[TA Forbes]

Since you brought it up, the 12S568/69 and 12S595 are very good sounding sets. They often fall under the "ignored" Z's.

However, they also fall under the "padding the tube count" type of Z's that I mentioned previously. Two 6X5s, two 6J5s serving as oscillator and 2d detector, and three 6J5s driving/inverting the PP6V6s. Also, there is only ONE I.F. amp.

In my opinion this design sacrifices ability to pull in distant stations, which is something I would think the buyer of an expensive high-tube count set would want.
