Rebuilding rubber idler wheels

Those of us interested in the somewhat later 3-speed record player type machines have probably faced the issue of vulcanised idler wheels - where the rubber has gone rock hard. Some years ago I used a company in USA that did good work - http://turntablebasics.com/idlerwheels.html I tried them again ...

Re: HMV early radiograms

Thanks! Would be most interested to see it. Overseas versions seemed to have different model numbering, but I don't know if they were different inside. I somehow doubt that HMV Australia designed their own machines, but they might have done so.

Re: HMV early radiograms

They are a modification. One is for motor on/off, as the original tone arm/pickup arm and auto-stop are missing, the other for main power on/off. The other 551 is much more original.
Will see if I can record it shortly. Bear with me!

Re: HMV early radiograms

I have written a fairly extensive article on the first attempts to play 78 records electrically. Turns out it was Brunswick by a short head. Would I be able to upload it on TMF Archive area? It is about 11 MB in size with many illustrations. That would be great - I am sure the moderator will pick u...

Re: HMV early radiograms

No 473 is probably earlier than No 63. The metal label with 'For spares quote' was used in 1929, although it does not usually have a serial number on acoustic models. The circular ivorine label with a long number with lots of 0s in the middle came in some time in 1930. HMV changed their serial numb...

Re: Gramophone without brand: mysterious model 102... Help m

Hi Undoubtedly the circular 102 disc is from an HMV 102. If the motor were from a 102 the winding handle would slope upwards (a portable HMV has very little depth and there would not be enough room to get your hand around the winding handle unless it sloped upwards!). The soundbox is German (says so...

Re: HMV ID

Very similar to the inside of the HMV 551. Uses the very latest PX4 output valve, only introduced in 1929, so slightly later than the 551, which uses a Mullard DO20 output valve. This doesn't look like a re-hashed Marconiphone machine to me, so who designed the radio section of it?
