Hi Andy,

APSCO's loud tone needles continue to be a tried and proven item for my
personal use and sales from my shop. I am not much of a fan of soft tone
needles at all. I would estimate that APSCO's loud tone needles are, as Ron
pointed out, virtually identical to early old stock Victor parts. Their soft
tone needles are also like original Victor parts. The quality of their
manufacturing has been constant in my experience. The only steel needles
that I prefer more than the loud tone are the early Victor extra loud tone
needles, but to my knowledge, no one is reproducing them. APSCO's needles
are made from common carbon steel rod. I suppose that anyone should
theoretically be able to manufacture them as long as their processes are
consistent. I have never had a defective needle from APSCO. That is, the
needles are always uniformly machined and are never characterized by the
presence of excess metal or poorly ground ends.

The white gasket material that APSCO supplies (the same as Ron S and a few
other folks out there) is like the original Victor material. It is natural
white rubber, but I suspect that the modern chemistry now used may be more
durable than the original Victor rubber. The dimensions of the tubing
(inside and outside diameters) are right on the money. I have also used the
tubing that Dwayne Wyatt's Musical Americana sells. I do not know the
precise chemical composition of the white gasket material that Dwayne has,
but it is definitely synthetic and I am convinced it has a significantly
higher durometer. Dimensionally, the two are identical, but the synthetic
material is more difficult to compress. But the effect of that difficulty is
that once the reproducer's castings are secured, I can achieve much tighter
clamping of the diaphragm edges which translates into noticeably better
frequency response. It is noticeable to me, but I don't think that most
people would really care to discern the difference - both are very good.
Although I have not tested nor compared the durometer of either APSCO's or
Dwayne's gasket material, I personally prefer the material that Dwayne sells
because I can achieve the tighter clamping. I have also used both types on
an innumerable variety of reproducers. My opinion is that the larger the
diaphragm (say, like a big Pathe Concert reproducer) the stiffer I prefer
the gasket, especially when it comes to the types where the front gasket is
merely seated against the inner rim of the front casting.

On the subject of the No.2 gaskets, without question, I think that APSCO
generally supplies the superior part. The durometer of them seems right on
the button - not too hard, not too soft, but you do have to deal with two
halves unlike the originals (and I do not know of any makers of such a part
either). I have not ordered any of these from Dwayne because most of the
parts I have received from APSCO are fantastic. Sometimes APSCO will send me
a bundle that have become out of round because of how they were
stored/shipped, but a pot of boiling water and a quick dip generally gets
them back to a nice circle. But, it is rare that I have ever had to mess
with doing that. The other variety of gaskets for the No.2 that are out
there, are, in my estimation, a bit too flaccid. APSCO's gaskets are again,
natural rubber. But one of the other materials that I have seen used is a
closed cell sponge rubber product. I do not know for sure if the material is
neoprene or blended with nitrile, but I suspect it is pure neoprene polymer.
They seal very well, but because their durometer is much lower than the
rubber the diaphragm seems to float rather than have a nice tight pinching
of its circumference. I might be splitting hairs to try to insist that one
is better than the other, but for my money, I like the APSCO material
because it is very much like an original part.

I don't know if you had a desire to know about any of the black and/or fiber
gaskets for other reproducers, but if you do, let me know...For now though,
I need to get some shut-eye. Also, be careful if you buy new diaphragms.

Hi All ~

I'm hoping to tap into your vast collective experience to guide me on  
my next purchases of restoration supplies.  I've bought from a couple  
of different suppliers over time, but have never made a quality  
comparison of new steel needles and also gaskets for rebuilding  
reproducers.  Specifically, the white rubber tubing for Victor  
Exhibitions, Brunswick reproducers with mica diaphragms, etc., and  
also the red rubber gaskets for the Victor #2 (I need a new mica for  
this one as well).  The red rubber gaskets I've purchased in the past  
are used in pairs unlike the one piece originals, and look like  
something available at a plumbing supply, although I've never looked  
for them outside of phono parts suppliers.

I would greatly appreciate any guidance anyone can offer on where to  
buy the best quality new steel needles as well as these gaskets /  
gasket materials.  Please reply to this at phono-l or off list if  
preferred, at [email protected]

Thanks in advance for any insights.

Andy
