Dynaco PAS-3 tube preamp
NEW NOTICE - this page is soon to be totally updated around February 11th, so check back soon for major updates!!
NEW NOTICE - after 20 years of working on these preamps and all the customer feedback and questions,
I've decided it's time to write a COMPLETE MANUAL on all the recommended improvements and modifications
that can and should be made, as well as decent and readable schematics, complete with photos and detailed descriptions
of how to make the most of this low priced best selling preamp.
The finished product will take me a month or two to complete, and the finished price will be $16 printed and mailed or $12 as a PDF download.
In order to judge interest and also get my hands and mind in gear to get it done, I'm now accepting PRE-orders which is a $5 down-payment
the balance will be billed when it's finished, and will include a full price credit towards any order over $50.
