If it works... and it does  Time owned: more than 12 months
I know all about the non-availability of the output transistors. Yes, Ten-Tec can't get critical parts so they won't repair it anymore. That is hardly news.... I have a Yaesu FT-100D that is only 7 years old and Yaesu won't even touch it. So after 26 years this Hercules 444 is still putting out full output without any issues... I think it has paid for itself.

Bad dream !  Time owned: 6 to 12 months
The final transistors have long been discontinued.
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.

best solid state amp I have owned  Time owned: more than 12 months
I bought this amp new some 12 years ago and my XYL ZS6D has used it with various rigs. It is totally idiot proof and still puts out full rated power.

Pity that the South African currency has dropped so low that bigger amps and expensive gear can only be dreamed about.
