From the vendor

Another banger from the archives of Run Off Groove.

Here we have an emulation of the tones of mid-late 60's Marshall EL84-based 18 watt practice amps.

Not much more to say, other than it does the job nicely.

There's some fine bias tweaking to be done, so a multimeter is essential for this build.

Supplied with board-mounted pots with round shafts, so you'll need set-screw fitting knobs).

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is only available with full kits, and won't take a battery . Knobs are not included.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.

Inspired by: RunOffGroove Eighteen

Difficulty: Medium

PCB size: 50 x 42mm
