[Boatanchors] Inrush Current Limiter

[AI2Q]

Hi Keith:

Have you thought about alternative inrush control methods?

For example, I use small DC relays for the purpose in my amplifiers. They're
fed through a diode rectifier from the AC line and use a series RC
time-constant to set the time until they kick in. A high power WW resistor
is placed in series with the transformer primary. It's ultimately shorted by
the relay, thus feeding normal AC line voltage to the xfmr. Works like a
champ.

Greetings,
Anyone know of a source (small quanity) for thermistor inrush current
limiters suitable for kilowatt + amps. I've found several manufacturers but
I can't dig up a suitable supplier.

Thanks,
Keith, ve3ts
