So this is 3 hours, but well worth it. I know people who've put it on at 1.5x or 2x, but there's a point where a company shows a spreadsheet of their actual numbers and how the tariffs affect their product. Spoiler alert: on a product with a 5$ margin that's MSRP is 130$, it's costing them over 90$ for each one that's sold.

Is electrolytic capacitors reforming needed? What is common attitude to this procedure? I've got quite a few pcbs that I completed 8-10 years ago. Most projects are from amb and KG. I soldered PCBs, washed them and put aside on the shelf. But life is life, time has passed and finally I thought that this year it's a good time to complete them. Pcbs were never switched on. Caps I used are all good if not the best brands: Panasonic, rubycon, nichicon. Never frozen, never heated. However I'm confused how short the shelf life is according to manufacturers specs: 2 years, maybe 3. I remember receiving caps from mouser that are almost 2 years old, I'm curious what they do after 2 years, dispose them? Anyway, do I need to do anything about caps? Do they really degrade, or is it just a BS from manufacturers to stay on safe side? Maybe 8-10 years are nothing to worry about? I really would avoid desoldering and replacing everything if possible.  

No change needed. With LT1021-10volt the current is 10V/787ohm + 1 mA from ground pin = 13.7mA. One builder increased current to 18mA by changing resistor to 590R. Now I use 590 as well in my mini T2 DHT with Emission Labs tubes and I’m happy.

I mean we all thought that but wanted to wait till you were ready.
