Not sure if the last picture I posted is visible to all, iCloud seems to move the URL's around. Trying again from my email service provider's web-hosting service...

It was there yesterday, then it wasn’t.

Thanks - if it hadn't been for the move down south, this would have been done by now. What also hasn't helped is the fact we've had to go from a 3-bed to a 2-bed apartment (albeit with bigger rooms), and give up the self-storage (the ones here are double the cost of what I was paying in Chesterfield).

So it's taken a Herculean effort of sorting out and throwing away or donating junk, just to get to the point where I was able to carve out enough space to work on these things.

The right channel amp is almost at the point where I can do a heater test. I just need to solder the 12V trigger wiring to the 4 pin XLR inlet - before I do that, I want to sanity check with the pre-amp to ensure the 12V is appearing where I expect it to!

I have already tested the soft-start so that should work, but need to make sure the DC blocker doesn't go bang....

Oh I don't know, I think your recent efforts have more than held up the good name of the House of Shod, Mr C!

A successful heater test - actually, this also tested out the remote switch-on (via pre-amp), soft-start and DC blocker. The DC blocking caps didn't explode, so that's a good thing. This also told me that the on-light is WAY too bright - need to get a much dimmer one.

I thought (ha!) that I might get it finished today - nope, not even close. Maybe next week....
