Hello. Just got done revamping the amp and P/S board in my 2216. New caps, all new transistors and 4 new .22 ohm resistors next to the output transistors. Plugged into a DBT and all was good. Had good sound from both channels. Plugged into a regular outlet and powered up. POOF!! Smoke from the left channel somewhere Looks like the .22ohm resistors got hot. Not sure what is shorted. Replaced the outputs. They were toast. Checked all solder joints etc... seem fine. When I check the voltage going to the amp it only about 27vdc. When I unhook the red power wire and measure at the terminal it jumps to 47 Vdc. Need some input. Thanks in advance.
