Built a Marshall 18 watt 'lite' model today. It's like an 18 watt but only one channel, without the tremolo. Sorry, I don't like tremolo. [img]/images/graemlins/smile.gif[/img]
Here are a few pics. the gut shots aren't real awe inspiring, because I'm still tweaking values, and finshed it late enough tonight that I didn't want to play through it much, since my wife is trying to sleep. Later on I'll make it nice and neat and cleaner looking.
I will probably order a custom faceplate for it (have it already designed, as a matter of fact) and I do have a head enclosure and 1x12 cabinet on it's way. No clips until I get it tweaked a bit - right now it's kinda low on volume and gain, especially volume - it seems a little anemic compared to my Matchless 18 watter, and they should be in the same ballpark, even though I used hammond 125E output iron on it. I'm betting with some phase inverter tweaks I should be able to get it a bit stronger.
The two controls are volume and tone. Two inputs are normal and the 2nd one is paralleled, like a Matchless. I may rewire it later to make the two gain stages seperate and cascade, not sure yet. If I did, I'd also have to add another filter cap... I may do that on my next build. This one may just stay 'stock' so I have a good comparison. One thing that did amaze me is that the Hammond output transformer sounded really good, and this amp has (so far) really nice cleans and an amazing touch sensitivity. You can go from clean to some dirt just by how hard you pick - not even having to mess with the volume knob. If I can keep that and get just a bit more volume and gain I'll be happy.
