Important Information:
1.
Please read all of the information contained in this document.
2.
HUM - Some hum or amplified noise is normal. As the volume is increased
some amplified noise may be noticeable and will be more apparent in a small
quiet room. Additionally, tubes have inherent noise as do resistors. However,
excessive hum (noise) can be caused by electronic devices located near the amp
or on the same circuit such as neon signs, fridges, fluorescent lights, computers,
light dimmers, aquarium pumps, etc. Hum can vary with different outlets,
rooms or buildings.
3.
Do not operate this amp without a speaker load.
4.
This amp is equipped with a 1 Amp Slo-Blo fuse. (I know the controls panel
says 2A Slo-Blo but it’s a mistake on the panel and will be corrected in
subsequent builds.) If a problem develops with the amp, the fuse will open and
the amp will not operate until it is replaced. After replacing the fuse, if the amp
does not operate or continues to blow the fuse, the amp needs service.
5.
This amp is fixed bias. If the output tubes are replaced the amp will have to be
re-biased for the new tubes. The bias range resistor will need to be replaced to
set proper bias for the new tubes. This work should be done by a qualified
technician.
