I've got this 2 pill front says Galaxy amp with 1446 finals. It went from 150 watts to about 55. I opened it up found a burnt resistor next 2 one of the finals. I bought Chinese 1446's replaced the resistor and now have nothing. Could both the Chink finals be bad? I have a transistor tester and Fluke 88 not sure how to check them any help would be appreciated, I did install the end with the angle on it the same way the old ones came out. Thanks in advance for your time.
