I have a book or rather 60′s hard cover catalog that features 10 different lectrolab amps including that s950 model, which was appearently sold as a piggy back with a two 12 cab.
Does that book happen to include the Model R203? My buddy has had this amp his whole life, and we plan to make a clone or two in order to keep the original in current condition. After looking all over the webs, we realized that there is very little info to be found on Sound Projects or Lectrolab amps. I have a ton on pics of the inside of this amp, parts list, and schematic in progress. Any info would be greatly appreciated. Thanks in advance.
Dave – I’ve found an old catalog page that shows the R203. There is a picture, but very little information, not even the brand or model! You can see it at:

about 2/3 of the way down the page.
