THANKS! FOR YOUR REPLIES

I know they are basic questions but I appreciate the time taken to reply

ok back to the HRM

I am curremtly building my Hrm and was using Mcintu,s BM thread as my guide as its my first build .Q1- is it important that all capacitors are wired for correct polarity as only some are marked. Q2 using Mcintu.s pics I wired up the heaters using black white , but now suspect I should have used red black. which appear to be larger gauge . since both are 50w suspect this is no biggie. but put my mind at rest     
                                                        cheers Derek
