First, read the orange glow question above. Is the color you're seeing orange, coming from the top and bottom of the tube's "guts"? If so, you're OK. BUT... if the plate, or any part of it, especially in a power tube, is actually glowing red (even a faint red) shut the amp off at once and find out what the problem is. Otherwise, you will certainly destroy the tubes. You could also destroy other parts of your amp, resulting in a huge expense to repair it.

Have a careful look. If there are patches of blue glowing on the glass, probably with fairly sharp edges, it's due to electrons missing the anode and hitting the glass instead, making it flouresce. (Most of the tube envelope may even glow. -ed) Quite pretty, and you can play for hours, moving the patch with a magnet... (Don't electrocute yourself!) This kind of glow is common with beam tetrodes and is completely harmless. (This type of glow is by far the most common.

This is not only normal, it's a requirement of tube operation. This glow normally comes from the tube's heater, or filament, which heats the cathode so that the tube conducts properly. If you don't see this, and your amp doesn't seem to be working properly, check the amp in the dark (some tubes, esp. Sovtek 12AX7LPS tubes) have a filament glow which is very difficult to see. If you still aren't sure, let the amp warm up for a few minutes. Then, place a fingertip near each tube in turn.

No, you don't have to toss them just yet. However, a blue glow indicates the presence of some gas in the tube, which is not a problem in most situations. If you have noticed an increase in the amount of blue, then you might want to get a new set of tubes sooner than later. Too much gas in the tube can lead to bias failures, blown fuses, and possibly blown output transformers.

The short and simple answer is YES! However, achieving the same effect requires a combination of several factors: The LEDs should have as wide a viewing angle as possible. This will allow the light from one LED to "melt" into the light from surrounding LEDs and make them appear as a single, continuous light source. The LED string should be placed a reasonable distance away from the object to be lit.

Red Steel is a setting that is part of Mystara (west of the Known World), although it was released as a stand-alone setting. I have a player of the Church of Karameikos, and I want to give him an Immortal, I suppose that it's a church with many Immortals (like the Greek / Latin church) but in Gaz 1 I didn't find any list of Immortals..

Its not red. Its maroon. Would you prefer orange instead? I don't like white backgrounds. And it was a choice between black and pink. I flipped a coin, and it flew majestically in the air and landed in the crack of my keyboard. I then took the liberty of taking the mix between black and pink - maroon.

Yes, the turbo/exhaust manifold can glow red under certain driving conditions. The exhaust gas temperature can reach over 1600F under high load operating conditions; i.e. towing, extended uphill driving, or extended high rpm/boost conditions.

Most of the time, otitis media clears up with proper medication and home treatment. In many cases, however, further treatment may be recommended by your physician. An operation, called a myringotomy may be recommended. This involves a small surgical incision (opening) into the eardrum to promote drainage of fluid and to relieve pain. The incision heals within a few days with practically no scarring or injury to the eardrum.

Answer: While NingXia Red™ Juice is indeed a potent (non-diluted) blend of 5 fruit juices, it is as safe for children as eating a wholesome fruit cocktail. In fact, the NingXia Red Juice promo DVD concludes with Gary Young's 3 year-old son downing a 2 ounce glass of the juice. However, while it is always safe to drink NingXia Red™ Juice in small amounts, many adults and children prefer to dilute it (like other juices) by adding 3 parts water to 1 part juice.

All of these tubes are made right here in the U.S.A. The tubes are manufactured and shipped very close to Salt Lake City, Utah.

Normally we are able to successfully process samples submitted in these other tubes; however, often special handling is necessary which delays the results. Our typing methods have been optimized using the Zoogen submission kits, so the fastest turnaround will be obtained when your sample is submitted in a Zoogen kit. In particular, please note that heparin, which is the anticoagulant in the green top tubes, can inhibit the PCR reaction so it is best to avoid using these tubes.

Get a Hatori SB-8, it really sounds great! Other options are Weston Genesis Pro pipe and the KSJ speed 30 tuned muffler Another possibility is that if your struts have worn through on the bottom like mine, then the skids might be loose enough to vibrate against the set screws. Also the screws that screw the tail boom support rods to the horizontal fin are just a little long. Use a dremel cut-off wheel to take off the last 1/16"-1/8" from the screw.

That depends on the chemistry of the plastic molecules that make up the scintillator material. However, the scintillator material is engineered to produce a fairly pure color (wavelength) of light, and a color that can be easily detected by the photomultiplier tubes we use.

We are only as good as our worst tube. We are very selective about which tubes we use in Manley products and we have several different testing and burn-in jigs to test for certain parameters which will be most important for that tube in a given circuit. We will test and select a tube set for you that will be optimized for your Manley piece of gear and in most cases, your tube set will actually be tested in another one of what you have.

Not especially. Although I might have made a killing in the stock market had I invested the money I instead put into finding and stocking these large quantities of tubes ten years ago when the USA military were dumping their stocks of NOS JAN vacuum tubes.

Yes, it takes a while to get used to, but you will be able to hit with even more top-spin and back-spin with the moveable mass racket.

The tubes are made of a tough nylon and are protected from wear by the frame. Leaking and migration of the fluid from the tubes is minimal and the fluid will last for many years.
