Lately cooking up a revolutionary "new" amp circuit, with all the advantages of single ended and also those of push-pull, without the disads. Not a new idea, but in the past "unavoidably compromised". Methinks I have solved the problem. Winding the transformers at present for a type 45s version. "Watch This Space"!
If is's as good as I think, the 4x6550 version will appear.
Here is a typical interstage transformer that that capacitor replaced. I still think one can get a better sound through a capacitor than a transformer, in spite of the current fashion for using them.
It seems one can get disks (sic) of what appears to be 90% bass drum. One can also buy "stereos" where they have carefully designed the large speakers to resonate big around 100hz. This means they don't need to supply a very big amp.
This causes the so-called "Jukebox" one note bass; although I think a bit of an insult to Jukeboxes.
So neigbours at the rear decided to open up the Summer with a front yard party. A tent attached to the front of the partially built-in carport to enhance the projection of the speakers, and proceed to boom at huge decibels (my widow glass was rattling.) for twelve hours starting in the middle of the afternoon yesterday (Saturday our time).
What can little ole me do about it with a lot of half-drunk maoris there? Arthur, the head of the house is actually a nice guy. But how nice really subjecting me and other neigbours to that lot? People on the other side of the road two sections away were aware of it.
There was no possibility of out-booming them, as Ecofan speakers are carefully designed not to boom.
But I can out-tweet them...
In the junk room was a little "TOA" brand outdoor PA horn speaker. Rated at 5WRMS (8Wmax) it said 100db @ 1 metre. So I mounted it just below my high up (on the outside) bathroom window where I could perfectly angle it to cover the outdoor party area. With the little 10W amp (2xEL84) I use in the workshop to check tuners, preamps etc and an oscillator I found that 1WRMS at 3000HZ made a really big noise.
When I tried it out about mid-day when they started up again I tried it at a not big volume and later a burst of one watt.
Arthur and wife were visiting in a flash, and I said to them the boom box was a bit much, and one thing followed the other, or words to that effect. I am always on the front foot in these sort of situations, and it has been a nice lower level most of the today, and better if they play something civilized like Reggae.
P.S. I'll have to invite soon Arthur to have a few "burbs" and hear a pair of proper speakers. And I have plenty of Reggae and dub. Some sort of "deal" could perhaps get him a pair of Ecofan speakers and they'd hear a good 25 and 40 hertz for a change, and we would all be much happier! I guess...
Here is a photo of an amp.
That booming was pretty traumatising. My friend Sue next door, who's house is right in line with their boomers was quite distraught, and was very appreciative of my managing to mitigate it somewhat for their following day/night blast.
I could invite Arthur over sometime to sit under the trees and listen to my little outdoor JBLs around the other side of the house. He could hear the lovely bass-lines of some of the same bods he plays. Who knows what the Summer will reveal...
If I play something believable like guitar or a piano trio and go for a walk along the road, from the other side of the nearby intersection (in line really through the trees) it does sound like a live performance. Which you hear from the street around here, as in this street there are a few schools with halls for hire, and the bands hire them for band practice. During the weekends. They always sound good.
P.S. "Is that a string quartet I hear playing in the bushes?"
The above amp was in a feature in a local architecture magazine (Urbus). I have no idea how he got it up there, as it's about as much as I can lift!
and he/she uses Technics turntables as well.....nice :) Ecofan and Technics :rave:

But what are those speakers? Looks like something from a nightclub (to match the Techies! ;)) but possibly Tannoys? (Don't think so, but not sure, maybe it is a PA rig) :scratch:
Pass :scratch: over to you Jack ?
Regards D S D L
They are in fact Tannoys, but I have no idea of the model. For the photo they removed the cables!
Here's a photo I took today just to bug the younger generation.
