Why not look at the BAL-BAL design from opc here:

Yes, it uses op-amps.
I built the dynalo before. The SS dynalo is similar to dynalo circuit with difference in parts. The problem for SS dynalo is, many BJT are discontinued and need to be replaced by SMD one. Question is, how can I do the matching on SMD??

The board designers switched to SMD for the BJTs some time ago, and the latest boards are now fully SMD. I built one of the boards with the SMD BJT's and there does not seem to be a concern with matching. There is a servo that will take care of any issues in that regard.

The Pioneer Super Linear Circuit
All transistors are matched.
You just need a test socket.
