The main and monitor volume pots on my 828 were very dirty sounding, making pops when turned. I opened the case and sprayed some Tuner/Control Cleaner & Lubricant (contains dichlorofluroethane, white mineral oil, silicone fluid, chlorofluroethane) into the pot casings.

Now it sounds as if I've just shorted out the two volume knobs. All I get is a loud hum. Imagine me swearing a steady stream of profanity.

Did I just kill my 828?
