Nice and sunny. It comes back every spring all nice and green, then croaks. ****es me off. But it doesn't get a chance to go to seed so it has to be a perennial strain of something. The **** grass is what goes to seed generally, the annuals. Most desirable turfgrass is perennial and never goes to seed because you cut it every week. It never gets tall enough to produce seed... like corn. If you see grass that's only 2 or 3 inches tall going to seed it's more than likely an annual grass. It's considered a weed in most parts and people will pay to try and prevent it. Golf courses hate it. I'd have to see it to know. Yeah if it's sunny there you might consider sowing some turf type tall fescue or some sort of a perennial blend rye/blue/fescue. If it's shade go more with the fine fescue/rye blend. I'm definitely saving this post.... Thanks!!! Glad to help. That's just a stab in the dark but it might be the problem. It's real common here. We slice seed those areas for people in the spring and fall. I let my fescue get tall enough to go to seed a couple of times a year. I have a neighbor who really hated this and she let me know in her catty way. Funny thing the rest of my neighbors found out what I was doing now they are too. I told her it was a good thing we didnt live a little further south. Then she would have to put up with me burning off my St Augustine every couple of years. Why would you burn off St. Augustine? Burn it off in the winter while it is dormant is the easiest way of getting rid of the thatch. If you dont do it it will eventually choke itsself to death. When this happens you get a big bald spot in your yard then the grass fills in again. In other words if you dont dethatch it it will dethatch itself in very ugly ways. |

OOO crap did any one notice the class d amp WAS running off the 120V line
input NO Isolation to the Finel D amp section to the speakers, WOW SHOCKING. "james" wrote in message ... On Thu, 04 Jan 2007 18:17:51 -0800, Frank Gilliland wrote: +++No kidding.

I know there are mechanical ways of doing it but to me they are a lot of work and rip out the roots. |

Scalping with a lawnmower in the very early spring is the most common practice, while it is still semi-dormant. I suspect the city and the neighbors would object to burning.

There bigger is definitely better. james Not to uncommon for a design that WILL work of of line voltage to not show a transformer even though it should have one. This may be in the verbal description of the AMP. Also any High Power amp may have a couple of hundred volts DC on the speaker terminals if there is componet failure. There should be circuitry to prevent this.whether it is line isolated or not. Typically the protection circuit CROWBARS the power supply blowing the fuse(s). Again it is not uncommon for something like this to not be included in the draft copy of an amp design. |

No, where this stuff grow it seem like everybody burns it or doesnt have it. At least thats been my experience. |

Again it is not uncommon for something like this to not be included in the draft copy of an amp design. You're right, and I think I remember saying that it was a prototype. The production version was a 2-channel unit that included a better front-end with clipping indicator, a triac power switch (easier on the power lines), a DC offset protection circuit (no crowbar), and thermal breakers on the sinks. It was conservatively rated at 1000 watts RMS continuous into 2 ohms in bridge mode. It could do 2000 watts but the filters would get too hot because of the low carrier frequency, which was the primary limitation of MOSFET technology at the time. Nowdays they make MOSFETs with rise times in the sub nS range which made this amp obsolete very quickly. |
