tyu, I've never tried pushing it to the limits to measure the maximum output power it's capable of. In the original VTV article Alan Kimmel says the 8 tube version will give 210W rms into 8 ohms. There, he makes no mention of the output power with fewer output tubes. However, in another copy of the article I found on the internet, the specifications for a 6 tube and a 4 tube version are appended at the end. The claim there is 115W into 8 ohms for the 4 tube version. That sound somewhat high to me; roughly speaking, the maximum power should be limited by the current the output tubes can handle, and so with a halving of the number of tubes I'd have expected roughly one quarter of the power handling, not one half. My guess would be about 50W therefore, but as I say I've not felt inclined to push to the limits to measure it. I've measured up to about 25W rms into 8 ohms and stopped the experiment there.
