<p>So that's an option for me to do - Just have the 386 running as a preamp to the 18w power amp. You've answered the question I hadn't asked yet as I did try my preamp with the power module. I got sound through but it wasn't loud.</p>
<p>I did at one point have a 5 channel 100w PA amp with reverb, but it was too loud, and I gave it away. I hate hindsight!!</p>

<p>Just search "10PCS 9-Pin Stomp Foot Switch" there's a few of them. The one's I got are those with the blue body to the switch.</p>
<p>What I usually do is have a quick look at what other stuff each of the vendors have. Sometimes that swings me in to direction of one of them.</p>

<p>My dual chip bridged amp has loads of distortion at 1watt . I can use it as a preamp with a old Radio Shack 20watt PA amp, but I need to get some new speakers for it.</p>
<p>Old PA amps can be found for cheap and make great power amps with the right preamp or pedals.</p>

<p>Thanks Paul,</p>
<p>What I love is the amp with the preamp through the 2*12 cabinet. The overdrive/distortion I get though the small speakers of the amp itself is OK, but through the larger speakers if sounds so good. It's really hard to believe it's just a 1/4 watt driving it.</p>

<p>The most powerful amp I have is a 5 watt tube Fender Champ clone that was heavily modified by someone who knows what he's doing (unlike me). I haven't tried the preamp through that yet. There's just so much to play with and explore.</p>
<p>I've also got a couple of Chinese 18watt power amps that I want to try. They are small enough to live in the same small tin box as the preamp, and I just love the bizarre idea of having an 18watt amp that can play clean or distorted in what's essentially an Altoids tin.</p>

<p>Nice amps. I've found that these little 386 chip amp sound great through big speakers. Made a Ruby amp and put it into a Behringer practice amp using it's 6" speaker. An built my own dual chip bridged amp with a 10" speaker. The bigger speakers move more air and they sound surprisingly good.</p>

<p>Thanks Scott. That's fantastic. Now I know how to wire the 3 pole double throw stomp box switches I got from ebay - which look just like the Stewmac one and feel really solid except I got 10 from China for less than the price of one from Stewmac and it was free postage and packing and arrived in the UK in 8 days.</p>
<p>What software did you use for that diagram? I really like it.</p>
<p>Thanks again</p>

<p>The 2.1mm jack is designed/wired so that the red+ tab receiving the battery positive lead disconnects the battery when the wall wart plug is inserted. Also, the negative lead from the battery to the 2.1mm jack, and the ring of the stereo jack act as the "battery disconnect".</p>
