The one with the triangle design was made by HMV and is normally found in the 5B. Sound wise there is not a difference.<br /><br />Victor used paper gaskets coated with what looks like varnish, HMV used felt gaskets which sound bad. The diaphragm was designed to be clamped firmly in place. Replacing the felt with neoprene rubber vastly improves the sound. I have 5A's, 5B's, and the regular Victor Orthophonic and suitcase models with the cover on the front.<br /><br />The other difference between the Victor 5 and the HMV 5's is the needle bar pivot design on the HMV is far easier to work on. On the No 4 and No 5 make sure the needle bar moves freely, I had one No 4 the one pivot was slightly over sized and the bar did not move freely and the sound was poor.Steve Mhttps://www.blogger.com/profile/03502289801575168084noreply@blogger.comtag:blogger.com,1999:blog-2910442227111579556.post-17305681565768444272011-09-08T18:22:11.349-07:002011-09-08T18:22:11.349-07:00i have replied to your email, nice to hear from so...i have replied to your email, nice to hear from someone interested in gramophones too!Phttps://www.blogger.com/profile/17427400099499231600noreply@blogger.comtag:blogger.com,1999:blog-2910442227111579556.post-23744616552945572062011-09-07T19:07:50.066-07:002011-09-07T19:07:50.066-07:00Hi!

P,<br />The diaphragm which u got it from Ken, is mend for the 5A HMV Soundbox.<br />It must be very costly for u!<br />Does he not have any diaphragm for the 5B model?<br />I used to deal with him. And he is a friendly & helpful guy.<br />I have undertake the same project as u do in the past.<br />Do u change the pair of gaskets? Don't used the old ones. U may keep them.<br />I have tried changing the followings on my Soundbox as well:-<br />1. Rubber bushing for the tone arm connector.<br />2. The pair of gasket.<br />3. Replace the old stiff stylus needle bar (which is often rusty).<br />4. Try looking for the correct diaphragm. And is going to cost me alot which I find not worth it on ebay. Instead salvage from another old soundbox.<br />U collect gramophone as well?<br />I can be reach at sengchee.chia@pacific.net.sg<br />& we can discuss more about it.<br />Thanks!<br />Rgds,<br />CheeAnonymousnoreply@blogger.com
