect for using the same soundbox on my HMV 102 and HMV 101 by just switching out the rubber back. Something I wouldn't dare do with a pot metal back, for fear of putting undue stress on it.)

Hello there! I can certainly recommend the EMG rubber tone arm insulator as an improvement in an His Master's Voice 5a or b. I always felt the rubber gets too hard after all the years, and the flexibility of a new rubber back insulator is well worth the expense-and much kinder to gramophone records, ie less wear.
I have never understood why a special compressed felt was used instead of the conventional rubber gaskets on the re-entrant sound boxes. Surely the felt must get damp over many years, and effects on reproduction might lessen. This is my opinion. I have in the past, taken a 5a or a 5b, and placed it in a warm conservatory for one or two days, then placed it immediately on the tone arm of the machine. I am sure that I have noticed an improvement generally in reproduction. Perhaps one or two of you have tried this...?
