The Pearl Acoustics 170, single ended, vacuum tube power amplifier - the story so far!

After over a decade of trying, our first own design amplifier is built, but there's a problem! In this video I outline the story of its development and talk about the approach we took but also the dilemma we now find ourselves in! We include some sound clips of it playing and discuss our next steps! Enjoy.

Topics covered:
00:00 - Introduction
00:25 - Why our own amplifier?
02:07 - The design approach
05:53 - How I think it sounds (of course I am very biased)!
07:53 - Our big problem!
11:12 - Actual sound examples played through our amplifier and loudspeakers
