You have taken me back 55 years when I was in Tech School.

We did some really cool projects using tubes.

Thanks.

Awesome project! Even though I hung around a lot of huge tubes in FM transmitters, I never felt comfortable with them (technology or voltages). I had my fair share of scary moments while working on power invertor systems (including a flaming 5-pound capacitor whistling past my ear when a unit I was working on failed under full load). So, for me, I like to my voltages low and my projects safe.

Hats off to you and enjoy your new sound system!

Awesome project [mention:f94915692f8b4654ba9080db400d0af5:e9ed411860ed4f2ba0265705b8793d05] . It looks great in the box.

It has been a while since I attended a HAM fest but I have been to the flea market in Carp. [emoticon:fbd079a1c4f748c5a234faee215de9cc]

I can't quite make out if you have an isolating transformer for the HV power rail yet.

If not then you really should.

Powering directly from the mains is incredibly dangerous and I should hate for E14 to lose you as a contributor.

(Much more so in 230V regions, but still not safe and contrary to regulations in 110V regions.)
