Wavac EC-300B - Feedback Request


Are there any Wavac EC-300B owners out there who can share some feedback with me?

Wondering about things like Wavac reliability etc.

Any tips on tube rolling etc.

Would you recommend it to a friend?

I run an EC300B on Duevel Bella Lunas with Murata ES 103 super tweeters. Prior to this I was using a Graaf GM20. The quietness and control, soundstage and colour density of the Wavac are without comparison. I have changed to EAT300Bs from the stock TJs and use t
Tungsol KT66s which really are 6l6GCs as driver tubes. Much tighter sound than the cryo-ed JAN Philips 7581s or the coke bottle Shuguang 6L6s.
I have heard a Wavac 300B in my system and it really, really struggled. It could barely drive my speakers to an acceptable level, and it was clipping at low listening levels. If you buy one, make sure you pair it with efficient speakers.

I have heard the 805 based Wavac SET on my system, and it left a much more favourable impression. It was more linear and had a gorgeous midrange - cool and elegant. It still could not drive my speakers to an acceptable level and was still rather bass shy.

If I'm not mistaken your speakers are 91dB and fall to 3 ohms at one point. Furthermore, the manufacturer recommends 40WPC.

I doubt any 8WPC 300B would perform better than the Wavac.

YMMV
Tube amps should be seen as ONE unit with a matching Speaker (high efficiency, simple X-over...). The magic is in the first few watts.
When it is done right, you hear in the first 3 seconds why 2A3, 45, WE300B and others have such a huge reputation.
I listened in the 90's to such a Wavac 300B - with NOS WE300B -, an Original from Nobu Shishido, in combination with a 99dB Horn Speaker (+slot horn tweeter, fast, fast, fast, a Korean Design) with Basis Debut vac. Graham 2.2 and a Takeda Miyabi Cartridges. It was one of the super rare demos where the Visitors didn't leave the room. They waited the 40 min. for the next 20min run. That was the moment for me, where I got the impression what's all about.
That was the real High End. A perfect combination, a very impressing Demo.
