Default Re: Mr Carlson does an AR88/CR88

Episode 3 is out.

He's replaced the main reservoirs and the bathtubs, found some livelier 6SG7s and run into a crackly audio problem.... Along with flickers of the VR150/30 regulator.

It's our pal, THAT capacitor.

So Paul doesn't seem familiar with the 'that' capacitors in valved audio stages in general. Nor does he seem aware that 'Micamold' capacitors are 100% mica-free and just crappy paper jobs hyped up by marketing.

I notice that he's wary of the oils in some capacitors without saying why.

It's interesting watching him discover stuff we're well aware of, but as he replaced the bathtubs on sight, as well as the big block smoother, he has been using prior knowledge of certain components. So I think he genuinely isn't familiar with all the usual players and we're getting to see him diagnose them from scratch.

Good footage of 6K6 grid glowing and darkening, shot through convenient hole in the top mica.
