for my latest DIY SV572-30 SE
It uses low current thru small 1940s vintage Berco output transformer.
Happy Ears!

Thanks to Tim, Alex and Alan coming to my place to have listened to my
new diy speakers and we have a wonderful evening. I hope they enjoyed
it too.
While I'm still make the most out of the "Tannoy-Silver", I later add a
Jensen vintage 16 ohm alnico horn with a 6db high-pass to suplement
13kHz above. The result is very positive, the violin and piano becomes
more live.
For the Jensen, I tried several cap types, metal film, milar, and paper-
in-oil. You know what I finally stay with.
Hv fun!

Eric, thanks for receiving us. Besides the speakers, the tea was great
too !
Let me guess, paper in oil, yes ?
This horn is really amazingly build ! All of us were impressed by the
craftmanship. Talking about a home made horn like this, guys when you
visit Eric, go to see his "factory".
Lets talk about the sound. I would say it is a very different and
unusual speakers. The best parts I found, IMHO, were piano pieces and
male vocal. They were just so real. We also listened to the "3 noter"
Choi Kam, the vocal seemed to be a little bit forggy and the very high
seemed to be missing. I assume the cross over net work may not have
tuned to the right point. I think also the 6A3 may not have enough power
(just 2W) to control the woofer to its optimum. So Eric's later plan of
electronic x-over and bi-amp is expected to make this speaker sing.But
over all it is a very very good sounding speakers Eric has built,
congratulation !!
Eric is tweaking it everyday, lets watch this "new born baby" grows to
its best.
I think adding the Jensen horn would be a very good idea.hear some folks

I am glad that the forum finally recovers. As for the impression of
your new speaker, I am in agreement with Alex's assessment but just
with the following points to add:
1. I do not think the crossover is properly tune up yet, there are
booms at particular frequency range in the treble and recession in
upper mid-range, which is more noticeable with female vocal. It may be
rectified with electronic crossover you are planning to use.
2. The sound has the longest "tail" or residue (don't know the right
word in English) I have ever heard which sounds absolutely increible
for chorus and piano but unnatural for some recording.
3. There is certainly more bass in terms of quantity and range compare
to any Tannoy speaker I heard as none of them are with back loaded
horn.
4. It may require more power as the higher power TT21 SE amp obviously
has better control.
5. I think single strand solid core speaker wire may give better result.
To conclude, I think the speaker sound great and the result of amazing
dedication. I still cannot believe it is a DIY speaker particularly one
made under the living environment in HK!
Keep us posted with your post-construction tuning work and I expect
even further improvement from our Master of DIY Audio!

I totally agree with the opinion giving by Tim, Alex, and other ideas
from those friends who had spent times to listen to this fun speakers.
These valuable comments from all experienced listeners are TRUE to
describe the performance for the speakers, so that I can have
guidelines for what to improve.
Yes, the horns sound very colouration, and is very sensitive if you
change listening position or change anything else on set up, like
speaker wires, degree of toe-in, amps & tubes of course. The
colourations reflect some strange sound in some particular ranges and
giving out beautiful pieces at the same time.
What I need to do hereafter are to remove the odds and without taking
away its beautiful pieces. There are much to dig out.
BTW, last night I hooked up the EL34 UL/PP (just the fire-up tubes,
later I will install the real mccoy GEC KT66 and EL37 to try) to drive
them. It's copmpletely another story, bass are tighten and more 'rock'
with solid punch. The 12" Silver in horn load is really sensitive.
Again, the Jensen tweeter horn can be removed in cap coupling.
