Underside view of the 6T9 baking pan tube amp

The OPTs and printed cct. brd. fit snugly in the thin baking pan chassis making a compact little amp. Drilling such a thin chassis has its challenges and getting all the drilled points to line up with cct. brd. mounting holes can be frustrating. This amp is a poor performer under the CRO but produces an astounding stereo image. It plays small classic quartets, jazz groups and most voice and piano based music well. You need at least 90dB efficient speakers that can go deep for good listening. See the 6T9 Tube Amplifier Project page for more info.
