OTHER CONSIDERATIONS
Suggested Speaker Systems – Your speaker system should be chosen to
accommodate the characteristics of your amplifier and your predominant
application. If you will generally be using two cabinets, they should both be
8 Ohm models so their combined impedance will be 4 ohms. If you are
uncertain about your future needs, always go with the 8 Ohm speaker option
so that you can add another speaker later if you need to. In general, adding
more speakers will give you a greater volume increase than adding a few
more watts.
Using the VT300B Without Speakers -This amplifier is NOT designed to
be used safely without the loud speaker plugged in. Doing so will cause
serious damage to your amplifier. We keep saying this because it is so
important.
MAINTENANCE
Your Eden amplifier has been designed to require minimal routine
maintenance. Attention to the following areas will ensure optimum
performance of your amplifier. We’re serious. Don’t blow this off, OK?
Tube Maintenance – Tubes wear out. It’s just the nature of the beast. So
it’s a good idea to occasionally check that all tubes are operating normally.
If this is your first tube amp, it’s a good idea to look at the power tubes the
first few times you operate your VT300B. This will give you an indication
of how they look when operating correctly.
If you ever see one or more tubes glowing a different color, it’s time to
replace your tubes. For example, if a tube is glowing red, this means the tube
has failed completely. If this ever happens, immediately shut down the
amplifier and replace the bad tubes.
REMEMBER: Tubes are electro-mechanical devices and can fail due to
excessive shock or vibration. If you drop your amplifier, don’t be
surprised if the tubes are damaged.
