Simple and inexpensive. I like that. I can easily be done for under $100. Even if you use the more expensive Hammond power transformer.Fred, can you give a listening impression. The 124B is rated for only 150Hz to 15KHz, same as Hammond's 125 series SE output trans. However, a lot of people who have used the 125SE's believe it operates very well outside of specs. JE Labs confirmed that it's actually +/- 1dB between 20Hz to 20KHz. Wonder if its the same for the 124 P/P series?
Gar.
