ISO Chip Amp to Use 28v-0-28v, 2A Toroid
Toroid looking for chip amp for lifetime match. I have two of these I can pull from the RS Accurian amp and would like ideas on a kit I can use them in. I kind of require thru hole layout due to diastrous surface mount experience. 15-25W.

Hi,
your 28Vac transformer will give about +-40Vdc across your biased amplifier. A 3886 will give about 60W into 8ohm from this transformer and the 112VA will suit this well. For <=25W maximum output you either need 16ohm speakers or a lower voltage transformer.
