Hello Arn, when you mention you're trying to find "these old tube amplifiers", you meant Dynaco varieties? I am sure there is a plethora of sources for original ST-35, ST-70, MKIIs, MKIIIs, and MKIVs. These sources range anywhere from local flee markets, thrift stores, antique stores, estate sales, and garage sales to electronic flee markets such as CL, eBay, Audiogon, discussion forums, etc. You're sure to find some on eBay and Audiogon. The average going price for ST-70 on eBay is about $300 + shipping.
You can also build these brand new. Parts are available from Triode Electronics and Dynakitparts. There will be a plenty of helping hands here if you are this route, even though you probably won't need it.
If you meant "these old amps" as any kind of tube amps, they are infested everywhere. eBay is usually a good place to start for me.

Craigslist is pretty good in the bay area. Well, it originated from SF, right? I'd look there first.
