Raising planar's off the ground helps a lot with any bass abnormalities. The manufacturers won't build the speakers like this since they are tall enough already but roughly 20-30cm will give a lot of improvements.

Indeed.

Ahh ok. Never had a EL34 give up the ghost completely...

Did you break one of the EL34's or something?

Guess I'll have to sleep with a knife under my pillow now. Stupid gun laws...

Woot!!!

Happy Birthday!!!

It is possible to reseal the drivers but it's far from easy. You need to strip them down and get rid of all the old glue residue and then assemble them again with polyurethane glue.

I'd open up the housings and see if the drivers are not coming apart. That can happen with some of the older phones. They should be firmly glued shut. Also look for any gaps in the mylar dustcover on the front or the one on the back.

Clearly bias related but what exactly is going on is hard to say. Could be that the phones have arced and there is some residue on the diaphragm causing it to act up. No way to open up the drivers to check though.

Tell me about it, plenty of projects to finish and I have to find a SR-007A to mod...

There are many variables at play here, the breakup frequency of the drivers being the number one culprit. Power isn't really a factor here as that is more dependent on damping and the electrical characteristics of the driver which change very little as you alter the tension. Even though the mylar is "loose" it doesn't move a whole lot, rather it vibrates.

My guess is a different driver (mylar tension that is) but the only way to confirm this would be to get our hands on replacement drive units as they would be clearly marked. As for the cryo, I'd file that under marketing and nothing else.

Yup, it's a part of the whole rape and pillage thing we do so well.

Flipping

The small ones usually don't have a split volume know but some do have a built in balance control. What we could use are detailed pics of the circuit to see if you can take some measurements to see what's going on.

The cable has a copper core but a thick layer of silver on top of that, similar to what APS and others are doing. It's probably a fine cable but I don't buy into that it has changed the sound this much. I'd rather say that the SR-404LE uses the same drivers as the SR-SC1 and thus sounds more like the older phones. The thinner pads might make a difference but on the SR-404 I modded I also used the newer, thinner pads and they sounded pretty much the same. I would like to try the cable on a SR-007 though...

Happy Birthday!!!

DIY time!!!!

1K$ worth of transformers...

Well that and we just eat fast food most of the time. There are 12 Subway's in Reykjavik, 4 KFC, 7 Domino's, 3 Pizza Hut and the list goes on and on in a city of 200.000. That's not a bad piece but it reflects the atmosphere of the time it was written in. After a year of what could best be described as parts of Orwell's Animal Farm things have moved on a bit.

I was thinking more about sugar glazed...

Yup... Truth be told that guy got to see us at our worst, protecting our survival by extending the protected waters around us in the Cod Wars.

Does is make you feel better Doug that it is 4

Want me to bake you one? Bread would a great material for the tube.
