Picked up one of these to play with. Word on the net is that it has a good phono section for the price from mostly I think non diy folks. What do you diy guys think?

Plan is to replace any out of spec electrolytics. Read that the VD1212 diodes are unstable and should be replaced with two 1N4148 in series and the 2SC458 transistors should be replace with KSC1845 ones.

I know it's allot to look at but would appreciate any input.
