I have a brand new, out of the box, Texas Star Sweet Sixteen on my bench.
1).... Upgrade power wire, positive and negative, to the board and to the output transformers
2).... Upgrade the 4 filter capacitors from 1000uf 16V to 3300uf 25V
3).... Move the fan thermal switch from the PC board to directly on top of heat sink. There is a spot with room
to do this.
Now then, as found right out of the box.
1).... Guess what, this amplifier came with 8 Toshiba 2SC2879 transistors.
That's right.
But I am fairly sure they are knock-offs ...... But they are damn good knock-offs
They do produce over 1000 watts of power with a very acceptable VSWR
2).... The output transformer balancing/tuning capacitors are large surface mount parts.
First time I've seen this. May be getting hard to get the metal clad capacitors.
3).... The power filter capacitors are 1000uf 16V, lowest value I have seen in a new DX 1600
