It's a year old debate. I don't see any advantage whatsoever adding resistance over what NGK recommends.
For a change I actually agree with you DR

Did you instruct on the hazards of mercury when the mercury arc rectifiers got broken or scrapped?
Heard stories of the floors of control rooms having tiny globules of mercury sloshing about. 8

I understand that you are only doing 'O' rings for 500/550 but someone needs to come up with a suitable replacement for 12115-300-305
(See Service Bulletin no. 42) attached. These allow the later head gasket intended for later cylinder heads with the knock pins to be used on early heads. As I understand it, a nitrile 12.5mm ID x 2.0 O ring is a decent alternative. A quad ring 'x' section, might be even better but might take a bit of sourcing. [ Guests cannot view attachments ] 12

My advice ... get yourself some Duplicolor DE1615 with ceramic .. that's what all of the guys and me on the US site use. Very close to original Honda shade. Hard to get hold of but worth the effort IMHO

US cleaners are switching several hundreds of volts at very high frequency into a highly
capacitive load and are notorious for going pop...even the Ultrawave pro units do it. The usual failure items are power transistors or MOSfets that drive the US transducers. They are the 3 legged devices on heatsinks. Best bet is to use a multimeter on diode test function to check every diode and betweel all legs of 3 legged output devices on heatsinks. The usual failure mode is short circuit, which will show 0v on the diode test. If you experience this then best to desolder the device and re-check out of circuit just in case another component such as a coil etc is affecting the reading. 14
