Today, they still find use as a valuable tool in testing germanium small signal and power transistors.  This is the Mark II version which, as a bonus, relies on a mains PSU rather than the clunky U10 battery derived power supply of the earlier version.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOne interesting tie up is with the AVO CT160 VCM suitcase valve tester, as both instruments share the same meter. So….. if you have a CT160 with a dodgy meter, this transistor tester should supply a replacement.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eA little bit of dismantling, swop the scale plates and, voilà, hundreds of pounds of valve and restored function to a poorly CT160. Meter replacements for the CT160, either using a substitute meter or an AVO replacement, command a high monetary value. However, today, you can obtain a replacement meter surrounded by a transistor tester for a very keen price.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eManuals for the AVO Transistor Analyser Mk2 can be readily found to download on the internet.\u003c\/p\u003e\n\u003cp\u003eThe metal label at the rear of the instrument reads as follows:-\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eMade in England by AVO limited, Avocet House, London\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003ePlease click on the following link for more \u003ca href=\"https:\/\/mullardantiques.co.uk\/collections\/radio-test-equipment-vintage-and-modern\" rel=\"noopener\" target=\"_blank\"\u003eradio testing equipment\u003c\/a\u003e\u003c\/p\u003e","brand":"AVO (ACWEECO)","offers":[{"title":"Default Title","offer_id":56860995223927,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0303\/5122\/8972\/files\/AVO_Transistor_Analyser_MkII_CT446_Portable_Test_Meter.jpg?v=1773317622","url":"https:\/\/mullardantiques.co.uk\/en-eu\/products\/avo-transistor-analyser-mkii-ct446-portable-test-meter","provider":"Mullard Antiques and Collectibles","version":"1.0","type":"link"}
