Re: recessed bias adjusters. I put a length of heat shrink on the bias screwdriver supplied with my R8 then shrank it to the shaft but not the blade area. I then trimmed the heat shrink so it was sticking out a few mm past the tip of the blade. Now the screwdriver easily slips onto the bias adjuster and a slight twist sees it slot into the top.
Honestly, if you use the amp and "exercise" these rotary switches regularly i.e. check the bias weekly, the factory ones will likely never have this problem.
Living vicariously through your videos. Not nearly enough time to work on stuff like this as often as I would like. Thank you...great stuff!
So great to watch this! Like watching a surgeon work.
This is great content, thanks Skunkie I've just received my X7 today so watching this series closely. Subbed!

Did I see solid state diode rectifiers across the rectifier tube? Surely that makes the rectiier tube redundant???
It looks like they are wired in reverse of the tube, will have to look at that more closely.
@@SkunkieDesignsElectronics be very interesting to see what they have done there. Cheers Ian
Cracking vid. I've got one coming soon (ordered last Tuesday) to the UK. Shame you are in the US if I have issues (I hope not!)

Thanks for the advice 👍
Edit: can you move them when the unit is powered down?
Sure, they are simply mechanical switches and like most switches of this type, should "self clean" with use.
Do you know the purpose of that blue trim pot hanging off the switch?
Yes, that's to adjust the front meter to = the mv reading across the 10 ohm cathode resistor.
