Hi guys, There has been a fair bit of talk about the Soldano SLO around the local guys and all rave about them. Not that I NEED a 100w monster. So in my travels on the net this came up. http://diy-fever.com/amps/5-watt-slo/ What a beast!!!! I quickly contacted my valve supplier and he's got hundreds of EL91s, great. As you can see Gary Moore is at the top of the list of my favourites and I was unaware that he played SLO's. This one always makes me CRY So a tribute the greatest blues guitarist. Because the EL91 are plentiful I'm going up the output to about 10w, if I'm lucky The VVR will keep the EL91s happy and the preamp, PI will get the full treatment The schematics will be updated as we go along.
