AVA mod Dynaco Pat-4 WOW - Click HERE for Original Thread
EV-MAN
Built a Dyna Pat-4 kit back in the Mid 70's used it for 10 to 15yrs. Put it with the rest of the junk sorta forgot about it. It was just a OK little preamp. Went to a friends house that has a system that he put together. Walked out his house with the fever. So here I am again. Went to surfing the web looking at the new stuff & Vintage. Ran across Van- Alstine got to reading on his web site found out that he had done some mods back in the 80's for the Pat-4. Replaced the caps on the boards. Built the new power supply which is much more powerful & did the other things he recomended. And now the good part. This little preamp that was OK is now FANTASTIC. you would have to pay several hundred dollars to get one as sweet as this. Forgot how much fun it could be especially when things work....Well its off to the next project. HAPPY SOLDERING
