It may have been the right combination of price, power, features and styling for you. It may have been because you know the Manley Labs reputation for quality, reliability, and integrity. If any or all of these were the reasons, you made a good choice and for that, we thank you.
If you have no idea why a fuse might have just blown on its own, you might want to consult with Manley Labs or your dealer for further advice as Something Very Bad might have occured, like the power transformer might have decided to retire early.
OPERATIONAL NOTES PREPARATION FOR INSTALLATION Budget a suitable space in which to place the amplifier and associated interconnect and mains power cable. This space should be free of strong external magnetic and RF fields, and reasonably removed from strong loudspeaker- generated acoustical fields.
(vinyl!) you will need a separate phono preamp to raise the level from the tiny signal from the cartridge, and apply the RIAA EQ curveso it will become a regular line level signal. The Manley Steelhead is a lovely choice for this application, for example.

5. Connect the speaker leads to the terminals on the top far left and far right of the Stingray. Be sure that the RED (+) positive terminal is connected to your positive (+) wire and the NEGATIVE (-) (white or black) terminal is connected to your (-) Negative wire. Connect the opposite ends to the speakers also RED (+) to RED (+) and Negative(-) to Negative(- ).
Troubleshooting: It is rare that any of these problems occur but if they do here are some things to try. HUM - Try a mains ground adapter if they are legal in your country. Or try one anyway unless you fear the Electricty Police.
FRONT PANEL A - BALANCE - This is a special Noble balance control. Unlike most balance controls, this one has no loss at center (detented) and can be considered to be a straight wire if it is in the 12:00 position. It only reduces the volume of one channel at a time B - VOLUME - This is also a high quality Noble conductive plastic precision attenuator.

The Rear Panel Controls: In the summer of 2005 we added a bunch of features to the Stingray production version 3 that previously were available as add-on individual options. Read on to learn how to make the most of the Stingray in your system. Please note that when we describe an "input"...

LOOP RETURN- This input comes in after the Input Selector and just before the Stingray's Balance and Volume controls. If you have all your sources going into another external preamplifier, or even a Home Theater surround processor, then you could plug that preamp's outputs here and let the Stingray just function as a stereo power amplifier when the Loop switch is set to Loop Active.

SPEAKER POSTS - The speaker connection posts are on the back side panel and labeled on the top panel. The RED is positive and WHITE (or black) is negative (ground). Be sure you have speakers (or a 4 to 8 ohm load resistor) connected to these terminals before powering the Stingray.
Optimizing Your Sound System This section is full of little hints that may help you get the most out of your stereo - and it may not cost anything or cost very little. Probably, you know most of this, but hopefully some of it may be new or refresh your memory or just be refreshing reading in a manual.

You may have bought a great system but there is a good chance that you are only getting a fraction of it's potential. Very frequently we have experienced top quality electronics sounding unimpressive simply because acoustics were ignored. Even amongst studio engineers, few can really tell the difference between good speakers in a bad room and bad speakers in a good room - but they all know good speakers in a good room and very likely so do you.
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.
More silly vacuum tube questions... FAQ #16f. Should I turn off my gear between uses? While power cycling is a factor for ultimate tube life, there also is a fixed number of electrons that can ultimately jump off the cathode. In general we do recommend if you aren’t using the gear for more than a few hours you should power it down.
What should I know about BIAS? Bias is a simple DC (negative) voltage that sets, what is called, the "operating point" of the tube. For our purposes it "fine tunes" the current going through the tube. We want each of the 4 tubes per channel to be equally sharing the load. This gives the amplifier's lowest distortion and the tube's optimum life.
It all began at the HI-FI '97 show, at the bar of course -J. Gordon Holt with his traditional martini, and EveAnna Manley with her stimulant of choice, a cup of coffee. She was describing this new integrated amplifier she wanted to build and drew a one of those legendary "bar napkin drawings".
