Schematic from runoffgroove.com. Box is 3.75" x 3.75" x 1.75", external power. I took it down to my friendly music store, we plugged in a Strat, and the little thing drove a 4x10 cab with authority! Inlaid rhinestone just for nice; brass picked up in the street.

<< need to know more whats this thing running on 9v or 110 and how about the board? same local dealer? >>
Just any old perfboard, RS or anybody has it; I don't go for the pre-coated stuff, but your pick. Some like it; let me know how it works for you.
It's using 9v, through a RS 110v-to-9v wall-plug transformer (something like $15). The cool thing is, it comes with a two-connector end with available interchangeable plugs so you can match your plug to the jack - this is a Type "N", if I recall - and you can change polarity! Yay! My Honeytone is a different polarity from the Little Gem, so I just turn the plug around, and 'voila', as they say in Gay Paree. (Or I could always re-solder my Little Gem's jack around to match, but that sounds like work.) This charger over here's got a different jack, so I get another plug, change them out, and I'm good there. What a great little planet!
Here in Eugene, at Norvac, an electronics parts house, for new parts and helpful advice from real humans leaning on the counter. There should be some place similar practically anywhere - check the Yellow Pages and support local businesses when you can!
