Wow. Dynaco Pat-4. Now that brings back memories! Built one of those back in the 70's.
The Pat-4 took many into the transistor camp. But over time, many found that this early venture into the solid state world was not so hot--the Pat-4 just was not that musical. The Pat-5 was an improvement, but still early SS.
Have not heard the Bellari unit you noted. I do have a Bellari vp-129. What a nice sounding unit.
Get the Bellari. No brainer.
