How much does the 1600 go for i need 2

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
Yep, I just saw that myself this morning.
I will say that according to what I can see in the video, the 6J coded Toshiba knock-offs are internally more robust and the tabs are connected internally much, much better than the HG transistors.
And the upper & lower ceramic insulators are thick like the genuine Toshiba's whereas the HG's are much thinner and break very easily.
As BBI says, I am not bashing anyone in this case. Just reporting my observations.
This is the same Toshiba 6J code that came in this Sweet Sixteen I have been writing about in this post.
hey ranch55 i talked to you awhile back
