garden amp
I found that I enjoyed listening to music in the garden more than in the living room, I hasten to add I can play at any volume ,in the garden that is! There are no neighbours near enough to be bothered by my excesses.To that end I bought a load of 8" bass/mid for a snip on ebay and along with some tweeters coupled them up in a pair of column cabinets to hang on the wall. I decided that due to the fact that I could only use rudimentary and very un-scientific crossovers .I would drive them Via some sort of Graphic Equalizer. It was then I came up with the Idea of putting one of the new breed of Class d chip amps inside a G.E. to make up an integrated amp. I also realised that If I bought a 24V @5 amp printer PSU I would not have to mess around with transformers etc. I actually also fitted the tuner section of one of those little red tuner amps you see advertised for boats and bikes.(the amp chips were blown) They have a PLL tuner chip and given enough aerial signal they perform adequately for this application. I have therefore made a cheap and cheerful Lo-Cost but powerful receiver with the ability to adjust for the speakers main deficiencies. Maybe not Hi-Fi but fantastic stage imaging without all those room reflections. Queen live @ Wembley is breathtaking, It's like Freddie's standing in front of the wall. I tend to like live rock concert recordings like Leeds,and Get your Ya Ya's etc and they really suit this open air reproduction.
Here's a couple of Photo's of the finished receiver.

An externally hosted image should be here but it was not working when we last tested it.

This is the accompanying main amplifier. I built it a couple of months before the preamplifier and I still use it today. Because of the heavier components (transformer, heatsink) I couldn't build it into a tin can (not even a large pickle can), so I used a more regular enclosure. It is a 2 times 20 W (in 8 ohm) class AB amplifier with class AB control loop.

I think it would have had a tinny sound. Perhaps stereo pears would have sounded better.
'In any case', it would have been easier to write on the flat ends, like this X- Can

BTW, has this SARA AMPLIFIER been discussed in this forum or only on its original thread on elforum.ro?
I am a bit curious about it, specially for a comparison with the Honey Badger.
Thnx.
