How powerful is a Wavac MD-300B

It often comes down to the transformers and the overall caliber of the circuit. There are some SET amps that are very powerful and others not so much. I don't know about the Wavac, I would have thought that they would be in the high power bracket yet others say no, so...

When I had them hooked up the Sophia Electric 300B mono blocks easily drove my Tannoy Kennsingtons to very high levels in a large 16' X 30' room with 10 foot ceilings. Using the deHavilland UltraVerve as pre.

I just found a review by Jack Roberts at Dagogo of the EC-300B, where he begins by stating that he also had previously lived with the MD-300B for quite some time prior. I found it strange that he did not give a comparison between the two.
I then found his previous review of the MD-300B. He basically says about the same for the both.
At three times of a price difference... there should be a big difference...

I have no experience with Wavac, but...

In a moderately sized room I had some years back, a pair of Cary 300B monos cleanly drove my (89db IIRC) Merlin VSM speakers as loud as I ever wanted to play them.

Just one more data point for you.

One other issue with Tannoy speakers and their sucess rate (or failure) with 300b SETs is that some models are easier driven and a more efficient load than others.It`s probably a mistake to assume all the Tannoys will have a similar result with the same amplifier.
