Well, I cannot argue with what these websites say. When you dig into the datasheets, you often find the term "pre biased" and such. The marketing department can call them what they wish--to that I concede. However, it is not a term of art. The term is not in my copy of the IEEE dictionary (c) 1996. Neither is it in my copy of The Art of Electronics. -
I too got lucky with a JKA Feintaster for a bit under £200, they seem to go for around £400 which I find silly as a brand new one from cousinsuk is less money. Tom

It looks similar to some AS movements, but it's not identical to any I can find. There may be a logo / number under the balance wheel?? -

Many would disagree: https://www.rohm.com/products/faq-search/faqId/234 https://uk.farnell.com/c/semiconductors-discretes/transistors/bipolar-transistors/pre-biased-digital-bipolar-transistors https://uk.rs-online.com/web/p/bipolar-transistors/8232832P?gb=s https://uk.rs-online.com/web/p/bipolar-transistors/0580240?gb=s (RS don't have a specific category, but over 1000 "digital transistor" items). -

Thanks, ManSkirtBrew. I started looking for a setup like yours and ran across this. It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon. I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.
