I am doing an upgrade on this amp. and matching power supply ,It has two 3-500z Eimac tubes ,Connected too the anode of each tube is a paracitic suppresser with 2, 220 ohm 2 watt carb. comp. resisters ,twisted together in paralell.with a silver strap wraped arround them ,I wanted to check the resisters to see if they needed to be replaced and all looked like they have endured high levels of heat ,so I tryed to check the resistance with my ohm meter and they show no resistance at all ,There are two tubes yn this amp and both suppressers show no resistance ,I took both of them out of the circiut and same thing maybe I need to remove the resisters from the metal strap ?can anyone tell me what the deal is with these things???? BK
