HEADPHONE LISTENING
If you are using headphones, the amp only accepts 4-pin balanced male
connectors. A 4-pin XLR to ¼" phono adapter can be constructed by shorting
pins 2 and 4 of the XLR into common for the phono jack.
SPEAKER LISTENING
If you want to drive speakers you will need a pair of Neutrik NL2FX Speak-Ons.
(The Neutrix can be ordered at Mouser Electronics located in most countries;
part # 568-NL2FX). When hooking up speaker wire loosen the 2 screws almost
all the way out, insert wire and tighten screws. When connecting speaker wire
to the Neutrik Speak-On, first disassemble the connector. Looking at the rear of
the connector there are two screw terminals where the speaker wire is attached.
The right screw terminal is speaker positive. Insert connector with release tab at
8:00. Twist clockwise it will lock into position at 9:00. To remove press thumb
tab backwards and twist counter clockwise. You can also refer to the Neutrix
website for additional help if needed.
The tubes for the Aficionado are one 5AR4 rectifier tube, one 6N3P tube and two 2A3
tubes. The 5AR4 tube may be substituted with the 5Y3 or 5R4 rectifier tubes, but no
other tubes are recommended. The 5AR4 is recommended as it has the least voltage
drop among compatible tubes.
The 6N3P may be substituted with the 2C51, 5670, 6854, 398A. No other tubes are
recommended. There are many different 2A3 tubes available. If you wish to change
tubes, disconnect the power. Be extremely careful when inserting in the new tubes.
Make sure the pins are straight and you push the tubes in correctly - it's easy to bend a
pin and the tube will not insert. If wrong type tubes damage the amp, the repair is not
covered under the warranty.
Such an adapter will cause damage if used on other balanced
amplifiers with two amplifiers per channel running a differential
signal!
