Marshall 2150 Powercell Combo 1978 Black

Shipping calculated at checkout.

No Sales Tax For Customers Outside Of California.

We brought in a couple of these beasts from the late 70s - the Marshall 100 watt, single 12" combo dubbed the Powercell, aka Model 2150.

This one is completely original, with a slightly different (but original) speaker than the last one we listed:  a Celestion T2975 8 Ohm G12-125, rated at 125 watts.  The speaker handles the 100 watts quite nicely.

We tested all the tubes, cleaned the pots and tube sockets and ran the amp up to make sure everything works well.  This amp can really move some air, and it is right at home running one, even two, 4x12 cabs.

We will ship the amp in three boxes so the heavy speaker and transformers don't cause damage to the cabinet in transit.  Assembly is pretty simple, but not that it will be required on delivery, and shipping will be expensive.
