Ef2c

I am impressed with the combination. Got the phone first then the amp tonite. It came without the orig transformer. 16 volt AC.
I am using a 12v 2A trans. Not sure if few volt less would make a big difference. Somehow my USB input is not working yet. When plugged in and note book says usb installation ready, i lost both the phone out put and zilch from the usb. Anyways i will try to sort usb out later on. At this moment i am enjoying the analog output. Listening to this fellow. Playing tribute to Shadows.
