Roumelio. Posted August 3, 2017 Posted August 3, 2017 It's an interesting little amp, it has no real character of its own which is what intrigues me about it. I've had a couple of different things hooked up to it including a set of Yamaha NS10s. I have a set of Rogers export monitors hooked up to it at that moment which gives a very nice sound for classical music and jazz. No hums no buzz, no nothing. It's kind of just flat. 1

The 12AX7 is probably one of the more familiar valves to guitar amplifier enthusiasts. Pretty much a whole lot of amplifiers used them in the 1960s and 1970s including some of the more familiar Fender black and silver face amplifiers of the time such a the twin reverb. Here's a simplified schematic. Edited August 4, 2017 by Roumelio.

Fantastic but not to everyone's taste. Definitely try before you buy. Krispy Audio carry them and are a sponsor of SNA, contact Cameron he will be able to help you. They don't show up second hand very often. 1

Sub Sonic Posted March 18, 2019 Posted March 18, 2019 (edited) Thought I’d revive this thread. Recently I’ve been playing with some Richard Allan CG10T and really enjoying them. I’ve spent some time over on a DIY audio site and a lot of people have good things to say about Fane wide range pro drivers. Two drivers in particular are the 12-250TC and 15-300TC, 12” and 15” diameter respectively. Sensitivity is around the 100dB/W/m mark, and top end extension goes to around 17kHz. A pair of the 12” version arrived in the mail today, I’m looking forward to mounting them in a baffle or cabinet. They show promise just operating in free air. The amplifier will be 8 watts per channel which should be more than enough Cheers, SS Edited March 18, 2019 by Sub Sonic 2
Ihearmusic Posted March 18, 2019 Posted March 18, 2019 I will be looking forward to your review. I am also on the hunt for a high efficient full range driver to pair with my 8 watt 300B SET. I am looking at the Audio Nirvana drivers. I currently employ the ZU Soul Mk II and they do sound greate.......But one never knows! 1
mwhouston Posted March 18, 2019 Author Posted March 18, 2019 (edited) I have these Beymas for sale. 12” concentrics 96d/ efficient. 8ohm.The tweeter section is 105db efficient. The tweeter is 2” titanium and Mylar. With or without boxes. The drivers will take 700W. http://retro-thermionic.blogspot.com/2014/07/voxconcentric-beyma-12-high-efficiency.html PM if interested.

I have some others, like Axis, Krix and Vaf's but the ZU's beats them all. I have some other valve amps but the 300B SET is the best fit for the ZU's. Shame you are not in Perth. You could have borrowed my 300B mono blocks for a bit. 1

Out of curiosity, in what areas do you find the Zu’s beat the other speakers?

I was also looking at Audio Nirvana, amongst others, but their prices seem to increase in a linear fashion with cone area, and then shipping is also very expensive from the US. I also found varying opinions on the sound. The Fanes are more reasonably priced, and comments about their sound seem to be more consistent so I thought it worth a shot. I was very tempted to go for the 15”, but the enclosure size would have needed to be considerably larger for a similar low end response. I do have DSP and measurement gear but I would like to do this the simple “pure” way - 8wpc class A, direct to the driver, then add subwoofers for the very low end. We will see. Cheers, SS 3

You will need to do something about the "baffle step" ..... unless you were to compensate for the baffle step by running the "subwoofer" up to high frequencies (eg. few hundred Hz+) and locating the subwoofer(s) right next to the mains.
