This is the Hoffman Stout board kit. This is an 18W board kit designed by Doug Hoffman.
You can read more about the Stout here:
Hoffman library page
under "18 Watt Stout".
The board comes "stuffed" with all components soldered in place via the standard "Hoffman" turret lugs. The board has a bias pot installed for bias adjustment, and comes in two versions from TheAirtightGarage, standard and upgraded. The standard version comes with all of the "stock" parts: carbon composition signal resistors, precision flameproof resistors in the power section, signal caps chosen for tone (Sprague, Poly, Mallory). Sprague or other high quality electrolytics are used in the cathode bypass.
The upgraded version consists of the same components as the standard version but the signal capacitors are replaced with high quality film in foil types.
Both versions use silver wire for the bus connections between turrets, and include the following:
- Potentiometer harness with Alpha pots
- cloth covered colored wire
- shielded input cable
- standoffs and mounting screws
- switchcraft inputs jacks and input jack resistors
- ring terminals for ground connections
- heat shrink tubing for shielded cable
- Grid resistors for output tubes
You will also receive the Hoffman install manual, and some "tips and tricks" notes from TheAirtightGarage to aid in installation.
Chaissis, knobs, transformers, cabinet, speakers, tube sockets, tubes, switches, and "everything else" not included. You will receive the Hoffman board and the associated parts listed above.
