Short During Voltage Checks (Resolved)

[Whitm0]

Hello, during my voltage checks for the Stereomour II I accidentally shorted the terminals while checking terminal 30 or 34 (I cannot remember the exact one). There was a rather loud bang, and then nothing as I jerked away my probe. After this I immediately unplugged the amp and checked the fuse (not blown). I decided to return to the voltage checks and immediately they were off, terminal 1 shows ~6 volts so I unplugged it all and decided to ask here. All resistance checks prior to this were spot on and voltage checks 1-30ish were also perfect. I've also attached a photo of the amp below. Thank you for any and all help.

Edit: The 130 Ohm 2W resistors between terminals 30 and 27 and 30 and 44 appear to be blown, so I'll try replacing those first.

Good news it was just those fried resistors, amp is up and running and sounds great!

I'm glad you were able to find those open resistors. They tend to be the weakest link in the high voltage power supply, and will open up more quickly than the fuse under certain conditions. Thankfully they are inexpensive to replace!
