Ten-Tec themselves have said that they can't get one working with modern replacements without a total redesign of the amp. Apparently its a problem of the gain(HFE) of the modern devices not being compatible with the feedback methods used. They can get it right on some bands but not on others. Others I've talked with have confirmed this - not just Ten-Tec. Doug |
