To maintain the sound quality we recommend the
valves be changed every 2-5 years* to maintain the
full sound quality. A new set of valves will give you
back
a “NEW” HP 205D amplifier!
(* depending upon
use and not withstanding valve failure).
Icon Audio can supply a new set of valves which are
ideal for the HP 205D ranging from standard to
“premium” types. The will be matched and tested for
quality, and audio tested again to check that they are
sonically perfect.
It is essential that only the correct valves are used as
some similar looking valves have a different pin
connection and insertion could result in damage to
the amplifier and risk of electric shock. 5U4/5Z3
rectifier is not suitable.
It is not good practice to remove the valves
unnecessarily as this can strain the pins and cause micro
air leaks. Icon Audio are happy to check valves and
check the performance of your amplifier, and advise on
the latest upgrades available FOC.
Method:
Switch off, disconnect from mains and allow to stand for
10 mins to allow voltages to discharge. You should
carefully remove the valves, these should be held by the
base when removing to prevent damage. Care should be
taken when removing and inserting the valves. The
rectifier valve has a centre location
“spigot” observe
correct orientation. Do not operate without valves!
CAUTION
– HEALTH & SAFETY!
When making any adjustments remember to isolate
from power supply, and remember that high voltages
can remain present inside for some time after switch
off.
Service:
Should you suspect a problem you could return
the unit to your dealer or Icon Audio for a periodic service
or return the valves for testing free of charge. You should
carefully remove the valves they should be well packed in
cardboard & foam or similar and returned to Icon Audio.
(Valves are very rugged if packed properly).
