Over the years, I have gotten a lot of great info from this site, but have never really helped out here. Hopefully this will help a few people out.
While this place has a ebay store, Its pretty much impossible for them to list their entire stock (Take the virtual view of their store and you will understand why).
The store http://www.apexelectronic.com/index.htm
Located in Sun Valley, California
8909 San Fernando Road, Sun Valley, CA (Enter that in Google Maps)
I have gotten AWESOME deals there over the last few years.
If you decide to actually go there, plan on spending at least 4 hours just looking.
I would guess that over 90% of their stock is NOS. Tubes, transistors, resistors, etc.
Although I have reduced their transistor stock quite a bit.
Edit:
And before you ask, no, I do not work there. I just think its a great place for parts.
