INPUT TUBE INFORMATION

The SE84C is designed to use your choice of

three different input (or signal) tubes.

6N1P (a Russian tube from the same factory

that makes the SV83 and 6P15P-EV)

6DJ8 (a popular low noise tube both available in

current production by numerous manufacturers

and in N.O.S.)

6922 (a popular variant of the 6DJ8 also avail-

able by a wide variety of manufacturers and in

N.O.S.)

RECTIFIER TUBE INFORMATION

The SE84C is designed around the 5Y3GT recti-

fier tube. It is however, compatible with the

following alternatives - each having a subtle ef-

fect on the overall sound characteristics of the

amp.

◊ 5U4

◊ 5AR4

◊ GZ34

◊ 274B

The different ratings and efficiencies of these

rectifiers will effect the operating voltage points

throughout the amplifier which is why they can

have an effect on the sound. You will find that

even different brands of the same tube will

sound different. This is true with any vacuum

tube.

The sound is typically warm with good balance.

The sound is more airy and detailed, less bass.

The sound is typically more dynamic and detailed.

WHERE EVERYTHING GOES

Below are the tube locations, input jack con-

figuration and power switch location.

The input switch, one for each channel,

changes between direct and variable inputs.

It always points to the active jack. For ex-

ample on the left side of the amp, moving

the input switch to the right would select the

variable input for that channel. Variable in-

put means the signal goes through the vol-

ume control located at the front of the

SE84C.
