New product - VTA driver board cover (photo)

Does anyone happen to have a picture of this installed?  I believe everything that is necessary to be installed on the bottom of the PCB has already been done unless I'm missing something.

Accordingly, there will be no exposed hot parts, either thermally or electrically.

So while I would recommend mounting those four components on the bottom, you could probably just bend them slightly and you would have enough clearance to leave them on top.
As for the PIOs, I always recommend using insulation, either electrical tape or shrink tubing around the entire body,
the capacitors won't get warm at all.

What Peter said - it doesn't take an EE degree to understand the dangerous level of electrical exposure on that board - the cover is cheap peace of mind in my opinion and retains the overall aesthetics of the amp to boot.

I am not sure if you were responding to my remarks and suggestion about ceramic screwdrivers..but I said nothing about the idea of covers for any tube amplifier being a bad idea. The ceramic screwdriver is merely additional protection.

I was responding to your remarks - sorry if they came off a bit snarky.  I think Peter and I took it as an alternate suggestion to mitigate the problem of the exposed board, which is the point of the cover.  I have a set of insulated screwdrivers I use when adjusting the bias, not sure I've seen the ceramic ones but I'll certainly look them up!
