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?

Hi Rchan, I have a WAVAC EC 300B amplifier and it is a excellent sounding amplifier when matched with efficient speakers.
I have used it with the Avantgarde Duo Omega, Ocellia Calliope & Tannoy Westminster Royal speakers with wonderful results.
The Western Electric and KR 300 B are highly recommended.
Thanks Jason.
I have the Wavac, currently driving the Phy-HP KM30 coaxial driver in an open baffle. The virtues of the amp: Extremely quiet, supremely reliable, virtually no warmup time, all the virtues of 300b midrange with excellent extension at the frequency extremes. My only wish is that it had separate taps for 4, 8, 16 ohm output. The outputs are available internally, but require some soldering skills and courage.
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.
