B&K ST-140 - Older vs. Newer versions?

I believe the older version had a pushbutton on/off switch, while later versions had a toggled switch. I owned a very early predecessor to the ST140 called the EX140. It is a true dual-mono version of the same amp. It was a great little SS amp and continued to perform well for me for twelve years till I sold it. I've never seen one being sold used. I bought mine at Singer in NYC back in 85'. At the time they sold both the ST and the EX and I did compare the two side-by-side there for some time and ended up liking the EX by a small margin. I think the ST is a great amp for the money on the used market, and I'm not a big fan of most SS in general. The 140's seemed to have a softer edge to them than other SS I've heard, and mine compared favorably to the tube amp I replaced it with, though I did prefer the tubes (Jolida 302B).
