Default AVO TT169 Transistor Tester

Folks, just a post for info. I've read all the "Search" posts. Seemingly a half-decent in-circuit tester. This one however is un-used, completely un-blemished, & the blue plastic wallet is immaculate, and still works. Only cost a quid at an ARS junk sale! A diddy wee addition to my collection of five other types of testers/analysers(CT446 Mk2 to an Atlas DCA55).

Regards, David

Thanks for the replies, Kevin & Dave. Yep, a quid for an un-used NOS little tranny tester is a great bargain. My VMARS chum GM8AGM, Martin, got it for me a last week's Aberdeen ARS monthly junk sale. About three years ago, from the same place, he got me a Hartley CT436 Scope, fully working, for a fiver!
Another Tr Tester in my collection is a Kamoden HM-350, (there is a post about it ), which I snaffled myself at the same sale about 2 years ago, for just a few pound coins, but that needed some TLC.
Folk might query why someone needs 5 tr. testers, magpie compulsion maybe ? No - I attempt to use them all several times a year. Especially now that I've acquired an 21st century Atlas DCA 55. Its amazing to see old 50's/60's etc. testers hold their own against micro-electronics latest. And also see how my wee collection of "Crystal Triodes"(very first transistors) compare to more modern junction & FET's etc. Also, back in the 60's, I used to service & repair RAF CT446's. (And CT436's).

Regards, David

You did get a bargain. I think I paid a tenner for mine about 20 years ago. It is a pretty good in-circuit tester (rather better than most). I hope you got the 2 leads (one for small signal transistors with a strange double spike probe on the end, the other for power transistors with a pair of croc-clips) and the (green) probe to connect to the base of the transistor under test.

I've got one of these too, bought at a radio club junk sale for a couple of pounds, and in working order. Since acquiring it I've never needed to use it in anger!
