This guy thinks so.....

Well crafted homebrew amp - 10-160M - floor amp. 110V. This amp is very well made - good parts. Running 3 4-400 tubes in it!! Lot's of power!! I have NOT tested it - came from a working estate. $350 - trades considered. Lot's of pics available. Pickup only in Lexington, KY KK4WS at arrl.net

Probably Eimac tubes or the equivalent. Goood and decent transmitting tubes, just under the 3-500's I believe.
