There are other problems you need to consider as well, like speaker impedance, i.e, 4 / 8 / 16 Ohms.
With the combo, you don't get the flexiblity of chosing the correct impedance.
yeah then there's the issue of the physical size of the speaker fitting into the combo.
One solution is to upgrade to a better quality output transformer.
Where you can mod to have "Speaker Outs" at different impedance
4 / 8 / 16 to attached to any cab.
By the way fyi:
The stock OT is mismatched at 5k, the EL84 needs one to be at 7k.
An upgrade will result in a much louder amp and longer tube life
More fyi: Lol
The head version is DC heated filaments, while the combo one is AC heated.
one of the reasons why i advocate the head unit.
however same problem with the head, mis-matched OT
Sub: I do believe the combo sports an 8", not 10"....seriously, is it really possible for a 12" speaker to fit in a combo?
