Keep in mind the old tube amps are ratings are based on the amp volume still being in "clean terrntory". A 100 watt Marshall can be putting out 100 watts at 3, 4 or 5 on on the volume control. With the volume on 10, the head can be putting out 200 to 250 watts!! The speakers will last for a while, but pushing the speakers will reduce the life of the speaker and will cause them to wear out and blow sooner than if you use a lower watt amp.

I'd go with a 50 watt head with a single 1960ax cab. Or, two cabs with the 100 watt head or get an attenuator to help burn off the extra wattage from the 100 watt head.

Also, keep in mind, a doubling of amp wattage only results in 4 to 5 db more volume. So a 50 watt amp will only be 4 to 5 db louder than a 25 watt amp, a 100 watt amp will only be 4 to 5 db lounder than a 50 watt amp, ect.

Get a 50 watt head, or even a 30 watt JTM 45 will be plenty loud enough.
