The C is a different motherboard but similar circuit, the main difference being that it used IDC connections. It used my recommended 317 IC regulator and a better, toroidal, ac transformer. I think it went over to Carnhill transformers.
I have no idea what changes were included in recent times but I'm equally sure that swapping an IC BA640 for a discrete BA440 was not the main reason for a change in sound.
My guess is that it's a transformer improvement... but that's just a guess.  |
Very interesting!! More differences to them than I would have expected. Does the new one still qualify as a 33609 then? Or more like a valuable spin off?
Are they still using the Carnhill on the new ones?
