What model Dynaco preamp do I have?

On the rear of the unit it says the Model# is PAS.

A very good tube preamp in its day. Lots of modders upgrade them. It's successor, the SS PAT4, was nowhere near as good sonically.

That experience is what got me into tubes. I didn't know all those other PAS variants existed.
