Greetings all,
I have recently purchased what looks like an unused crystal oscillator from the ubiquitous ebay. marconi crystal oscillator identity : FQ-3121-11 Freq : 4960khz Serial no : H14730 Temp range: -10 to +55 Operating voltage 20vdc cylindrical approx 10cm x 5cm 0.75cm coarse(?) screw flush with top weight approx 500g spring mounted fine(?) adjustment screw central top - allowing adjustment once pushed down hermetically sealed case valve type connector on base with 8 connectors - wires are threaded through 10mm x 2mm tubes colour coding yellow/yellow/blue/green/yellow/yellow/red/white Apologies for the long description Does anyone know what the connections might be? Seems a shame to dremel open the case yet... I have attached a pic if that helps Cheers Steve Roberts
