Hi,
Some ten or fifteen years ago I used a circuit from the ARRL Handbook to
produce a sequencer (the original was perhaps used for remote pre-amp
switching). The sequence was:
1 Amp output relay (Kilovac HC1)
2 Amp input relay (Kilovac HC1)
3 Amp bias
4 Key transmitter
Keying was controlled from the amplifier though I gather no everyone finds
this acceptable. The delays could be varied slightly and release was the
reverse sequence.
