Hi, guys. Couldn't help, but, reply to this question. First,let me tell you that there is a reliable guy in Florida who re-builds crystal cartridges, including the high voltage crystal recording cutter used in manny machines. He's not cheap, but, he is good. Periodically, he lists items on ebay, usually under Other phonographs, an off-shoot of collectables, radio, television, phonographs,telephones. That photo is of a Recordeo. I have one that doesn't have the radio. They were not great units. The special audio transformer used in Recordios tended to short out. Others didn't always use the same circuit, and may be more reliable. Recordio got themselves a rather bad reputation. Well deserved, from what I learn. Discs: Hard to find. Needles: Came in several qualities, from cheapest, good for only one recording session, to the best, saphire,good for several reccording sessions. If you are squemish about this, I'd say just skip re-building cutter. Of course, a fully working machine is worth more. Recording is tricky. Volume is important, as is weight of cutter, dependent on type of disc used on recording, and type of cutting needle. The recordette burned the recordings. That tended to dammage the crystal. Recordio didn't care. Does this help????? If I may make my own quote of another forum member, here goes.. "I may be growing older, but, I refuse to grow up!"
