Nice place here!
I own a HD-130 head (no reverb/tremolo, SS preamp, all stock) and two 115RH-65 cabinets (all originals).
Since the cabinets are 8 Ohm each (as the specifications on the MM 1977 Amp Catalog), which output impedance setting may I choose from the head?
On the back of the amp there are two speaker outputs linked in series and a switch that says 4 or 8 ohms.
Now, two 8 ohms cabinets in series are 16 ohms total...obviously there is a impedance mismatch with the amp!
Is it safer to put the switch on 4 or 8 ohms position?
On page 17 of the MM1977 amp catalog there is a nice picture of a full stack with a HD-130 and two 115RH-65 cabinets...so Music Man knew that this combination was ok; however, I can't find any information on how to set the impedance in the amp!
Please, help me! :D I don't want to ruin my beautiful amp and cabinets!
