Now that your amp is together and working, here are a few good hints to keep it up and
running and everyone safe and happy:
–
Only plug this amp into properly grounded (three prong) AC receptacles.
–
Do not cut off the third prong of the power cord plug thus defeating its safety feature.
–
Plug this amp into properly wired AC voltages.
–
Do not expose this amp to high levels of moisture such as rain or spilled liquids.
–
Avoid placing any beverages on the cabinet.
–
Whenever changing tubes or cleaning this amp, disconnect the amp from the AC
power source and allow the amp to cool for 10 min. before beginning.
–
It is recommended that the amp is only plugged to AC power when the amp is being
used. Otherwise, it should be left unplugged from AC voltages.
–
Avoid exposing this amp to elevated temperatures such as heaters or hot cars or
garages. The expansion and contractions of these temperatures will put undo stress on
all the solder connections, possibly damaging them.
–
Always provide adequate ventilation for the tubes and amplifier. An air space of 6” or
more is recommended between the amp and any other object(s), especially around the
rear of the amp. It is a good idea to keep the amp as cool as possible.
Amplifier Feeding
As with any tube amp, the choice of tubes will affect the overall tone of the amp. And of
course, some tube choices are more dramatic than others. Therefore, I encourage everyone
to shape the tone of this amp to suit their tastes through the use of different tubes. Below is a
short list of tubes that can be used for adjusting tone performance without modifying the amp.
Preamp tubes:
–
12AX7A / ECC83 / ECC803 / 7025; (high gain – amplification factor = 100)
–
12AD7; (high gain – amplification factor = 100)
–
12AT7 / ECC81; (high gain – amplification factor = 70)
–
12AY7; (med gain – amplification factor = 40)
–
12AU7 / 5814 / 6189 / 5963 / ECC82; (low gain – amplification factor = 17)
–
12AZ7; (med gain – amplification factor = 60)
–
12DW7; (mixed gain – amplification factor, first triode = 100; second triode = 17)
–
5751; (high gain – amplification factor = 70)
Power tubes:
–
EL34 - 6550 - KT77 - 6L6 / KT66 / 5881 / EL37 (w/ slight amplifier
modification. Contact me for more information – tech@tubedepot.com)
Rectifier tubes:
–
GZ34 - 5AR4 - 5R4 - GZ37
Applications
The laboratory environment is nice, but life experiences are better. Time to play.
Keith Relf of “The Yardbirds”, Leslie Harvey of “Stone the Crows”, and John Rostill of “The
Shadows” all died of electrocution while playing their guitars (Leslie Harvey while on stage).
Proper grounding is more than just important … it can be life or death!
