Hi, I play a Mesa Studio Pre into a Mesa 50/50 Stereo (the old one, not the newer 2:50). The 50/50 Stereo outputs are 8 ohms or 4 ohms. So, I'm gonna buying a 2x12 for home-playing (don't have space for a 4x12 at home!). The cab's got 2 x Celestion Vintage 30 and can be used in mono (8 ohms) or stereo (2 x 16 ohms), so I was wondering what would be less stressful for my poweramp:
1) to use only channel 1 (8 ohm output) and the cab in mono at 8 ohms (no impedance mismatch but channel 2 output will not be connected to anything);
2) to use both channels with an impedance mismatch (poweramp outputs: 2 x 8 ohms, cab: 2 x 16 ohms).
All that keeping in mind that the 50/50 Stereo user manual states the following:
1) "If you opt to use only one channel of the Fifty/Fifty with speakers
connected to only one channel's output(s), you must turn the unused channel's Level control
to zero! Otherwise the channel will be operating without a load, and damage to the tubes
and/or the transformer will result."
2) "Mismatching of speaker
impedance will not cause damage or severe loss of power. (Extreme mismatches will
decrease tube life, however)."
So the manual allows for both the options, but which is less stressful for the poweramp?
Thanks.
