The mounting screws should be used with care. If they are screwed-in too far with no intervening front panel they may foul the internal parts. The screws are cross head types but they are easily used with a small 2mm flat-head screwdriver. The two capacitor gangs are designed for standard MW radio use, those being a 4 to 60pF oscillator section and a 4 to 140pF antenna section.\u003c\/p\u003e\n\u003cp\u003eTwo 12pF trimmers are present on the rear for super-heterodyne alignment. For simpler projects the two sections connected to the outer two wires would be connected together to form a 200pF variable capacitor, and the trimmers set with the vanes un-meshed for minimum additional capacitance. The connections are shown in a sketch in the additional pictures. The case body measures 20 x 20 x 12mm and the shaft extends 4mm from this.\u003c\/p\u003e","brand":"HJW Electronics","offers":[{"title":"Default Title","offer_id":58501262639488,"sku":"AM VC THUMB RED","price":5.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/vc_red_open_top_w.jpg?v=1788199154","url":"https:\/\/shop.usefulcomponents.com\/products\/variable-capacitor-dual-gang-60-140pf-200pf-total-large-red-thumbwheel-knob-screws","provider":"HJW Electronics","version":"1.0","type":"link"}
