Hi All,
Noobie here. Just finishing up my Plexi Mk II build.
I just finished wiring the output transformer to the impedance selector switch and speaker jacks.
The instructions say to check for a short between the two terminals of the speaker jack. I definitely got continuity. Not surprising, since the four leads from the transformer are all connected.
So I did a resistance measurement. Here’s what I got:
Impedance switch at 4 ohms: ~0.3 ohms between tip and body of jack 8 ohms: ~0.5ohms 16 ohms: ~ 0.9 ohms
When I connected a speaker cable, all of these measurements went up by about .2 ohms..
Does this sound about right?
