PROJECTS AND TOYS FOR THE (SERIOUS) BOYS
NOTE these items are for engineers or qualified people, and are really cheap for what they are. But please only buy them if you can: a) read and also interpret a circuit diagram, and b) have a fair idea of the topology of the design and how it works. Absolutely NO Brain picking, Night school, or Psychic analysis service on these items at all. THEY ARE NOT AIRFIX KITS with step - by - step instructions.
 
Build a Guitar Preamp.
Gain switchable, with distortion, bass, middle, treble,reverb, and master volume. Pull bright, pull heavy, pull smooth facilities. All sockets and pots fit on the board. Bare pcb and circuit diagram - £3.50 - Was used on the old HH L50
 
Build a Graphic Bass Preamp

Active and passive inputs. Gain, Bass, Treble, Compressor, 6 band graphic, Master volume, Bal. DI output. All sockets and pots fit on the board. Bare (2) pcb set, 6 correct slide pots and circuit diagram - £9.95 - Was used on the old HH B100
 
Build a 50 Watt power amplifier.
Uses a pair of TIP132/137 Darlington transistors, and has power supply components, line jack, and headphone socket on board. Bare pcb and circuit diagram - £1.50 - Was used on the old HH B50/L50/K50
