I must say I am surprised that the Paypal comment got more response than
my amp related question on relays. I got two off list replies and none
on list

Good day gentlemen, I am putting together a small amp with an old tube
from my junk box trying to learn as I go. I built a large power supply
last year for a 4-1000 but I am a little cautious of 5000v my first time
around so I will start small with a 40M monobander with a triode at
lower voltage.
I am working on the power supply now and just bought a relay for the
soft start. The input will be 240v both side switched with two SS
relays. When I install the soft start do I need to put a resistor on
both sides of the hot line or is one side sufficient?
The main question today is the soft start relay, 25A@240VAC P&B PR7DYI,
plenty good to the low power I will be running. The 24vdc coil is 287
ohms, it will be on the 120VAC line with a 1N5408 in line. What size
resistor and cap should I start playing with??
Rich, kd0zz
