Many of their kits are with descrete transistors in class A operation. For example the Smartkit 1010 5 input mixer (adder), or the 1024 2 transistor microphone preamplifier. Just visited the Smartkit shop in Athens. Alexandros who is very helpful told me that Quasar E lectronics UK are their best customers, selling their kits. They kindly sent the 1010 5 input mixer instructions and schematic so that a teen atempt on a very nice beige, brown small console Retex box can be repaired.
