[QUOTE="fredeb, post: 798109, member: 13623"] I think I'd like it to read a little better than good/worned/fail - it would've been cool if there was somewhere to stick a multimeter in . Dit lyk maar dodgy vir my , daai ding Karel . :???: I have been wondering about this though : [url=http://www.ebay.com/itm/VACUUM-TUBE-TESTER-DIGITAL-LCD-TESTER-KIT-with-4-6-3V-power-/162048890376?hash=item25baddd608:g:vRUAAOSwJkJWkbmo]http://www.ebay.com/itm/VACUUM-TUBE-TESTER-DIGITAL-LCD-TESTER-KIT-with-4-6-3V-power-/162048890376?hash=item25baddd608:g:vRUAAOSwJkJWkbmo[/url] [IMG]http://i.ebayimg.com/images/g/vRUAAOSwJkJWkbmo/s-l1600.jpg[/IMG] [IMG]http://i.ebayimg.com/images/g/0Q8AAOSwX~dWkbmj/s-l1600.jpg[/IMG] [IMG]http://i.ebayimg.com/images/g/cAkAAOSwZG9Wkbmc/s-l1600.jpg[/IMG] The thing that worries me about this one though , is lack of instruction . The ad doesn't mention [b]what[/b] gets measured . It does say , " Transconductance ( Gm ), Internal resistance ( Rp ) and Gain ( ? ) can easily be calculated using 2 simple measurements . Rectifiers and diodes can also be tested . " Thoughts on this device ? Might be a bit tedious testing 16 double triodes , so as to match them . [/QUOTE]
