Woo Audio Amp Owner Unite
Mar 27, 2020 at 3:02 AM Post #40,831 of 42,299
I found a good deal on a pair of Devore Fidelity Super 8s, which were the hot speaker about ten years ago. I owned a pair back then, and while I enjoyed them on a VAC Avatar SE, I had zero luck powering them with a Wavac 845. I ended up trading them for a pair of Merlin TSMs which were wonderful, especially with a pair of AirTight ATM3 mono amps. Then about five years ago, I sold off most of the gear and moved to a headphone only setup.

I used a pair of ProAc Super Tablettes with the WA5 and it worked surprisingly well. Now the Devores are back in the house but I’m a few months away from being able to set the room up, owing to a house remodel.

Does anyone use their WA5 with Devore speakers? The Super 8s should be tube friendly, but I recall they preferred the Avatar’s 35 wpc to the Wavac measly 15 watts. My experience with the ProAcs leaves me optimistic that the Devores and the WA5 will be a better match.

@davehg The sensitivity is rated at 90dB/W/m and impedance @8 Ohms so it should not be a problem. Of course the size of your room and how loud you like to listen at plays a role in drivability.

Hi everyone, I found this pair of tubes for sale. At first I was looking for some tungsol 6fg8's and they seemed quite expensive, and then for a much cheaper price I found this. It is not 6F8G but 6B4G. I tried to find some information online about 6B4G but could not find any. They look almost the same as black glass TS 6FG8.

I'd like to know if they sound the same as the TS 6FG8 or if there are any differences at all that I should know about. Also if anyone has had the chance to try both the tungsol 6fg8 (or any 6fg8 tubes) and the mullard ecc35's it'd be great for me to know the main differences between both pair of tubes, and which pair you liked the most. Many thanks!

Question about the WA3; if it looks identical to the WA6 but is OTL, then what is inside the enclosure behind the tubes???

WA6 is better for modern headphones.

Not at the output. Some tube amps have an output transformer (WA6) and some don't (WA3).

So, I believe in that enclosure we have the power transformer (WA3) or the power transformer+output transformer (WA6)...
