I recently purchased a cab with a G07 inside. When I inspected the back of the monitor I noticed that the glass on the back (vacuum tube?) where that pot connects to, is cracked. I can actually remove the section where the wires are sticking out. When I turn on the cab this area crackles with electricity, but nothing else happens. I see caps kits available, but I've never seen this part available for sale. If the monitor is toast should I just sell it for parts on ebay? The chassis must work somewhat becuase it's transferring power to this tube thing.
Any help would be greatly appreciated.
Thanks
