In "theory" your correct Ron! I have seen more modern homes in my area wired "backwards" as far as modern AC phasing these days. With 2 legs 120 v "split" at the meter box, using a neutral ground, most of todays homes arent "phased correctly" in the 1st place throughout new home elect construction. In the old days, you didnt have a "choice" (2-wire incoming 110 v ac) that powered vintage homes from the AC pole trans back in the old days. And didnt care of which way to plug-in your vintage radio unless you unpluged and flipped the AC connector over, Same size spades on each side of AC connector supplied by the mfgrs in those days. Was phasing correct in those vintage days? As far as "proper match" on modern AC lines, we cant always assume all todays modern recepticals are "correct" with modern day phasing sometimes either. Best test is using a AC voltmeter to "ground", then select your connections to chassis & switch, because every 110 v socket varies "coast to coast" in the USA for proper "polarity" these days indeed when supplying AC power to vintage radios!! The modern day electricians wiring homes really dont pay mutch attention to (+/-) when it comes to "phasing AC", so therefore, check your local connections, or your vintage "schematic wiring" could be opposite your desired results for incoming AC to your vintage radio chassis indeed! Just my thoughts, Randal
