It is exactly as I described to you. HV Board has 3 relays. One is for soft start, and the other two apply 240v AC to t; /archives//html/TenTec/2014-02/msg00030.html (9,637 bytes)

Yes I did understand. It shows the three factory supplied relays on the board ... The ones you say don't exist. ______________________; /archives//html/TenTec/2014-02/msg00032.html (9,159 bytes)

However, in my two amps, the HV is applied when the power switch is turned on. Maybe an earlier design t; /archives//html/TenTec/2014-02/msg00033.html (10,979 bytes)

Power is indeed applied to the transformer whenever AC Power switch is turned on a; /archives//html/TenTec/2014-02/msg00041.html (10,570 bytes)
