I am thinking, however, of using a backwards 120v/12v transformer in parallel with the 240 VAC primary of the plate supply to feed the antenna relay coil - that way it would switch when I press the front panel play lever as well. Might not be as good, my present set-up gives a slight sequential timingadvantage: antenna first, then plates on. ==============================
Regarding the antenna connection/HV timing issue. To be 100% sure that there would be no catastrophic incidents if the HV was applied before the antenna connection, I use a Johnson 250-39 TR switch. That way the antenna is always connected to the TX.
