Congratulations on your purchase of a STUDIO HAVOC power
amplifier, hand-built and hand-wired by Finkbiner Industries LLC in the
USA. The STUDIO HAVOC power amplifier features one 12AY7 tube

4. FUSE
The power cord receptacle contains a fuse for protection. Only
replace the fuse when the power cord has been disconnected,
and only with like specifications (see SPECIFICATIONS on page
7). If your amplifier is blowing fuses, send it in for service (see
SERVICE AND SUPPORT on page 3). Do NOT replace with a
larger current rating fuse.
5. SPEAKER OUT
Accepts a 1/4” TS connector, and sends a speaker level signal to
an 8Ω speaker cabinet.Be sure to use an appropriately sized
speaker cable (16 AWG is fairly standard for typical cable
lengths of ten feet or less to 8Ω speakers), NOT a guitar cable.
6. LINE IN (UNBALANCED)
The STUDIO HAVOC power amplifier has a single high(-ish)
impedance (100 KΩ) input for use with line level signals from a
HAVOC preamplifier, stomp box, mixer, or other device. The
input jack accepts a standard 1/4” TS guitar cable.
