FRONT PANEL, PANEL DESCRIPTION 

1.

POWER 

This switch turns the amplifier on and 
off. The amplifier is off when the switch 

is in the position “0” – then the switch 
is not illuminated by the internal lamp.  
The amplifier is on when the switch is 

in position “I” – the switch is 
illuminated in red. In this position the 

amplifier is muted, but tubes are hot, 
and you can change channels. 

HINT

:

Before turning the amplifier on, 

always make sure that the Standby 
switch is in the position “0” – this will 

extend the life span of the tubes. Turn 
the amplifier on the following way: 

first, turn on the Power switch and wait 
about 1 minute. Next, you can switch 

from Standby to I or II. 

Turning off the amplifier works the 

other way around. First, switch the 
Standby  switch  to  “0”,  wait  about  1 
minute and then  you can turn the 

Power off. 

 
2.

STAND BY 

In position “0” the amplifier is ready to 

work. Changing it to positions “I” or 
“II” sends anode voltage to the tubes – 
in these positions the amplifier plays. 

You have to wait about 1 minute for 
the tubes to get heated before 

switching. 

In position “I” – “Diode” – diode 
rectification is used, however, in 

position “II” – tube rectification is 
used.

HINT:  In position “I” there is more 
response

and dynamics – the sound is 

more aggressive and “fast”. Position 
“II” has a more compressed sound and 

slower attack – vintage like sound. 

 
HINT: If the amplifier is only used in 

Diode mode, the rectifier tubes V9, V10 
can be taken out (see page 13) – the 

amplifier will use less energy and  the 
removed tubes will not be exposed to 

vibrations while the amp is in use. 

 
3.

50/100 wat 

Change of the amplifier’s output power. 
In position “50W”, only the tubes in 

position V5 and V8 are operational. 
       In  position “100W”, all the 

5851/6L6WGC tubes work. 
 

HINT:  Switching to 50 watts causes a 
decrease in dynamics - so called 
“headroom”, understood as the space 

between the quietest tones and the 
loudest ones - the amplifier has more 

tendency to distortion.   

HINT:  If the amplifier is always used 
in 50W mode, you can take out the 

central     tubes V6, V7 (see page 13) 
and keep them as spare for the future 
– the amplifier will use less energy, 

and, taken out tubes, will not be 
exposed to vibrations while the amp is 

in use.
