Hafler P500 speaker relays are missing.
Can someone tell me what voltage, brand, model number or anything about these? I have both manuals for the p500 and DH500 which are similar but different. Still there is no reference other than there's supposed to be a relay. I bought 2 of these recently that were altered by McCune Audio back in the day. They have one big plug in the back for power and relay circuit. I traced every wire according to the manual/assembly guide. Everything's as it should be with the exception of the relay.
