![]() ![]() Why anyone would need to do that is mostly beyond me (anyone actually got a 32 ohm speaker?!), but there's no reason it wouldn't work. DC power is common in batteries, solar cells, fuel cells, and small electronics. just GROUND the negative speaker terminal (you might have to tap into where the black wire from the OPT grounds inside the chassis) and hook the positive speaker terminal to the 16 ohm tap. 1.DC (direct current) powered devices usually have 2-3 electrical wires. you COULD use a 32 ohm speaker on the HF89. The following requirements on wire color codes apply in Canada: Single Phase, Line (Hot) Black or Red. Primary has 3.5K Plate-to-Plate load with secondary terminations for 4, 8 and 16 ohms. The AC power cable color code is nearly similar to the code used in the USA except exclusion of bare copper from ground wire. Now, the way the transformer is wired, the same transformer could work either way. This transformer uses the same wire color codes as original. ![]() ![]() On the HF89, the feedback was taken from the 4 ohm (green) and 16 ohm (orange) taps, through a rather complex network. Here's the wiring from that one:įrom comparing the HF89 to HF87 schematics, here's the only way I could see that the transformer could be wired in an HF89: If there's five wires on the secondary side with those colors, I don't think it's an HF-89 transformer.
