Electrodrone ZB50 Amplifier

| July 28th, 2012

Our friend Scott Hodgson (Electrodrone) designed and built this very nice 50 watt high-gain amp for us in 2006.

He named it after this freaky 80s Honda motorcycle:

Tube complement

2x KT77 outputs/12AX7 preamp/12AU7 phase splitter

Features of note

Matching 2×12 cabinet with old Altec 4178H alnico speakers

Half volume switch (built-in attenuator)

switchable midrange cut

Construction

Here’s the chassis during its final stages of testing:

Scott’s father is an ace carpenter so we hired him to build the head and speaker cabinet enclosures. He used baltic birch.The finger joints fits together perfectly.
