phrases and terminology used in the original manual
“App.” is short for “Apparat” meaning Apparatus or Device. The main speakers are denoted App. because the
Huldra 8-56 has a speaker pair integrated into the Apparatus, and Tandberg must have decided to use the same
names and markings for 8-55 and 8-56.
“Sep.” means t
he other/secondary/separate speaker pair.
“LF
-Forsterker
”
means low-frequency amplifier. The name is selected to distinguish it from the tuner high- and
medium frequency (MF) amplifiers. The LF-amp. takes line-level signals from the MF amplifiers, tape recorder or
record player pre-amps and amplifies it to speaker level. The tone controls are implemented in the LF-amp
feedback loops.
“Program”
means input source, i.e., radio, tape recorder or turntable
“Klasse B” The manual says the amplifier is class B. The service manual (from which the below illustration
s are
taken) actually says that the amplifier power stage is single ended push pull and works in class B. The
terminology has obviously changed. In modern terms, it would be more correct to call the H8 power amp a class
AB quasi-complementary push pull amplifier (with a 30 mA quiescent current.) The 12v 18W lamp seen below
acts as a fuse and lights up if the speaker terminals are shorted.
