A suppressor is normally about 20K ohms and will make very little difference to the HT voltage, in fact it will reduce it slightly. When I was serving my apprenticeship at the BTH in Ford Street in Coventry in the early fifties they did tests with suppressors on the magneto’s and actually found that it improved the spark, it cut out spiking and gave a cleaner spark. In those days you could be prosecuted for causing interference to the television signal. I run my Scott on Champion L86 and have no problems, they last for ever, if you do need to replace them you can buy them from the Green sparkplug gentleman for about £1.50.
