The KT120 is an Octal based part. Perhaps the "Tempest" uses Octal based small signal tubes, but I suspect "hype".

I'd be very cautious about buying any older unit fitted with KT120s. It's likely the OEM complement included KT88 O/P tubes. The KT120 is NOT a drop in replacement for the KT88. Several things can go wrong, including power trafo damage. :>((

Unless circuit modifications are made, there is no benefit to using KT120s in a KT88 amp! If the power trafo lacks the necessary extra "stones", modification should not be attempted.
