Well, I need an amp for my college jazz band. I always wanted a Roland JC, even before I played much jazz I thought they had the best clean tone ever. I have an idea vaguely sort of similar to the JC, two totally separate amps each running into a separate speaker, each voiced a little differently for a nice stereo effect. I came across this

and my tentative plan is to build two poweramp sections with these, using something like this

for each of the two preamps.

I found these, will they work for what I want to build?

Any AC non center tap step down transformer with a secondary of 24-30v will work, right?


Here is my current bill of materials, am I forgetting anything?

(for poweramp)
Resistors (1/4 watt rating)
1 – 4.7 ohm ½ watt
1 – 680 ohm
2 – 22k
ICs
1 – TDA2030 or TDA2040 ammp IC
Capacitors (minimum 20 volt rating)
3 – 0.1uF film
1 – 1uF aluminum electrolytic
1 – 22uF aluminum electrolytic
2 – 220uF aluminum electrolytic
Other
2 – 1N4004
24 gauge stranded wire

(for bipolar supply)
Capacitors
2 – 1000uF Aluminum Electrolytic
4 – 0.1uF film
Other
2 – 1N4004
3-way power jacks/connectors
2 – Regulator Heat Sinks
Thermal Compound (heat sink grease)
22 gauge stranded wire
AC Cord/plug
2 – sets of nuts and bolts to bolt down the
regulators or to bolt the regulators to the heat
sinks.
heat sinks
110v in 24v out transformer (1.25A okay?)
2 10" speakers
Chassis
Cabinet
And I have all the stuff I need for the preamp.

Thanks, this looks like a great forum!
