AFICIONADO
Congratulations on your purchase of the Eddie Current Aficionado vacuum tube
headphone/ speaker amplifier amp. The amp’s unique audio circuit, combined with a
passive CLCLC filter power supply delivers the Holy Grail of a high fidelity experience,
delivering a sound stage designed specifically to maximize the 2A3 electron cloud. On
a quest to bring back classic tube-driven audio, the Aficionado is cap coupled through
an old school Russian military toxic oil, paper, and aluminum foil capacitor. Output
transformers are machine wound by CineMag Inc. The end result is an updated modern
version of classic American audio design!
SHIPPING CHECK
The Aficionado is shipped in 2 boxes, one for the main amp and one for the power
supply. Upon receiving both boxes, check for shipping damage by: 1) Gently rocking
the amplifier back and forth listening for anything that may have come loose in
shipping. 2) Making sure all the screws are tight. If you feel something was loosened in
shipping, please contact Eddie Current for further instructions. Most issues can be easily
corrected.
PREPARING THE AMP
Your amplifier has been set to run on the requested voltage. Before setting up the amp,
check to see if your line voltage agrees with the box checked on the power supply rear.
If not, contact Eddie Current before continuing. The power supply umbilical cord is
attached at the power supply end. Place the power supply at least six inches from the
amp. Plug the umbilical cord into the power plug on the amplifier rear panel. Line up
the umbilical cord connector notch with the chassis mount male connector key at 12
o’clock. Be sure to insert the connector holding the metal connector end, and not the
cord, this is even more important removing the cord. Do not pull off using the cord.

TUBE INSERTION
Insert the tubes with the one 5AR4 rectifier tube going in top the power supply socket,
the one 6N3P tube into the front main amp socket and your two 2A3 tubes in the
main amp matching sockets. Your 2A3 tubes should have two large and two small pins;
the large pins face the rear. Be sure to align them to plug in correctly.
Please note if you are using the 2A3B Shuguang there is usually solder residue on the
pins which can be
gently
sanded down for better insertion. However, even if the pins
are not fully inserted, they will still make sufficient contact as-is. Once tubes are
properly inserted, you may plug in the power cord.
Important! Do not turn the power supply on unless all tubes are in their proper
location, and the umbilical cord is connected. Once the amp is turned on, you may
hear a low level shimmering sound from the output tubes for about 10 seconds. This is
normal, and varies with tube manufactures. It takes about five minutes for the amplifier
to completely warm up, and sound its best. You’re ready to listen! Should you have
OPERATION
Please refer to diagram below:
Select the source by rear panel switch. All outputs on the back (and the headphone
output) are simultaneously active unless the speaker kill switch is active. The speaker
kill switch only disconnects output to the speakers.

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.
Such an adapter will cause damage if used on other balanced
amplifiers with two amplifiers per channel running a differential
signal!
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.
TUBE COMPLIANCE
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.
