Tube “rolling” and replacement
.
Only the front pair of matched 6N8S valves can be replaced with the same type or 6SN7,
6SN7GT or 5692 or CV181.
Please note: The protective cover will not fit over the taller CV181 valves.
Use of any other valve type will damage the circuit and invalidate the warranty. In case of
“valve rolling”, the use of octal valve socket savers is strongly advisable, as any damage to
the valve sockets caused by “valve rolling” is not covered by the warranty.
The matched pair of 6N6P should be replaced with the same type only. The pair of EZ35
rectifiers can be replaced with the same type or 6C5S, CV574 or 6X5GT rectifiers.
IMPORTANT!
Fuse.
The unit is fitted with a
1A
fuse which is located in the IEC mains socket on the back panel –
this must be replaced only with the same amperage value!
(a spare is provided in the fuse
“drawer”). In case of subsequent fuse failure – the unit has to be send for repair
Earth
connection –
the
unit must be earthed
, this is provided by the safety earth contact in
IEC mains socket – make sure that your home mains electrical installation has safety earth
connection in order.
Removing the Valve Cover.
The valve cover is secured to the top of the unit by way of 4 hex bolts being accessible
through slots in valve cover. The cover may be removed in order to facilitate tube
replacement by using the supplied long hex key (2mm) tool to undo such bolts.
