No, it's not a tube rig, it's the latest Icom IC-7700.

Thanks for that Lamont.
The device is a transceiver and the power usage on:
Transmit is 850VA and on
Receive is 210VA

Wow John those figures are high -- is it a tube type radio?

210VA = 95.55W
850VA = 386.75W

Does sound like a tube rig.

Tell me you are not buying this transceiver for SWL.

In any event you better be real careful with an inverter powering this
transceiver as it looks to have an auto switching power supply in it.
You would be safe with a 115V inverter but you might see trouble ahead
with a 220V inverter. I've seen inverters hiccup when a load is switched
on, which might cause the auto switching supply to go into the doubling
mode for 115V. When the inverter recovers to 220V you will be lucky if
all that happens is you blow a fuse. Whether or not you have a problem
might depend on timing. Where the inverter is in the AC cycle when you
happen to switch on the radio may determine if a failure event occurs.
Having some load on the inverter like a lamp before you switch on the
radio may help stabilize the situation. Good luck.
