Hi, twice I requested the free 303 upgrade manual. I didn't receive anything. The link to a second partie was received, so my request must have reached somebody.
Something positive, good site!!!

Just completed your 33 mod and my quad pre-amp is now far too good for the amp, so I guess that will be next. I am very impressed for a small outlay. Superb components and excellent service. Now I wonder what you think of the Richard Brice mod on the amp boards transforming the two transistor stage into emitter-follower. I hate tone controls anyway, but is it safe and worthwhile. I would love to know your oppinion. The mod can be found on Thank you. Barry
