Luxman R-1070 receiver repair and spares
I would like to obtain some spare parts for a Luxman R-1070 receiver.
Are Luxman still trading? There is a web site but it is all in Japanese. The parts that I want a a) Power on switch, b) Volume control (strange four gang effort) c) Input selector. d) Light bulbs e) The relay that connects the speakers once the unit has powered up. (Items b and c have become very scratchy - is it possible to resuscitate them?) -- Michael Chare |

I evenually gor around to buying some De-Oxit and using it. I have to say that it is surprisingly good, and has removed all the crackle from the input selector switch and the volume control. My Luxman receiver is now working like new, which is good news as I don't believe that I could have bought replacement parts. Had I known about this stuff I would have bought some years ago! Thanks for the advice. I am always amazed at what I can learn from the Internet. -- Michael Chare |

... I plan to try their Pro Gold soon. I was sent some instructions. For Potentiometers they say: Spray a short burst (0.25 to 0.5 seconds) of DeoxIT D5 Spray with extension tube into contact area. Operate control several times to break up oxides etc. Apply DeoxIT D5, CaiKleen 41, CailKlean A/V or other cleaning spray (that does not leave a residue) into contact area for 1-2 seconds to flush DeoxIT, oxides and other contaminates from contact area. Apply ProGold (G56,G5MS,G100S), DeoxIT (D5S D5MS, D100S) or PreservIT P5 spray to complete treatment. (For components prone to server oxidation, repeat process a few times before applying the final step.) For Relay contacts, battery terminals contact bars, edge conectors, commutators (all accessible contacts): Using the ProGold or DeoxIR Spray, WIPES, PEN, Precision Dispenser (liquid), apply directly onto contact surface. After a few seconds remove contamination and excess ProGold or DeoxIR with a lint-free cloth (#LFC-C). Repeat until linf-free cloth appears to be free of contamination. To complete the treatment, apply ProGold, DeoxIT or PreservIT. Wipe off all excess. To quote "As a general rule, use ProGold for best performance on plated surfaces and DeoxIT as a general prupose treatment." HTH -- Michael Chare |
